After you create a Unified Messaging (UM) dial plan, you can view and configure a variety of settings. For example, you can configure the level of Voice over IP (VoIP) security, the audio codec, and dialing restrictions. The settings that you configure on the UM dial plan affect all users who are associated with the dial plan through a UM mailbox policy.

What Do You Want to Do?

Use the EMC to view or configure UM dial plan properties

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "UM dial plans" entry in the Unified Messaging Permissions topic.

  1. In the console tree, navigate to Organization Configuration > Unified Messaging.

  2. In the work pane, click the UM Dial Plans tab, and then select the UM dial plan that you want to configure.

  3. In the action pane, click Properties.

  4. Use the General tab to view specific dial plan settings or enable or disable features for UM-enabled users:

    • Associated UM servers   This section displays the Unified Messaging servers associated with a dial plan. The Unified Messaging servers listed in this section process incoming calls for users who are associated with the dial plan. Unified Messaging servers can be associated with single or multiple dial plans. You must use the UM Server Settings properties tab in the Unified Messaging server's properties to add a Unified Messaging server to a dial plan.

    • Associated UM IP gateways   This section displays the UM IP gateways associated with a dial plan. The UM IP gateways listed in this section process incoming calls for users who are associated with the dial plan. A UM hunt group establishes a link between a UM dial plan and a UM IP gateway and can also be associated with a dial plan by first being associated with a UM IP gateway. You can associate a UM IP gateway with a dial plan when you create a UM hunt group.

    • URI type   A Uniform Resource Identifier (URI) is a string of characters that identifies or names a resource. The main purpose of this identification is to enable VoIP devices to communicate with other devices over a network using specific protocols. URIs are defined in schemes that define a specific syntax and format and the protocols for the call. After you create a UM dial plan, you won't be able to change the URI type without deleting the dial plan, and then re-creating the dial plan to include the correct URI type. You can select one of the following URI types for the dial plan:

      Telephone extension   This is the most common URI type. The calling and called party information from the IP gateway or IP Private Branch eXchange (PBX) is listed in one of the following formats: Tel:512345 or 512345@<IP address>. This is the default URI type for dial plans.

      SIP URI   Use this URI type if you must have a Session Initiation Protocol (SIP) URI dial plan such as an IP PBX that supports SIP routing or if you're integrating Microsoft Office Communications Server 2007 and Microsoft Exchange Server 2010 Unified Messaging. The calling and called party information from the IP gateway or IP PBX is listed as a SIP address in the following format: sip:<username>@<domain or IP address>:Port.

      E.164   E.164 is an international numbering plan for public telephone systems in which each assigned number contains a country code, a national destination code, and a subscriber number. The calling and called party information sent from the IP gateway is listed in the following format: Tel:+14255550123.

    • Number of digits in the extension   This is the number of digits in the extension numbers for users who are associated with this dial plan. For example, if a user associated with a dial plan dials a 4-digit extension to call another user in the same dial plan, select 4 as the number of digits in the extension.

      The number of digits for extension numbers is based on the telephony dial plan created on a PBX. This is a required field that has a value range from 1 through 20. The typical extension length is from 3 through 7 digits. If your existing telephony environment includes extension numbers, you must specify a number of digits that matches the number of digits in those extensions when you create the UM dial plan.

    • Modified   This field shows the last date and time the dial plan settings were modified.

    • Allow users to receive faxes   Select this check box to allow fax messages to be received by users who are associated with the dial plan. If you don't select this check box, all users who are associated with the dial plan won't be able to receive fax messages in their Inbox. By default, this setting is enabled.

    • Allow user to configure call answering rules   Select this check box to allow users associated with the dial plan through a UM mailbox policy to be able to create and configure call answering rules. When this setting is selected, UM-enabled users can create rules or actions and apply conditions to an incoming call to their phone number. They can transfer the call, have the caller leave a voice mail, or allow the caller to locate them at a different phone number.

    • VoIP security   Use this drop-down list to select the VoIP security setting for the UM dial plan. You can select one of the following security settings for the dial plan:

      Unsecured   By default, when you create a UM dial plan, it communicates in an unsecured mode, and the Unified Messaging servers associated with the UM dial plan send and receive data from IP gateways, IP PBXs, and other Exchange 2010 computers using no encryption. In unsecured mode, both the Realtime Transport Protocol (RTP) media channel and SIP signaling information aren't encrypted.

      SIP secured   When you select SIP secured, only the SIP signaling traffic is encrypted, and the RTP media channels still use TCP, which isn't encrypted. Mutual Transport Layer Security (TLS) is used to encrypt the SIP signaling traffic.

      Secured   When you select Secured, both the SIP signaling traffic and the RTP media channels are encrypted. A secure signaling media channel that uses Secure Realtime Transport Protocol (SRTP) also uses mutual TLS to encrypt the VoIP data.

      A Unified Messaging server can operate in any mode configured on a dial plan because the Unified Messaging server is configured to listen on TCP port 5060 for unsecured requests and TCP port 5061 for secured requests at the same time.

  5. Use the Subscriber Access tab of the UM dial plan that you have selected to configure subscriber access settings for the UM dial plan. A subscriber is an internal business user or network user who is enabled for Exchange 2010 Unified Messaging. Outlook Voice Access enables subscribers to access their individual mailboxes to retrieve e-mail, voice messages, contacts, and calendaring information using a telephone. You can view or configure the following:

    • Welcome greeting   This display-only field shows the name of the sound file that will be used for the welcome greeting. Click Modify to specify the audio (.wav) file to use for the welcome greeting. If you don't specify an audio file, callers will hear a default welcome greeting that says, "Welcome, you are connected to Microsoft Exchange."

      The welcome greeting is used when Outlook Voice Access users or another caller calls the subscriber access number. This audio file is the default greeting for a specific UM dial plan. However, you may want to change this greeting and provide another welcome greeting specific to your company, such as, "Welcome to Outlook Voice Access for Contoso, Ltd."

      If you decide to customize this greeting, you must first record the customized greeting, save it as a *.wav file, and then configure the dial plan to use this customized greeting. The file name and path must not exceed 255 characters.

      You can configure a customized business hours greeting by clicking Modify to select a previously recorded custom greeting file. You can select one of the following:

      Use default greeting   Use this option to enable the default welcome greeting to be played to callers. By default, this option is enabled.

      Use custom greeting file   Use this option when you want to enable a custom welcome greeting file to be played to callers. Click Browse to locate a custom welcome greeting file that was previously recorded.

    • Informational announcement   When enabled, this optional recording plays immediately after the business or non-business hours greeting. An informational announcement may state the organization's hours of operation, for example, "Our business hours are 8:30 A.M. to 5:30 P.M., Monday through Friday and 8:30 A.M. to 1:00 P.M. on Saturday." An informational announcement can also provide information that's required for compliance with company policy, for example, "Calls may be monitored for training purposes." If it's important that callers hear the whole informational announcement, it can be marked as uninterruptible.

      By default, there's no informational announcement configured on UM dial plans or auto attendants. Use the following options to enable an informational announcement and use a custom audio file specific to your organization. The recordings must have already been recorded as .wav files. You can select the following:

      Disable announcement   Use this option to disable an informational announcement. By default, this option is enabled.

      Informational announcement file   Use this option when you want to enable an informational announcement to be played to callers. Click Browse to locate a custom informational announcement file that was previously recorded.

      Allow informational announcement to be interrupted   Use this option to enable the informational announcement to be interrupted by the caller. This should be enabled if you have long informational announcements. Callers may become frustrated if the informational announcement is long and they can't interrupt the informational announcement to access the options provided by the UM dial plan or auto attendant.

    • Enter the telephone number to associate   Use this field to add a telephone number or extension that a user will call to access the Unified Messaging system using Outlook Voice Access. In most cases, you enter an extension number or an external telephone number. However, because this field accepts alphanumeric characters, a SIP URI can be used if you're using an IP PBX.

      By default, when a dial plan is created, no subscriber access numbers are configured. To enable subscriber access, you must configure at least one telephone number. The number of alphanumeric characters can't exceed 20.

      When you configure this number on the dial plan, this number will be displayed in the Microsoft Office Outlook 2007 and Outlook Web App for Exchange 2010 voice mail options.

  6. Use the Dial Codes tab to configure the dial codes for a UM dial plan. Several dial code settings can be configured on the dial plan. These include incoming and outgoing calling options. You can configure the following:

    • Outside line access code   Use this field to type the number or numbers used to access an outside telephone number for outgoing external calls. This number will precede the telephone number dialed. This is also called a trunk access code. This field accepts from 1 through 16 digits. For many organizations, this number is 9. By default, this field isn't populated.

      Frequently, this setting is used in telephony environments where a PBX is located onsite or maintained in an organization. It may not have to be configured if your organization's telephony environment is maintained by an external business or vendor.

    • International access code   Use this field to type the number code used to access international telephone numbers for outgoing calls. This number will precede the telephone number dialed. By default, this field isn't populated. This field accepts from 1 through 4 digits. For example, the international access code for the United States is 011. For Europe, it's 00.

    • National number prefix   Use this field to type the number code used to dial telephone numbers that are out of an area code but within the country/region. This number will precede the telephone number dialed. By default, this field isn't populated. This field accepts from 1 through 4 digits. For example, 0 is used in Europe, and 1 is used in North America.

    • Country/Region code   Use this field to type the country/region code number used for outgoing calls. This number will precede the telephone number dialed. By default, this field isn't populated. This field accepts from 1 through 4 digits. For example, in the United States, the country/region code is 1. In the United Kingdom, it's 44.

    • In-country/region number format   Use this field to specify how a user's telephone number should be dialed by the Unified Messaging server in a different dial plan, which has the same country code. This is used by an auto attendant and when an Outlook Voice Access subscriber searches and tries to call the user in the directory.

      This entry consists of a number prefix and a variable number of characters (for example, 020xxxxxxx).

      To determine the telephone number, Unified Messaging will append the last x digits from the telephone number specified in the directory to the prefix specified.

    • International number format   Use this field to specify how a user's telephone number should be dialed by the Unified Messaging server in a different dial plan, which has a different country code. This is used by an auto attendant and when an Outlook Voice Access subscriber searches and tries to call the user in the directory.

      This entry consists of a number prefix and a variable number of characters (for example, 4420xxxxxxx).

      To determine the telephone number, Unified Messaging will append the last x digits from the telephone number specified in the directory to the prefix specified.

  7. Use the Features tab to configure the UM dial plan features. Several features can be configured on the UM dial plan. These include transferring calls and sending voice messages. You can configure the following:

    • Allow callers to transfer to users   Select this check box to enable callers to transfer calls to users. By default, this option is enabled. This lets users associated with the dial plan transfer calls to users in the same UM dial plan. After you select this check box, you can set the group of users to whom callers can transfer by selecting the appropriate option under the Callers can contact section on this page.

      If you disable this option and disable the Allow callers to send voice message setting, the options under Callers can contact will also be disabled.

    • Allow callers to send voice messages   Select this check box to enable callers to send voice messages to users. By default, this option is enabled. This lets users who are associated with the dial plan send voice messages to users in the same UM dial plan. After you select this check box, you can set the group of users to whom callers can send voice messages by selecting the appropriate option under the Callers can contact section on this page.

      If you disable this option and disable the Allow callers to transfer users setting, the options under Callers can contact will also be disabled.

      If you disable this option, the auto attendant won't invite callers to send a voice message during a system prompt.

    • Callers can contact   Use these options to determine a grouping of users to use. By default, the Users within this dial plan option is selected. However, you can change the grouping of users to allow callers to transfer calls or send voice messages to users located in the global address list (GAL) or to a specific set of users contained in a custom address list by choosing from the following:

      Users within this dial plan   Use this option to allow callers who connect to the UM auto attendant to locate and contact users who are within the dial plan associated with the UM auto attendant.

      Anyone in the default global address list   Use this option to allow callers who connect to the UM auto attendant to locate and contact anyone who is listed in the GAL. This includes all users who are mailbox-enabled.

      Only this extension   Use this option to allow callers to connect to an extension number that you specified in the field for this option. This field accepts only numeric digits. The number of digits that you define in this field must match the number of digits configured on the dial plan associated with the auto attendant.

      Only this auto attendant   Use this list to allow callers to connect to a UM auto attendant and then connect to another auto attendant. You must create this auto attendant to allow callers to be transferred to another auto attendant that's specified.

      Anyone in this address list   Use this option to allow callers who connect to the UM auto attendant to locate and contact users who are within a defined custom address list. This includes all users who are mailbox-enabled.

      Important:
      The All Address Lists container is an empty container object and differs from the GAL container. If you choose the All Address Lists container when you browse for a custom address list, there will be no UM-enabled users for callers to contact. If you want to select all the address lists in your organization, choose the Anyone in the default global address list option.
    • Matched name selection method   Use this field to select the method the dial plan uses to differentiate between users who have similar names. When a caller is prompted to enter letters to find a particular user in the organization, sometimes more than one name matches the caller's input. By default, all UM auto attendants associated with this dial plan inherit this setting. However, you can change this setting on each UM auto attendant created.

      Select one of the following methods for providing callers with more information to help them locate the correct user in the organization:

    • None   No additional information is given when matches are listed. By default, this method is selected.

    • Title   The auto attendant includes each user's title when matches are listed.

    • Department   The auto attendant includes each user's department when matches are listed.

    • Location   The auto attendant includes each user's location when matches are listed.

    • Prompt For Alias   The auto attendant prompts the caller for the user's alias.

  8. Use the Settings tab to configure dial plan settings for Unified Messaging. When you configure settings on this tab, you can control how internal and external callers locate users in the system, the number of logon failures allowed when internal users try to access their voice mail, and the default language that the dial plan uses. You can configure the following:

    • Dial by name primary method   Use this list to select the primary way that callers can locate a user when they dial in to the system.

      By default, Last name, First name is selected. This means that when users are searching for a user in the directory, they will enter the user's last name first and then the first name.

      When a subscriber or a UM-enabled user uses the subscriber access number to access the Unified Messaging system, they can access the menu that enables them to spell the name or alias to locate a user in the system. The option selected is the default method used by UM-enabled users.

      You must select one of the supported methods to be able to use the dial-by-name primary method. The following methods are supported:

      Last First (default)

      First Last

      SMTP Address

    • Dial by name secondary method   Use this list to select the secondary way that callers can locate a user when they dial in to the system.

      By default, SMTP address is selected. This means that when users search for a user in the directory, they will enter the user's e-mail alias or SMTP address.

      When subscribers or UM-enabled users use the subscriber access number to access the Unified Messaging system, they can access the menu that enables them to spell the name or alias to locate a user in the system.

      You aren't required to select one of the four methods that are supported. However, if you don't select a secondary method, callers are given only one method to use to spell a user's name in the system. The following options are available:

      Last First

      First Last

      SMTP address (default)

      None

    • Audio codec   Use this list to select the audio codec that will be used by the dial plan. When a caller places a call to a user who is associated with the dial plan, Unified Messaging uses the audio codec that you select from this list to record voice messages that will be sent to UM-enabled users. The following audio codecs are supported:

      MP3 (default)

      WMA (Windows Media Audio)

      G711 (Pulse Code Modulation (PCM) Linear)

      GSM (Group System Mobile 06.10)

      By default, the MP3 format is selected. The MP3 format is a common audio file format that's used to greatly reduce the size of the audio file and is most commonly used by personal audio devices or MP3 players. MP3 is a cross-platform type of audio codec and is used for compatibility with many mobile phone and devices and various computer operating systems.

      WMA is used because it's highly compressed and has high quality format properties. G.711 PCM Linear is a telephone quality audio codec format that's the least compressed and has the lowest quality format. GSM 06.10 is an audio codec format that's used by mobile phone vendors and is the standard for digital mobile phone services.

      If you're concerned about users' disk quotas, select WMA as the audio codec. Voice files saved in .wma format are approximately half the size of the same voice recording made using one of the other audio codecs.

    • Operator extension   Use this text box to enter the telephone number or an extension number for the dial plan's operator.

      You can configure this setting to transfer calls to an auto attendant if one is configured, to a human operator, to external telephone numbers, or to extension numbers.

      When a caller who is using the telephone keypad presses 0, or says "reception" or "operator," or the number of Input retries threshold is exceeded, the caller is transferred to the telephone number that you specify in this text box.

      This telephone number can be a number external to the organization or an internal telephone extension number. For example, if the extension number for the receptionist or operator is 81964 and your organization has only one dial plan, enter 81964.

      By default, this setting is blank. If you don't enter a number in this text box, the ability to transfer calls to the operator is disabled and callers are politely disconnected because there's no one to answer the call.

      We recommend that you populate this text box with a telephone number that transfers callers to an operator if they can't locate a specific user in the directory.

    • Logon failures before disconnect   Use this text box to enter the number of sequential unsuccessful logon attempts allowed before a caller is disconnected.

      The value of this setting can be from 1 through 20. Setting this value too low can frustrate users. For most organizations, this value should be set to the default of three attempts.

    • Maximum call duration (min)   Use this text box to enter the maximum number of minutes that an incoming call can be connected to the system without being transferred to a valid extension number before the call is ended. For most organizations, this value should be set to the default of 30 minutes.

      This setting applies to all kinds of calls. This includes incoming subscriber access calls, voice calls internal to your organization, and voice calls external to your organization.

      The value of this setting can be from 10 through 120. Setting this value too low can cause incoming calls to be disconnected before they are completed. For example, if your organization receives many large fax messages, you may want to consider increasing this value from the default so that all the pages for fax messages are received.

    • Maximum recording duration (min)   Use this text box to enter the maximum number of minutes allowed for each voice recording when a caller leaves a voice mail message. For most organizations, this value should be set to the default of 20 minutes.

      The value of this setting can be from 1 through 100. Setting this value too low can cause long voice messages to be disconnected before they are completed. Setting this value too high lets users save lengthy voice messages in their Inboxes.

      This setting is important if you have implemented strict disk quotas for users. This value must be less than the value set for the Maximum call duration (min) setting.

    • Recording idle time-out (sec)   Use this text box to enter the number of seconds of silence that the system allows when a voice message is being recorded before the call is ended. For most organizations, this value should be set to the default of 5 seconds.

      The value of this setting can be from 2 through 10. Setting this value too low can cause the system to disconnect callers before they are finished leaving their voice messages. Setting this value too high allows lengthy silences in voice messages.

    • Input failures before disconnect   Use this text box to configure the number of times that callers can enter incorrect data before they are disconnected. For most organizations, this value should be set to the default of three attempts. This is an important setting for speech-enabled UM dial plans.

      Examples of incorrect data include when a caller requests an extension number that isn't found in the system, the system can't locate the user's extension number to transfer the call, or the caller presses a menu option that isn't valid.

      The value of this setting can be from 1 through 20. Setting this value too low may prematurely disconnect the caller.

    • Default language   Use this list to specify the default language used by callers. When a caller places a call to a user who is associated with a dial plan, this is the default language that the voice recorded operator uses. The system prompts that callers hear are also played in the default language. The language that is chosen on the UM dial plan is used to read e-mail, voice mail and calendar items; say the user’s name if a personal greeting hasn’t been recorded; transcribe a voice message using the Voice Mail Preview feature; enable Automatic Speech Recognition (ASR) to work correctly.

      By default, if you install U.S. English with Exchange 2010, only one language is listed in this list. To have other language options available, you must install the UM language pack for each language you want to include. For more information about how to install a UM language pack, see Install a Unified Messaging Language Pack on a UM Server.

      Adding other languages lets subscribers use a language other than U.S. English. For example, if a subscriber calls in to the Unified Messaging system using the subscriber access number from a desk telephone, the subscriber is greeted with a prerecorded operator's voice in English. Even if the same user selects a different language in Outlook Web App, such as French, the menus are still read in U.S. English. For the user to be able to hear the prerecorded operator menus in French, you must install the appropriate language.

  9. Use the Dialing Rule Groups tab on the UM dial plan to specify dialing rule groups for in-country/region and international calls placed by UM-enabled users. Each dialing rule entry defined on the dialing rule group determines the types of calls that users within a specific dialing rule group can make. After you use the Dialing Rule Groups tab to configure a dialing rule group, you must configure the UM mailbox policy to use the appropriate dialing rule group. After you configure the UM mailbox to use a dialing rule group, the dialing restrictions configured apply to all UM-enabled users who are associated with the UM mailbox policy. For example, you can configure a dialing rule group that doesn't require users who are associated with the dial plan to dial an outside line access code when they place a call to an in-country/region telephone number. You can configure the following:

    • In-Country/Region Rule Groups   Use this text box to add, remove, or edit in-country/region dialing rule groups used by UM mailbox policies.

    • International Rule Groups   Use this text box to add, remove, or edit international dialing rule groups used by UM mailbox policies.

    • Dialing Rule Entry   Use this dialog box to define the telephone numbers and number masks for in-country/region and international calls that will be made by UM-enabled users. Each dialing rule entry determines the types of calls that users within a dialing rule group can make. However, you must correctly configure the dialing rule entry with a number mask and a dial number. After you use the Dialing Rule Entry window to configure a dialing rule entry, you must configure the UM dial plan, mailbox policy, or auto attendant to use the appropriate dialing rule group. You can configure the following:

      Name   Use this list to select a name of an existing dialing rule entry. Or, if you want to create a dialing rule entry, type the name of the dialing rule entry. This is the display name for the dialing rule entry that will be displayed in the EMC. This field can contain only text characters. The display name for the dialing rule entry can contain up to 32 characters.

      Number Mask   Use this text box to define the number mask for the dialing rule entry. A number mask is used to define the telephone number format that a Unified Messaging server uses to determine what outgoing telephone number it will dial for a user. When an outgoing call is made to a number matched by the number mask on the dialing rule entry, the Unified Messaging server substitutes the digits matched into the dialed number. It then uses the digit string from this match to make the outgoing call. An example of a valid number mask is 91425xxxxxxx. This field can contain only numbers and the character x.

      Dialed Number   Use this text box to define the dialed number for the dialing rule entry. The dialed number is used to determine the actual dial string sent to the IP gateway. This number can be different from the number obtained by Unified Messaging for the outgoing call. However, your PBX can also be configured to omit the area code for local calls and can be configured for private voice numbering plans. Any wildcard characters (x) in the dial string are substituted with the digits from the original number that were matched by the number mask on the dialing rule entry. An example of a valid dialed number is 9xxxxxxx. This field can contain only numbers and the character x.

      Comment   Use this text box to input a comment or description for the dialing rule entry that you're adding or modifying. By default, this text box is blank.

      Important:
      If you've integrated Exchange Unified Messaging and Office Communications Server, you'll probably find it unnecessary to configure dialing rules or dialing rule groups in Exchange Unified Messaging. Office Communications Server is designed to perform call routing and number translation for users in your organization, and will also do this when the calls are made by Exchange Unified Messaging on behalf of users.
  10. Use the Dialing Restrictions tab on the UM dial plan properties to configure dialing rule entries for callers who call in to a subscriber access number configured on a UM dial plan. You can restrict the type of calls placed by callers when an unauthenticated user or an Outlook Voice Access user calls in to a subscriber access number configured on a dial plan by configuring dialing rule groups and dialing restrictions. You can configure the following:

    • Allow calls to users within the same dial plan   Select this check box to let users who call in to a subscriber access number configured on a dial plan place or transfer calls to an extension number associated with a UM-enabled user who is within the same dial plan. By default, this setting is enabled.

      When you disable this setting, users who call in to the subscriber access number won't be able to place or transfer calls to any users who aren't UM-enabled, to other extension numbers, or to UM-enabled users who are associated with the same dial plan. This is because the Allow calls to extensions setting is disabled by default.

    • Allow calls to extensions   When this setting is disabled, users who call in to a subscriber access number on the dial plan can't place calls to users who aren't UM-enabled or to other extension numbers not associated with a UM-enabled user. However, they can place a call or transfer a call to extension numbers associated with UM-enabled users. This is because the Allow calls to users within the same dial plan setting is enabled by default. The Allow calls to extensions setting is disabled by default.

      When this setting is enabled, users who call in to a subscriber access number configured on the dial plan can place calls to users who aren't UM-enabled, to other extension numbers not associated with a UM-enabled user, and to UM-enabled users. This is because the Allow calls to users within the same dial plan setting is enabled by default.

      You can enable this setting in an environment where not all users have been UM-enabled. This setting is also useful when you want to allow users who call in to a subscriber access number configured on a dial plan to call extension numbers that aren't associated.

    • Select allowed in-country/region rule groups from dial plan   Use this section to add or remove allowed in-country/region dialing rule groups. By default, there are no in-country/region dialing rule groups configured on UM dial plans.

      In-country/region dialing rule groups are used to allow or restrict the telephone numbers within a country or region that any user who has dialed in to the subscriber access number can dial. This helps prevent unnecessary or unauthorized telephone calls and charges.

      To add in-country/region dialing rule groups, you must first create the appropriate in-country/region dialing rule groups on the dial plan, and then add the appropriate dialing rule entries on the dialing rule groups.
