Attendant console users who are answering calls for the corporate main phone number can be reached internally by this extension. The best way to implement this functionality with Office Communications Server 2007 R2 is to use Office Communications Server 2007 R2 response group functionality in conjunction with the Communicator Attendant console. Office Communications Server 2007 R2 Response Group Service will route calls using different distribution algorithms to available extensions that are running the Communicator Attendant console. There is no difference for Office Communications Server 2007 R2 if callers are coming from the public switched telephone network (PSTN) or if internal Office Communications Server 2007 R2 endpoints are calling the Office Communications Server 2007 response group Attendant queue.

An auto attendant allows a caller to speak the name of the person to be called and will automatically connect to the person’s extension. Exchange 2007 Unified Messaging (UM) provides with its auto attendant feature provides this functionality to inbound callers. Exchange 2007 UM auto attendant allows an inbound caller to state the name of a designated communication partner and will query Active Directory Domain Services (AD DS) to find the extension of this designated communication partner before actually transferring the call to the destination. If multiple names match, Exchange 2007 UM auto attendant presents all results found, and the caller can pick the appropriate contact.

An automatic call distribution (ACD) system automatically routes incoming calls to agents using a variety of different routing algorithms like time based, skill based, priority level based, and traffic based. There is a wide range of scenarios subsumed under ACD functionality. This ranges from simple hunt group distribution algorithms to highly complex call center "follow-the-sun" routing algorithms covering not just calls but instant messages, voice mail messages, and Web requests. The Office Communications Server 2007 R2 Response Group Service has been designed for user help desk scenarios and intelligent hunt group call distribution, but it does not target the market of the professional call center market. For an actual project it is recommended that you check the detailed feature list of Office Communications Server 2007 R2 Response Group Service against the required functionality of an actual scenario to determine whether Office Communications Server 2007 R2 Response Group Service serves those needs.

Calls will be automatically placed on hold by the system when a user is already in a call and accepts a second call without starting a conference call. This feature is provided by Office Communications Server 2007 R2. In every situation where the user has multiple calls at the same time and has not joined two or multiple calls to a conference, all calls will be placed on hold except for the one call in which the user actively participates at any given moment. There is no differentiation for Office Communications Server 2007 R2 if the calls were inbound or outbound calls.

Only calls to freecall numbers, calling card calls, or collect calls can be initiated from an extension configured for Billed Calls only. Office Communications Server 2007 R2 Outbound Routing enables you to restrict even single extensions from dialing prohibited numbers. This can be as granular as a single number that can only be dialed from such an extension.

Mainly: Incoming calls to a boss phone number need to be redirected to a secretary’s phone number. This functionality is provided by Office Communications Server 2007 R2. As stated above, the wide range of functionalities that can be subsumed under this set of features has received another dimension with Office Communications Server 2007 R2 as instant messages, video calls, and desktop sharing invitations that are addressed to the boss will also be handled by the secretary first before forwarding to the boss.

A call center consists of agents assigned to call queues for answering incoming calls, monitored by supervisors. While for a small company user helpdesk scenario, sometimes a simple hunt group is sufficient to distribute calls among the agents, a larger company may require a "follow-the-sun" call center with thousands of call center agents placed all over the globe. This said, the functionalities and flexibility of the Office Communications Server 2007 R2 Response Group Service need to be checked against the customer requirements given the fact that there is no hard line where user helpdesk scenarios will turn into call centers.

An incoming call will be forwarded to a defined destination if the user does not answer the call after a specified time. Office Communications Server 2007 R2 provides this functionality.

A call forwarding settings can be changed by the user without having access to a company private branch exchange (PBX) extension. Office Communications Server 2007 R2 with its remote access scenarios provides this functionality. As soon as the user is connected on the Internet to an Office Communications Server 2007 R2 Edge Server, the user is able to use her client as being in the office. This includes changing of the call forwarding destination. However, it is not possible to dial into Office Communications Server from the PSTN in order to change the call forwarding settings.

Incoming calls will be forwarded immediately to a defined destination. Office Communications Server 2007 R2 provides this functionality.

The PBX phone stores a list of last numbers dialed, received, or not answered.

When transferring a call, the user transferring the call is able to speak to the transfer destination before actually transferring the call. With Office Communicator 2007 R2 this functionality is possible by establishing an independent secondary connection to the call transfer destination user. Once the secondary connection has been established the first call (transferee) will be on hold. For connecting the call, the conversation with the transferee needs to be selected out of the call transfer drop-down list in the secondary conversation window. The call will be transferred. Office Communications Server Attendant provides an even better user experience with an attended call transfer.

When transferring a call the user transferring the call transfers the call to a destination without talking to the destination user beforehand. This functionality is provided by Office Communications Server 2007 R2 with the Office Communicator 2007 R2 and Office Communicator Phone Edition clients.

If a user works from a different workspace than usual in the company, she is able to reconfigure her extension to the phone standing on this temporary workspace by dialing a special code. If the user has a Windows PC on her temporary workspace that is joined to the domain and has Office Communicator 2007 R2 installed, the user is able to use her system credentials to log into her workspace from this PC. With this, she will also receive all phone calls to this workspace.

This functionality allows a user to type in a code at a random PBX extension that will change the call forwarding setting of the user’s original extension to forward calls to this random extension. Office Communications Server 2007 R2 provides this functionality through the use of Office Communicator Mobile on the user’s mobile phone. Users can also change their call forwarding settings by logging on to Office Communicator 2007 R2 from a domain-joined network PC.

A hunt group is a collection of extensions that will all be rung on an incoming call using a variety of algorithms to influence the order of when to ring which extension.
