Create a topology that includes the Conferencing workload, including a Mediation Server and PSTN gateway, and deploy the Enterprise pool or Standard Edition Server

1. Run the Communications Server Planning Tool to configure your topology, and export the topology into Communications Server Topology Builder. While configuring the topology, select the dial-in conferencing option.
   
   
2. Publish the topology and deploy the Enterprise pool or Standard Edition Server.
   
   
3. If necessary, create a stand-alone Mediation Server and associate it with a PSTN gateway.
   
   

   Note:

   This step is required only if you do not deploy Enterprise Voice and do not collocate the Mediation Server with the Enterprise Edition Front End Server or Standard Edition Server. If you deploy Enterprise Voice, you install and configure Mediation Servers and PSTN gateways as part of the Enterprise Voice deployment. If you collocate the Mediation Server, you install and configure the Mediation Server as part of the Enterprise pool or Standard Edition Server deployment.

Configure dial plans

A dial plan is a set of phone number normalization rules that translate phone numbers dialed from a specific location to a single standard (E.164) format for purposes of phone authorization and call routing. The same phone number dialed from different locations can, based on the respective dial plans, resolve to different E.164 numbers, as appropriate to each location. If you deploy Enterprise Voice, you set up dial plans as part of that deployment, and you need to ensure that the dial plans also accommodate dial-in conferencing. If you do not deploy Enterprise Voice, you need to set up dial plans for dial-in conferencing.

Use the Communications Server Control Panel or Communications Server Management Shell to set up dial plans as follows:

1. Create one or more dial plans for routing dial-in access phone numbers.
   
   
2. Assign a default dial plan to each pool. Set the Dial-in conferencing region to the geographic location to which the dial plan applies. The region associates the dial plan with dial-in access numbers.

Configure conferencing policy to support dial-in conferencing.

Use Communications Server Control Panel or Communications Server Management Shell to configure Conferencing Policy settings. Specify whether:

• PSTN conference dial-in is enabled.
  
  
• Users can invite anonymous participants.
  
  
• Unauthenticated users can join a conference by using dial-out phoning. With dial-out phoning, the conference server calls the user, and the user answers the phone to join the conference.

Configure dial-in access numbers

Use Communications Server Control Panel or Communications Server Management Shell to set up dial-in access numbers that users call to dial in to a conference, and specify the regions that associate the access number with the appropriate dial plans. The first three access numbers for the region specified by the organizer's dial plan are included in the conference invitation. All access numbers are available on the Dial-in Conferencing Settings Web page.

Note:
After you create dial-in access numbers, you can use the Set-CsDialInConferencingAccessNumber cmdlet to modify the display name of the Active Directory contact objects so that users can more easily identify the correct access number.
