You have an Exchange Server organization that contains five servers. The servers are configured as
shown in the following table.
You deploy Microsoft Lync Server 2010. You need to create a Lync Server SIP Unified Messaging
(UM) dial plan to enable voice integration between Lync Server and Exchange Server.

B,E- 100% – If you’re deploying Microsoft Lync Server, to enable outbound calling to work correctly, you must manually add all Client Access and Mailbox servers to all SIP URI dial plans that you’ve created for Lync Server.

Add all Client Access and Mailbox servers to the SIP dial plan. To enable the server to answer incoming calls, you must add all Exchange servers to a dial plan if you want them to answer calls from Lync Server.
