Add Mailbox and Client Access servers to a SIP URI dial plan in Exchange Server

Applies to: Exchange Server 2013, Exchange Server 2016

You can add Client Access and Mailbox servers to SIP URI dial plans. Client Access and Mailbox servers can't be associated with Telephone Extension or E.164 dial plans, but the servers will answer all incoming calls.

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.

For additional management tasks related to UM dial plans, see UM dial plan procedures.

This example adds the Mailbox server named MyMailboxServer to a SIP URI dial plan named MySIPDialPlan and prevents it from accepting new calls. It also sets the startup mode to Dual mode, which enables the Mailbox server to accept TCP and TLS requests.

Set-UMService -Identity MyMailboxServer -DialPlans MySIPDialPlan -Status Disabled -UMStartupMode Dual

This example adds the Mailbox server named MyMailboxServer to two SIP dial plans, named MySIPDialPlan and MySIPDialPlan2, and sets the following:

• Allows both IPv4 and IPv6 addresses.

• Sets the maximum number of incoming calls to 50.

• Configures the SIP access service for Lync Server.

Set-UMService -Identity MyMailboxServer -DialPlans MySIPDialPlan, MySIPDialPlan2 -IPAddressFamily Any -MaxCallsAllowed 50 -SipAccessService northamerica.lyncpoolna.contoso.com
