what's required to create encrypted trunk with Cisco call manager

Dear All,

I need to create a new TLS trunk between Lync 2013 and Cisco Call Manager, i would like to ask about the requirements, usually when i do TCP trunk, nothing required, only the same port in Lync and Call Manager, but using TLS is it the same?

Please Help

Please see the link from Microsoft below, it describes how to configure appropriate security via TLS

Set SIP Trunk Security Profile Information
In the SIP Trunk Security Profile Information section, specify the following settings as shown in figure 15:
•      Set Device Security Mode to Encrypted. This ensures that CUCM uses TLS to communicate with the Mediation Server.
•      Set Incoming Transport Type to TLS.
•      Set Outgoing Transport Type to TLS.
•      Set Incoming Port to 5061.

Hi,

On Lync Server side, on topology, you need to choose TLS protocol instead of TCP. Then also, you need to use the same port for Mediation Server and the port on PSTN gateway.

Note that you need to make sure the PSTN gateway support the TLS protocol.
