Expressway C and Lync Interop

[Seifeddine-Tlili]

Greetings Experts

we are in the process of integrating Video between CUCM and Lync, therefore we are using an Expressway C with B2BUA

Few items came up from the deployment guide:

Seems like we can only use TLS on B2BUA since it can`t be listening on TCP (when we disable SIP TLS globally , the system complain that it`s now disconnected from the B2BUA service, can someone confirm this?

also for CUCM/VCS integration , does it need to use TLS? if so , can we just use the self signed certificate on CallManager/Expressway C for this purpose?

Thanks

Hi,

Page 28 of the following CUCM with VCS deployment guide provides details of the TLS and certificate requirements

http://www.cisco.com/c/dam/en/us/td/docs/telepresence/infrastructure/vcs/config_guide/Cisco_VCS_Cisco_Unified_Communications_Manager_Deployment_Guide_CUCM_8_9_and_X7-2.pdf

It does mention that TCP can also be used.
