Dear All,
We have Expressway Series (C&E) clusters connected with CUCM and CMS servers and we have multiple Video endpoints registered as MRA as well as native registration to CUCM over LAN / WAN. We are calling to Webex Cloud via DNS zone as a B2B call from registered endpoints.
Now we have a new business case where in we are required to call one of our partner organization which are on their own Cisco Collaboration platform and separate SIP domain, as a B2B calls, not on internet but on a dedicated MPLS network due to compliance reasons.
What are my options to achieve this solution. Please I need your suggestions and recommendations
Expressway = 12.5
CMS = 2.8
CUCM = 11.5

Is the sip domain resolvable from the mpls network?

Cisco had a lot of docs on setting up B2B via Expressway. Here is just one:
Configure Business to Business Audio and Video Calls Through Expressway Integrated with CUCM
Also, on dCloud the Cisco Preferred Architecture for Video 11.5 v1 lab has a module where you can practice setting it up.
