Problem doing a MOC to MOC voice call with federated partners ONLY RRS feed

  • Question

  • I everyone,

    I have OCS R2 : Standard Edition and Consolidated Edge R2 Topology.

    EVERYTHING works execpt when I try a MOC to MOC to our federated partners (Microsoft is one example)

    I get this error on my R2 client:
    "Call was disconnected"  : (The call was disconnected because you stopped receiving audio from USERNAME. Please try the call again.)

    Chat works, Web conf works,  and I am able to MOC call external domain users.

    Only the Fderated partners that does not work....

    Thanks for any help

  • All of our servers are already setup with English (US) regional settings.

    Any other ideas.

    PS: we are not using any NAT on our Edge.

    Here is a snip of a OCS  Logger:

    MOC to MOC voice call works when users are External:  External user calls a federated MOC.
     But when internal users tries to voice call an Federated MOC...it does not work??

  • Hi JP,
    What was the solution finally ?
    did you modify some settings on your edge server ?

  • There was a port : 3478 UDP that was not open on the firewall.

    Hope this help
