We are unable to establish PC-to-PC calls through the Edge Access Server to external clients. The AV session appears to be trying to connect, but sits at the Call Connecting screen for roughly 10 seconds before it states Call Disconnected. I have found the following in the OCS Server and Office Communicator logs both state: Ms-client-diagnostics: 52031; reason="Call terminated on media connectivity failure". Has anyone resolved a similar issue?
Note: We are not using a mediation server as this is strictly for PC-to-PC calling at this point. And the pool is pointed to the internal FQDN of the edge server at port 5062; while the server in the pool is listening on port 5063.
