I ahv an OCS R2 STD deployment that includes an Edge Server and an FTMG server. The issue I am having is with external Audio and\or Video connections. Internal connections work fine. I ahve tested an Externally signed in user to an internal user and also a federated to internal user, both fail.
I have checked ports and all teh things I can think of. the following are errors I am seeing:
On the FE server
OCS Protocol Stack 1001 14502
A significant number of connection failures have occurred with remote server <edgeservername>.<company>.net IP 172.xxx.xxx.xxx. There have been 207 failures in the last 180 minutes. There have been a total of 8186 failures.
The specific failure types and their counts are identified below.
Instance count - Failure Type
This can be due to credential issues, DNS, firewalls or proxies. The specific failure types above should identify the problem.
and when I run the A/V validation on the FE:
Connecting to A/V Authentication Edge Server to get credentials A/V Authentication Edge Server: Could not contact A/V Authentication Edge Server.
To resolve this error, check for the following
1. The outbound proxy is reachable.
2. The outbound proxy and A/V Authentication Edge Server are in trusted server list of each other.
3. The outbound proxy and A/V Authentication Edge Server have valid certificates.
4. Conference Server certificate is valid.
5. A/V Authentication Edge Server Gruu is correct.
[0xC3FC200D] One or more errors were detected
validation on the Edge returns no errors.
There is not a firewall between the edge and FE servers.
Suggestions of items to check?
I looked at the FE\Global properties\Edge servers and it shows the fqdn and 5062. the edge server has A/V authentication port set to 5062.
