I have a customer with following solution:
1 Lync Front-End
1 Lync Edge
1 TMG Reverse proxy
3 external IP (sip, webconf, av)
Edge server are placed in a DMZ sone, with 3 network ip in DMZ and 1 in local network. I have used Joakim Silverdrake blog post for Lync and TMG.Joakim Silverdrake Blog
Customer has same internal and external domain name.
Problem:
Federated users cannot make AV calls to my customer Lync users, but can see precense and make IM conversation. Whiteboard also works.
AV conference with 3 users from my customer Lync SIP domain works as normal. (with external and local users)
OCSTestconnectivity with AV = OK
Logging:
I have tried to log the problem with Lync Logging Tool and Snooper on Lync Clients. Also Logging Tool on SIPStack on Edge server.
On Lync Clients i get the following message:
After ACK message, i get an BYE sip:user@federateddomain.com and connection is broken. And only error message i receive is "A federated call failed to establish due to a media connectivity failure where both endpoints are remote"
SIPStack on Edge server is blank in Snooper.
Hope anyone can guide me to a solution for this problem.
