Answered Lync Federation / EDGE issues with Voice/Video

    Hi all,

    We have a full running environment with FE STD en EDGE (DMZ), everything works (External access, Video/voice, Telephony, everything internal/external) except Video/Voice with federation...

    The federation works for IM/Presence but no AV...

    We have tried already to monitor traffic on the firewall and the only thing we are seeing is that the incoming connection from the federated user is going to the wrong ip address for port 3478 (the SIP access public IP instead of the AV service IP) and is dropped (because there are no NAT rules on the SIP public ip for 3478).

    Has someone any idea why the connection is going to the wrong IP address? Topology builder has the correct settings...

    Any help would be welcome!

    FYI, we applied this settings on the firewall:

     

    Thanks

    MVK

    Hi,

    Any possibilities to get both Communicator uccapi loggings - the federated account & your Lync users? Upload it to Skydrive and I'll have a look at it. Try to get a logging at the Access Edge server would be useful as well.

    Probably a ridiculous thing but could you confirm whether the NAT IP address are correctly mapped? Assuming each services above is having its own public IP address and it is mapped to the correct internal IP of the Access Edge external interface.

    Hi ,

    Few questions here;

    • Does audio/video call fail across federated partners or any specific partner ?
    • Are you able to make AV calls between external cor user (internet/home) and internal user (with in office network) ?
    • Can you schedule a Lync online meeting and send it to federated partner and check the AV connectivity (When they connect the Lync-online link, try to capture the traffic on your firewall) ?

    Thanks

    If you see the Port 3478 hitting the wrong IP, check you av.sipdomain.com is pointing to the correct Public IP and NAT'ed to the correct DMZ IP. The topology edge configuraiton has the filed for NAT'ed IP, this should be the Public IP for your AV role, not the Access or Webconf. If you send a packet form your AV interface, it should be providing the Public IP for this interface in the packet (1:1 NAT).

     

    Thanks,

    Jeff

    Hi,there,

    Agree with Jeff,hitting wrong IP is probably caused by incorrect public IP defined in the "NAT enabled public IP address used" in the properities of Edge server in the topology,you can change it to the correct A/V edge public IP address and republish the topology.

    Regards,

    i have the same issue. howerver i am using a single fqdn and ip address for my sip, web conference, and A/V service

    the only question is mhy sip port (5061) is the same as the federation port

    when i did packet capture i see that the edge server is trying to communicate to the actual ip address of the remote (federated client) instead of the public ip.

    i am wondering if it has to do with any alg setting on the firewall
