A/V Calls disconnecting after a few Seconds RRS feed

  • Question




    I have an issue with A/V Calls. 


    My Current Setup is:


    1 Edge Server

    1 Front End


    Edge Server has 2 NICs with the following:


    Internal Interface: 10.x.x.23


    Access Edge Server


    Federation External:  10.x.x.33: 5061

    Remote Access External:  10.x.x.33: 443

    Internal IP/Port : 10.x.x.23: 5061


    Web Conferencing Edge Server


    External IP/Port : 10.x.x.35: 443

    Internal IP/Port : 10.x.x.23: 8057


    A/V Edge Server


    External IP/Port (TCP) : 217.x.x.103: 443

    External Port Range:  50000-59999

    Internal IP/Port (TCP) : 10.x.x.23: 443

    A/V Authentication Port:  10.x.x.23: 5062


    IM works internally and Externally.


    When making A/V Call the call rings, answers and then after approximately 5-10 secs disconnects.


    In the event Log i get the following error:


    Ms-client-diagnostics: 52031; reason="Call terminated on media connectivity failure"


    At present i have self signed certificates until the relevent checks have been complete on my requests for public certificates.


    Many Thanks

  • Are you doing federated calls?


    Is UDP 50000-59999 opened on the firewall protecting your A/V Edge server?


    We have had a simmilar issue and that required to update to the latest NIC Drivers and latest TCP/IP hotfix

    Many Thanks for your response Deli


    Will ensure these ports are available and report back.
