A/V Calls disconnecting after a few Seconds RRS feed

  • Question

  •  

    Hi,

     

    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.
