"Join conference call now using Lync Call" fails RRS feed

  • Question

  • When my users attempt to join a conference call by clicking the link in Outlook and then prompting for Lync to call them using Lync Call the they get an error that displays in a yellow bar across the bottom of the Lync client that says the "Call was not completed or has ended." If you click on this error, a pop up screen appears and says "When contacting your support team, reference error ID 399 (source ID 244)." I can't find anything in the server event logs or snooper that point me anywhere near the right direction. What can I try?

  • Hi Pburk,

    Did the issue happen only for external users or for all of the users?

    1. Please try to join into a meeting directly using Lync client with the option Meeting Now, if it works well then the issue may cause by Outlook.
    2. Remote conferencing features are supported by the Web Conferencing Edge service and the Audio/Video Edge service. The traffic goes through Lync Edge server use other Lync client except Lync Web App. If you use Lync Web App, all the traffic goes through reverse proxy. You can use Lync Web App to join the conferencing, if it works, there may be some problem with Edge Server. It you fail to join the conferencing, you have to check the reverse proxy is configured correctly.

    Best Regards,

  • Not external users, do I need an edge server for ANY voice conferencing at all?

  • So, there is no edge deployed.  Does peer-to-peer audio work?  Is there any firewalling on the server, or clients that may be blocking access?  Finally, what A/V is in use and does it block or inspect any network traffic or just file access?

  • Peer to peer audio WAS working, it is not right now just to tweaking different settings. There shouldn't be any firewall problems, I don't see anything in the logs on the ASA that would suggest that. We are using Symantec.

  • Peer to peer should be just that, audio media sent between two clients and not needing to touch the server.  If you don't see an issue in the snooper logs on the server, I'd start checking programs that may inspect or interfere with client network traffic as Symantec Endpoint Protection can.

  • Hello,

    What version of Symantec Endpoint Protection are you running?

    With regard to the exclusions to be made in Symantec Endpoint Protection for Lync folders:

    Microsoft has a document called Specifying Antivirus Scanning Exclusions

    http://technet.microsoft.com/en-us/library/gg195736.aspx

    In addition, firewall rules need to be configured to allow Lync to function; Microsoft has a document detailing the ports in use by Lync:

    http://technet.microsoft.com/en-us/library/gg398798.aspx

    Hope that helps!!
