  • It looks like you got an access denied error (0x80004005) when starting AV. Can you detail a bit more on what you are trying to do?

     

    Perhaps the meeting policy assigned to the "presenter" of this meeting lacks the rights to launch IP Audio and IP video? Can you check this?

     

    Look here for more info:

  • Did you get this issue resolved?
    I'm having the same problem when Live Meeting connected via Edge server, can't start A/V stream, getting exactly the same error code..
    Internally (OCS SE server) Live Meeting A/V works fine.

    Source: OCS Audio-Video Confer   Event ID: 32018
    The Audio-Video Conferencing Server encountered an error when requesting
    credentials from the A/V Edge Authentication Service.

    A/V Authentication Service Service URI
    sip:computer.domain.com@domain.com;gruu;opaque=srvr:MRAS:nk3O1_NRh0WvvnPDTuuingAA, Reason: The requested operation failed.
    Cause: The Audio-Video Conferencing Server cannot communicate with A/V

    Resolution:
    Check the A/V Authentication Service is alive and that network connectivity
    exists.

  • See amsi658 above.   The rtcproxyservice user must be english.  
    Please reply back if you still experience the same problem after changing the default language

  • I am currently experiencing the same behavior when attempting an external A/V conference.  The link above mentions the default language issue that MS has solved in the April updates. ( and have applied all updates available to R2 (including KB967831).

    Has anyone found a solution for this issue?

  • In my case I made a mistake in configuring A/V Authentication Service setting on OCS server.

    My A/V Edge Server uses default ports.

    In OCS Server Global Properties -> Edge Servers -> A/V Edge Servers when you add Edge Server "A/V Authentication Port" should be the same as "A/V Edge Server TLS Signaling Port" (but NOT "A/V Edge Server Internal Interface Port") on your Edge Server. To see that you need to run Deployment Wizard on your Edge Server and run "Configure Edge Server Wizard".
