P2P call on the same network and loss of Lync connectivity RRS feed

  • Question

  • On a Lync 2010 system, if an internal call (P2P) on the same data network is taking place and the FE server fails, connection to the FE server is gone, or the server is turned off, will that internal voice or video call stay up or will it drop immediately? Thanks.

  • It depends. I am pretty sure that if the call has already been established then it should remain up and running as the media stream is only between the clients and no further sip signaling is required. Same goes for PBX calls if you have media bypass enabled. However, presence and user lookup will not work, and neither will trying to initiate any new sessions (eg. adding sharing to the existing call, adding users to the call, making new calls, etc.)

  • Yes that is correct.

    This is also correct if its an Enterprise server and the backend SQL goes down. (most people tend to forget that the Back end SQL is equally important to the front end in a Enterprise setup)

  • It would stay up but new session will not work.
