    I have a customer with a Lync 2013 on premiss environment. Users are Enterprise voice enabled and there is a interoute SIP trunk. Some users report that sometimes when they are called on there phone number the do not receive the calls.
    When i check the Lync Monitoring reports a see the error message bellow.

     ==========================

    The time between the 2 alerts is exactlly 20 seconds, the default time for a disconnect when the call is not answered.
    Anyone has an idea why the calls are not routed to the Lync user?

    Best Regards,

  • According to the error, it seems that the Lync user signed in on multiple endpoints. You should check that.

    Please also check the receiver’s phone number is not assigned to other user.

    You can use the following blog to check who uses the specific number.
