  • I would check a few items.  

    1) Do they have the same voice policy as you and other have?

    2) Can they simultaneous ring other numbers, can it simultaneous ring another internal user for example?

    3) Are other calls working normally for this user?

    If they have the same policy, but can't sim-ring others, then run the debug logger, start the IncomingandOutgoingCall scenario, making sure to check both the front end pool where the user lives and the mediation pool where the call should flow.  Reproduce the issue and stop the scenario.  Then check the logs using snooper to see what's happening to the simultaneously ringing number.  

    If they have a different policy, make it the same as yours, wait 15 minutes, log them out and back in (this isn't entirely necessary, but give it some time) and try again.

    If they can ring other numbers, just not the one they chose, it may be a problem with that number.  Try using the same number and setting up sim-ring from your account to see if you can get that line to ring.

  • Hi pumping_iron,

    Welcome to post in our forum.

    Agree with Anthony.

    You could go to SFB control panel to check the voice policy of the user.

    Please refer to


    As a supplement, you could try to clear SFB client cache by deleting the Lync User Profile and Registry Key.

    Here is a similar case for your reference


    Hope this helpful to you.
