Lync and PBX call authentication RRS feed

  • Question

  • Hi I have a PSTN Gateay and IP/PBX.

    User A has Lync client and PBX Phone (Intercom)?

    Now a call comes for an User A from outside, It is ringing in Lync client as well PBX phone. My question is now,

    Is it get routed from Directly PSTN Gateway to Legacy PBX Systems? then how user will get authenticated in Lync (for ringing in Lync client)?

    or Is it get route from PSTN Gateway to Mediation server (Gets authenticated) and then again goes to PSTN Gateway (Transist media for Legasy PBX phones)  -> connects to Legacy system (using routing configuration) and then PBX Phone?

    which one is above will works? or is it something different from above?



    Thanks

  • Typically, I'll have the call route to that PBX and fork or simultaneous ring back to Lync if possible.  However, you could potentially set it up the other way around so that the call is first received by Lync and simultaneously rings the PBX phone (through a dummy number or some other method).

  • Hi,

    You can refer to the following situation:

    Enterprise Voice Behind the PBX

    When Enterprise Voice is deployed behind the PBX, all calls from the PSTN arrive at the PBX, which routes calls to Enterprise Voice users to a PSTN gateway, and calls to PBX users to the PBX.

    Enterprise Voice in Front of the PBX

    When Enterprise Voice is deployed in front of the PBX, all calls arrive at the PSTN gateway, which routes calls for Enterprise Voice users to Lync Server and calls for PBX users to the PBX. Calls to the PSTN from both Enterprise Voice and PBX users are routed over the IP network to the most cost-efficient PSTN gateway.

    Best Regards,
