Voice data flow in Fowrading/Redirect call? RRS feed

  • Question

  • Hi all,

    I have a question Voice data flow in Fowrading/Redirect call?

    Scenario is:

    Number A (from PSTN network) ----call to----> nunmber B (Lync number)

    B  ----forward/redirect call----> number C (in PSTN network)

    I am wondering about when the call between A & C is established. B is not related to the call anymore, isn't it. So does the voice data continue to pass through Lync Server anymore?

    I am not sure about the how to calculate fee for the call, assume that number A belongs to the Provider A, number B belongs to the Provider B...

    Thks for reading,

  • Well that depends completely on your PBX / Gateway or SIP Trunk whether they support the REFFER option.
    Look at your TRUNK configuration in Lync and verify REFFER.

    You can do SIP tracing on the Mediation Server to verify behavior.

    If REFFER is not enabled then Lync uses 2 Call Legs and bridges both streams

  • Hi Johan,

    Connection between Mediation Server and CUBE (or Cisco Voice Gateway) uses DIRECT SIP, not trunk connection

    CUBE (or Cisco Voice Gateway) was configured to connect to the PSTN network directly

  • I am referring to configuration you need to do on Lync not Cisco : Trunk Configuration
