Can RoundTable Bridge a Live Meeting call with a PSTN call ? RRS feed

  • Question

  • Hi,

    I have a roundtable connected to a laptop and works well (I am USER1). I initiate a LM call with another remote laptop user, so VOIP is used (User2). That works well.
    I then use my roundtable to dial another user's phone using PSTN and that works too (User 3).
    User 1's voice can be heard by both User 2 & 3.
    User 3's voice (PSTN) can be heard by Users 1 & 2.
    The only thing I cannot get working is User 2 (LM VOIP remote user with no roundtable) can be heard by Roundtable user but NOT the PSTN user.
    Why ?
    Bridging seems to work well in one direction by Roundtable but not the other.

    Anyone able to help ?

    Cheers

    Ish

  • Hi Ismayeel,
    Bridging local dialing from the device with OCS calls is not a supported scenario. The device has no local mixing capability.
    What you need to do is implement OCS MCU, incl. PSTN connectivity through a GW, provision the user as EV enabled, and dial out from the organizers's OC to the PSTN participant.
    There could be licensing implications.

  • Hi FD,

    Thanks for the reply.

    However, it is interesting that th Roundtable device is happily mizing the PSTN user's audio in to the VOIP discussion.

    So, if we take whats happening right now and combine it with what you are saying, then it seems that PSTN->VOIP mixing is supported but not VOIP->PSTN.

    Weird.

    Thanks.
