Conferencing Attendant issue RRS feed

  • Question

  • Hi,

    I have 2 issues with my conferencing attendant. I have configure a dial-in access number in my Cisco Call Manager. When I call this number, it forwards it to the SIP associated with my conference bridge. I then ear the message to put my meeting  ID, I do so and I get connected to the meeting.

    First Issue: While I am connected to the meeting, if someone else is trying to dial-in, they get a busy tone. What if someone else is hosting a meeting, they should be answered by the attendant to get to that meeting? Can the attendant receive more than one call? Do I have to create more than one dial-in numbers?

    After the meeting, I hangup or get kicked from the meeting and close the line.

    Second issue: IfI try to reconnect to a meeting, the attendant is not answering the dial-in line anymore. If I call, I get disconnected as soon as I get transfered to the Lync SIP. If I log into the Lync server and restart "Lync Server Conferencing Attendqant", it works again for 1 time. Why is the attendant not functioning after a meeting?

    Any input would be greatly appreciated.

  • You can call the dial-in conference so often you want. It Looks like a configuration problem.

    Are you sure that the configuration on the cisco call Manager is correct. Try to configure a TCP SIP Trunk to lync and use wireshark to debug the call flow.

    We use the Dial in conference most of the time with more than 20 Persons without problems, but we use a Certified Media Gateway.

  • Hi,

    Can you get some logs about this problem on lync servers?

    You can run Lync server 2010 logging tool on lync mediation role server, check S4, Siptrace, mediationserver option and get the logs when you reproduce the problem.

  • It sounds as though the SIP trunk from CCM is restricted to a single channel - so less like a SIP Trunk and more like a SIP endpoint.

    I have had this configured for conferencing in exactly the same way before and so long as CCM is set to terminate a SIP trunk into Lync then all you need is one phone number which will handle as many users as connections that CCM will allow.

    Hope this helps
