HELP - conference problems

Unanswered Question
Aug 20th, 2008

Hi all dear friends, I have a CCM 4.1(3)sr7, a cisco 2650XM with 4DSP configured and an IGATE (for GSM network). The problem is when I try to initiate a conference with an IP Phone and 2 cell-phones (these two calls go through IGATE), the second cell-phone call is terminated, but if I use the software resources only I can establish the conference without any problem, but the intercluster calls, conferences between IP Phones is not possible any more.

Thanks a lot for any advise.

You may check the codec between all devices.

Check region settings for all devices involved.

As Gonzalo says check you codecs, keep in mind that Software Conference Bridge only supports G.711 so if you are using G.729 to talk with the cell-phone that could be the problem, you might need a Transcoder for this or a Hardware Conference Bridge.
