I have a strange problem with a CM 4.1. Internal conferences work fine, but when there is a conference with two external participants, one of them disappears after about ten minutes. If he stays on the phone he will return to the conference after about 20 seconds. During this time he hears some strange noise. Normal calls over the gateway work fine, this only happens during conferences. The gateway is a 2821 (MGCP) with an E1 PRI interface. Does anyone know what causes this problem?
yes it happens to all conferences with external participants after about ten minutes. It is always the exrernla participant who disappears. The dsp resources should be fine, the gateway has 64 and is only using 34 by its voice interfaces. I will try to have a look at a trace while this is happening
