CME does not utilize PVDMs for conferencing, it mixes the streams via software conferencing bridging, hence you can only have 3 participants per conference.

cderen, i have a question. 3 participants per conference is that the software limitation?

i have 4 FXO port on my ISR2821, using CCME 4.1. My requirement would be 4 external call from PSTN calling in, for a 5 person conference. When we are in a 3 party conference and we tried to dial a 4th party(PSTN), the call is disconnected

What would i need to accomplish that? i tried configuring DSP..but im getting no where with that. Plz advise
