Conferencing Resources


A very usual question from people is, how many conference can I have, and how many parties can join a conference. Let me summarize below:

For Single-mode conference (G.711)
- PVDM - maximum 6 parties per conference
- ISR/PVDM2 - maximum 8 parties per conference
- WS-X6608 - maximum 16 parties per conference
- IPVMS - maximum 48 parties per conference
- CMM/ACT - maximum 64 parties per conference

For PVDM2, max 8 parties are allowed per conference, and 8 conferences are allowed per DSP. For using IPVMS in CUCM, maximum 48 parties are allowed per conference.

These are all G.711 values.

For example, if I have a PVDM2-16 = 2 DSPs = 2 x 8 conferences = max 16 conferences x 8 participants = 128 conference parties.

Max no. of conference per domain is 50 with 400 participants because of HW / IO limitation.

For mixed-mode conference (G.711 + G.729a)
- 2 conferences per DSP and 8 participants per conference.
