Problem with conference participants


I have CCM 4.1(3), on which was configured conference bridge. Sometimes a few participants of conference take off from conference. I think this issue may be happen, because at this time in conference collect too many participants.

Therefore, I have following question:

1) How many participants of conference can simultaneously participate in one conference, if using software conference bridge;

2) How I can get the Log (debug) from CCM, where will describe cause of my issue.

Thanks a lot.


Re: Problem with conference participants

The Cisco Hardware Conference Bridge supports the Cisco Catalyst 4000 and 6000 Voice Gateway Modules and these numbers of conference sessions:

On the Cisco Catalyst 6000:

In a G.711 conference, there are 32 available streams; up to 10 conference sessions with three participants in each conference or one conference session with 32 participants.

On the Cisco Catalyst 4000:

In a G.711 conference, only 24 conference participants are allowed; a maximum of four conferences with six participants each.

For the Cisco Software Conference Bridge, the maximum number of audio streams is 128.

With 128 streams, a software conference media resource can handle 128 users in a single conference, or the software conference media resource can handle up to 42 conferencing resources with three users per conference.

If the Cisco IP Voice Media Streaming Application service runs on a different server than the Cisco CallManager service, a software conference cannot exceed the maximum limit of 128 participants
