I have a CallManager 7.X running on the Cisco MCS-7845 platform. My question is how many internal conferences are supported with this platform?

Correct Answer by Steven Holl about 6 years 10 months ago

Are you talking about the amount of conferences using the software conference bridge directly on CM?  If so:


Cisco Conference Bridge Software

Software conference devices support G.711 codecs by default.

The maximum number of audio streams for this type equals 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.


Caution If  the Cisco IP Voice Media Streaming Application service runs on the same  server as the Cisco CallManager service, a software conference should  not exceed the maximum limit of 48 participants.

If you have hardware conference bridges (IOS-based) then the limit is based upon how many sessions you have confiugred under your conference bridge DSPfarms.

The included SW CFB supports up to128 streams.


How many conferences depends on the value for these CUCM parameters:


Maximum Ad Hoc Conference
Maximum MeetMe Conference Unicast


How many conferences you can have is

128/ above parameters = # of concurrent conferences for each type.
