Hi all, do somebody know, how many conference connections can be used on 7835 MCS server with CCM 4.2? I dont have transcoder, but I think that server alone can mix some conferences. If you know link it would be nice. Cannot find on cisco.com even if I tried. THX

Hi Thomas,


These number are for the Software Conference Bridge available on CCM :)


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.



From this good doc;


http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/4_1_3/ccmsys/a05confb.html#wp1035397



The default number of Maximum MeetMe Participants (per Conference) is set at 4.


To increase the Maximum number of MeetMe participants (we have ours at 16);


Go to:


Service Parameters Configuration >Clusterwide Parameters (Service)>Maximum MeetMe Conference



Here is some additional info;


Conference Bridge Configuration

With the Software Conference Bridge;


128 Streams


128 with 48 Users in each = 3


128 with 24 Users in each = 6


128 with 16 Users in each = 8


128 with 8 Users in each = 16


128 with 4 Users in each = 32


Hope this helps!

What dictates the number of users you can have in each conference? Are those numbers you posted for configured MeetMe patterns or are they for live conferences?


I just had an issue where I had 1 live conference and couldn't get more than people including the conference controller on the conference. When I tried to join the conference while doing a reactive debug with my IPCC MeetMe script it just kept me on hold and wouldn't allow me to join the conference.


I just tested it again on the side and I would get a fast busy with the 7th join attempt.

Hi Brian,


Both Ad Hoc and MeetMe conferences have a configurable setting that limits the number of participants;


Clusterwide Parameters (Service)


Maximum Ad Hoc Conference = 4


Maximum MeetMe Conference Unicast = 16


Hope this helps!

I updated that entry from 6 to 16 and now the most I can get on a single MeetMe conference is 8 including the conference controller. Any ideas?


Thanks
