As of Right now we can only initiate 4 calls using the conferance feature, is there a way to increase the number of people that can be on at the same time?
Yes. In the Call Manager service parameters you can modify the "maximum ad hoc conference" parameter. From the online help:
This parameter specifies the maximum number of participants that are allowed in a single Ad Hoc conference. The value of this field depends on the capabilities of the software/hardware conference bridge. The maximum number of conference bridge participants for typical conference bridges follow: Software Conference 64; Cisco Catalyst WS-X6608: 16; Cisco Catalyst 4000: 16; and NM-HDV: 6. Setting this value above the maximum capacity of the conference will result in failed entrance to a conference bridge if you try to add more ports than the specific conference bridge configuration allows.
This is a required field.
Note that with later ISRs/IOS, I believe you can get 8 parties in a single conference.
This has been asked PLENTY of times before, please search NetPro for answers before posting.
