IP Office Conferencing Capacity

IP Office provides a flexible conferencing solution with 28 conferencing channels on the IP500 and IP500 V2, allowing multiple conferences of any size from 3 to 64 parties. . This means that several conferences of different sizes can all run at the same time if the total calls do not exceed the systems conference resources. So the system will support 42 x 3-party conferences, 2 x 64-party conferences or any combination in between. IP Office does not impose limits on the mix of internal and external calls in conference, but if all internal participants disconnect from the conference bridge, the external participants can be disconnected automatically by the system for added security (configurable system setting).


1. Analog Trunk Restriction
In conferences that include external analog line calls, a maximum of two analog line calls are allowed per conference.
2. External Participants
Each external caller requires a digital trunk/VoIP channel (for example 1 T1 allows 23/24 external parties, 1 E1 allows 30 parties and a fully licensed VCM-64 allows 64 parties).
3. Use of Conference Resources by Other Features
System features such as call intrusion, call recording and silent monitoring all use conference resources, as does automatic recording if enabled. When any of these features are active the number of slots available for conference parties is reduced. For example, a conference call between 3 parties and being recorded will use 4 conference slots.
4. The IP500 Supports 128 Conference Members
The total capacity of the IP500 or IP500 V2 is 128-party conference resources. However the restriction of a maximum of 64-parties in any individual conference still applies.
5. Meet-Me Conferencing on IP500 requires Preferred Edition
IP Office 500 and IP500 V2 supports basic or ad-hoc conferencing, but if Meet-Me capabilities are required the Upgrade License to IP Office Preferred Edition should be purchased for direct dial into a conference bridge with PIN code security.
