ABSTRACT:
A method and apparatus for providing a capability for placing a slight delay in processing call setup and termination signaling messages in conferencing applications so that the call processing rate requirement on a Call Control Element (CCE) is lowered. For example, allowing conferencing participants of a conference call to join a conference bridge over a 90 second period will significantly improve the processing load on the CCE than allowing them to join in over a 30 second period. In one embodiment, the present invention introduces a configurable delay in the processing of signaling messages for call setups and terminations for high volume calls onto conference bridges.
