Echo Cancellation Support for Media Server Conferencing

Distributed conferences, a feature that was released in CIC 4.0 SU4, added the ability to scale conferences to nearly unlimited numbers by incorporating multiple media servers in a single conference. With this conferencing improvement also came the need to improve the signaling and overall conference experience. Previously, letting the endpoints do the signal conditioning and echo canceling was enough. Increasing the size of the conferences also increased any signal issues as well. To enhance the call quality of conferences, SU5 adds echo cancellation and other configurable improvements. Echo cancellation is disabled by default. To configure this feature, refer to the Interaction Media Server Technical Reference in the CIC Documentation Library.
