Description

The conference bridge for Cisco Unified Communications Manager, a software or hardware application, allows both Ad Hoc and Meet-Me voice conferencing. Each conference bridge can host several simultaneous, multi-party conferences.
Software and hardware conference devices differ in the number of streams and the types of codec that they support. This course reviews major characteristics of Ad Hoc and Meet-Me conferencing, and software and hardware conference bridge implementations. This course also outlines general issues that can be experienced with conference bridges and explains how to troubleshoot them.
Cisco Unified Communications Manager invokes a transcoder on behalf of endpoint devices when the two devices are using different codecs and would normally be unable to communicate. When inserted into a call, the transcoder converts the data streams between the two disparate codecs to enable their mutual communication.
Finally, this course reviews major scenarios and considerations when a transcoder is used, it also reviews the codec selection process for Cisco Unified Communications Manager and voice gateways, and outlines general issues that can be experienced with a transcoder and explains how to troubleshoot them.
