Conferencing and transcoding resources

Hi..

would like to check, if i have the following configuration

dspfarm profile 10 conference

description Conference Resource

codec g711ulaw

codec g711alaw

codec g729ar8

maximum sessions 8

associate application SCCP

The max. sessions is tied to the codec complexity used. In this case, the medium complexity G729A. Would like to check if all 8 calls are using G.711, can the 9th G.711 calls still join the conference ? I think it is possible because G.711 is of lower complexity.

Can someone confirm ?

Re: Conferencing and transcoding resources

A conference based on C5510 DSPs allows a maximum of 8 participants. When a conference begins, all 8 positions are reserved at that time.

A DSP farm configuration in Cisco IOS specifies which codecs may be accepted for the farm. A DSP farm that is configured for conferencing and G.711 provides 8 conferences. When configured to accept both G.711 and G.729 calls, a single DSP provides 2 conferences because it is also reserving its resources for performing transcoding of streams.
