Conferencing
The Catalyst 4000 DSPs can only support G.711 conferencing sessions.This
is not to say that there can be a conference session on a Catalyst 4000 with only
G.711 participants, but that transcoding DSP resources must be involved to convert
those participants to the G.711 CODEC for the conference.The Catalyst
4000 AGM module supports up to 16 transcoding sessions per module via hardware
and would handle up to 104 channels in software.
