[cisco-voip] IOS conferencing question[bcc][faked-from][html-rem]

You can see that on the gateway, by typing 'show call active voice brief".

BTW, call manager's g729 allow all the flavors of g729, it is up to the endpoints to agree on what codec will they use, now since the ios gateways will default to g729r8 on their voip dial-peers, that would most likely be the selected codec.

How would I see this is the case?  Traces in CCM?  Debugs on the gateway?

Okay.  Let me rework that question.  When I select g729 in Callmanager
what version of g729 is actually used?

You should not use g729b at all in your network. This is because VAD is
enabled in this codec. It can't be disabled with using g729b.

We have 3845 routers with NM-HDV2 modules at each site to support local
PRIs and conferencing.  We have PVDM-64 installed on the HDV2 modules.
I am setting up conferencing on the routers and I want to eliminate
unnecessary codec from the list of codecs supported.  We use 7960 and
790x phones.  Callmanager is configured for calls over the WAN to be
g.729 and we use g.711 internally to each office.   A user at any site
can envoke local conference resource to conferenc PSTN calls,  local
phones and phones located across the WAN.

I can leave the following config but it wastes DSP resources:

dspfarm profile 1 conference
 description office Conference 1
 codec g711ulaw
 codec g729r8
 codec g711alaw
 codec g729ar8
 codec g729abr8
 codec g729br8
 associate application SCCP
 maximum sessions 4

What can I remove from the codec list?

Thanks,

Pete Ruttman
