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.</SPAN></FONT><o:p></o:p></P>
