[cisco-voip] Nm-hdv and conferencing

[Ruttman, Peter G.]

Folks,

We've been using the nm-hdv cards for awhile and we were just asked how
many participates we can support in a conference.  Checking out the
documentation it looks like we should be able to support 6 people in the
conference on this type of card.  I tested it out on one of our systems
and I can only get 4 parties in total on the conference call.  I get the
message "Exceed maximum parties" on the phone when I try to add the 5th
party.

I then built up the same configuration in the lab on 4.1.3 and got the
same results.  We use G.711 Regions.  On the call manager side I am
using a Cisco ISO Conference Bridge.  Here is some of the configuration
from the 3745 voice gateway:

sccp local FastEthernet0/0
sccp
sccp ccm 10.8.1.4 priority 1
sccp mtp sessions 10
!
dspfarm confbridge maximum sessions 5
dspfarm rtp timeout 60
dspfarm connection interval 60
dspfarm
!

Any guesses on why I am being limited to 4 participants?

Pete
