[cisco-voip] CallManager 4.1 and ACT Card on CMM Module

[Jose Mujica]

Hi.

 I'm having a problem and would like your inputs. I have an ACT Module in a
Cat6k CMM Module running 12.3(8)XY2. I have configured the mediacard for
conference resources for G711 and G729 codecs. I have also configured the SCCP
and DSPFARM for the conference resources and associate all the configuration
all together.

 On the CCM I have created a hardware conference resource using the IOS
Enhanced Conference Resource and the device shows up as register on
callmanager and connected on the CMM Module. The client currently has a
central site and a remote site and regions has been configured to use G729
over the WAN. The CMM module is at the central site. When a conference bridge
is initiated using the ACT dsps I don't have 2-way voice on all 3 IP Phones (2
central site and  1 at the remote site). On the CAT6k I can see the sessions
with the show mediacard connected command but I only have 1-way audio. 

Any ideas? Below is the config for the ACT card and show commands:

The IP Address 172.16.56.34 is the IP Phone across the WAN and the
172.16.55.12 is the IP Address of the CallManager. I'm using the IPVM service
for conference right now and using the ACT for transcoding. The conference was
initiated by the remote ip phone and 2 IP Phones from the central site were in
the conference. They were able to talk to each other but i was unable to hear
them and viceversa. I also tried to configured the ACT for conference
resources but when I initate the conference from the remote ip phone I
received a fast busy signal.

Here is the relevant config on the CMM for the ACT card:
