in order to join 2 different call leg (sip & h323) with g729 codec, i think
transcoder (MTP hardware)is a must. MTP software can do this but only for g711
codec.

That;s what I am trying to find out if I need the Xcoder. I think if
I've xcoder the call would work even w/o ipip gw. Is Xcoder must in
this scenario?
Thanks for your time...

try to terminate your call from CME to IPIPGW (w/transocder) on HQ router,
don't direct to CCM. so the topology will looks like this
IP Phone -- CME -- SIP/H323 Trunk -- IPIPGW -- SIP/H323 trunk -- CCM -- IP Phone

Hi,
Following scenario:
IP Phone ---CME---sip trunk---CCM--IP Phone
Using g729 call fails and works fine on 711. MTP is selected on trunk, infact
I've created an IOS enchanced software MTP on a router and given it to SIP
trunk. Bt that's software only and I understand it would support only G711.
Tried with CCM SW Mtp but same result.
Can pl comment if that's the case why calls are failing on 729 or what might
be missing.
SIP dial-peer config:
!
dial-peer voice 9 voip
destination-pattern [1-2]...$
session protocol sipv2
session target ipv4:10.5.0.1
dtmf-relay sip-notify
codec g711ulaw
no vad
Thanks for your time..
