deploying transcoders between two CME routers

Unanswered Question
Mar 19th, 2009

Dears,

i am trying to deply transcoders on two cme routers, to permit the forwarding of unanswered or busy lines to voicemail. On the voip dial-peers between the branches i am using a g729 codec.

So i configured transcoders on both routers and i verified that the transcoders are registered to the CME routers but it seems that any call from the other branch is still forwarded to the unity express without being transcoded to g711. The following is the transcoder config on the first router:

voice-card 0

dsp services dspfarm

sccp local GigabitEthernet0/0

sccp ccm 192.168.101.50 identifier 1 version 3.1
