Hello everybody.
I have a CallManager 4.2(3) with h323 gateway. When I call from IP Phone through h323 gateway to PSTN, the codec is g729 I dont have configure any region only the default which use g711.
But when I call backwards from PSTN>h323gateway>IP phone the codec is g711 which is correct.
The IP Phones are on the LAN so I dont need to use the codec g729.
How can I force the calls from IP PHONE>H323GATEWAY>PSTN to use codec g711??
Regards

Hola Walter,
Check the dial-peer voip in IOS GW and configure either a voice class codec or hardcode the codec. (ie codec g711ulaw)
Since regions are already configured.

Hola gogasca thank for answering.
I already configure de codec g711aLaw on dial-peer voice XXX voip with target to the CallManager, because when I receive a call from PSTN>h323gateway>IP phone codec is g711alaw.
The problem is when I call from IP Phone>h323gateway>PSTN the codec is g729.
I dont know why, because I dont have any region configure on the CallManager.
And I have this problem with all IP Phones installed on the LAN.

Check which is your incoming dial-peer...
Do a show call active voice brief...to find out...

Hello gogasca thank for your answer
I check as you wrote the incoming dial-peer,
and I found my problem I have added a new dial-peer in order to receive calls from PSTN to Cisco Unity.
I just adjust the codec g711aLaw and It works.
Regards.

Hi Walter,
You have stated "I have added a new dial-peer in order to receive calls from PSTN to Cisco Unity" an you have adjusted that.
Then when you make a call from IPPhone to PSTN, it uses this dial-peer, I would suggest you to have different dial-peers for specific patterns in your setup.
