Has anyone tried to changed the codec from G.711 to G.729 or vise versa via the registry entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\CVP\Customer\Voice Browser\Config\Codec "g711Ulaw64k"
If not, can someone that is running G.729 on CVP send me the g729 key entry?
Best regards and thanks in advance,
Troy

What do you mean, specifically?
Are you wanting to do your VXML prompts via g.729?
CVP does not support prompting or any other direct connection to CVP with g.729.
However, it is able to deliver the final call to the agent as G.729, if your call manager region settings dictate so.
Edit: Hitesh beat me to it while I was reading the SRND to verify my response.
Please see the CVP 7.0 SRND here.

It's not possible to change the codec on CVP VoiceBrowser to G.729
Using VBAdmin on the CVP server, you will see the following:
>>>>SetCodec /?
Type of codec and rate used in the voice browser when communicating with another VOIP endpoint.
Default: g711Ulaw64k
Valid Values: g711Ulaw64k or g711Alaw64k
System shutdown and startup necessary for changes to take effect.
ShowCodec /?
SetCodec g711Ulaw64k
Note: g.729 is not an option. If you try to set the codec to g.729, you will see the following:
>>>>SetCodec g729r8
The new codec value should be either "g711Ulaw64k" or "g711Alaw64k".
Hope this helps.

Thank you for the replies. I ended up sifting through the SRND's for 7 and 8 and I guess it was the latter one that I read last...
Release 8.0(1) of CVP supports a flattened deployment of the g.711 codec on all call legs, or else a flat
g.729 deployment on all call legs. A mixture of the 2 codecs on different legs of the call, at any point
in the duration of the call, is not supported.
I haven't been able to install 8 yet so, I guess that answers that.
Thank you
