Cisco 7970 and the G.722 codecThe G.722 codec is disabled by default on the 7970G phone. - To enable the G722 codec, add the following line inside of the <vendorConfig> context: <g722CodecSupport>2</g722CodecSupport> - Add the following line within the <device> context: <advertiseG722Codec>1</advertiseG722Codec> On a config generated by CUCM 6, the 'advertiseG722Codec' context usually appears on a new line following the <encrConfig /> context. - It is also useful to add the following lines inside of the <vendorConfig> context, but these are purely optional: <headsetWidebandUIControl>0</headsetWidebandUIControl> <handsetWidebandUIControl>0</handsetWidebandUIControl> <headsetWidebandEnable>0</headsetWidebandEnable> <handsetWidebandEnable>1</handsetWidebandEnable> From voip-info. /b On Feb 1, 2009, at 12:03 PM, peder@networkoblivion.com wrote:
I have an xml config file for the 79x1, but there is no mention of wideband and/or g722. I found a doc on CCO that says that the 7941 and 7961 support g722 for sccp and sip, so if you find some xml that mentions g722, I would appreciate seeing it as I have a couple of those phones. I know there is a "<preferredCodec></preferredCodec>" entry, so maybe you just add it there like on the 79x0 versions 'preferred_codec: "g729"'.

I found it finally. Now if I had the full XML I could pick apart for all the options that would help too.

Wow, can't even find the tech doc via my CCO login even. Gotta love Cisco and the support for SIP...
Probably have to find someone with CCM and look at a config that CCM made up, as that should have it if they enabled for the phone.
