Disabled the advertise 722 enterprise parameter but still seeing phones advertise it

[Jay Schulze]

Hello

I disabled the enterprise parameter 'Adverstise G.722 Codec' however I continue to see it advertised from CSF phones. CUCM version is 11.5.1.12900-21.

Here is an example. It's just a straight outbound call from a CSF phone to ACME. It also sending out all kinds of dtmf types as well which the provider doesn't like.

Jabber or CSF devices are not using the g722 that you disabled.

It is g722.1  you can see the different in the SDP message.

Here is the codec in a SDP I responded to yesterday.
a=rtpmap:9 G722/8000

Here is the codec from the CSF profile.
a=rtpmap:104 G7221/16000

So to continue you should be able to limit out this via regions or the audio codec preference list if you wanted, or by filtering it through a cube router and setting the voice class on the router.

You can change the DTMF relay on the router as well if you wanted, I also don't understand why your carrier would have a problem with your csf device advertising to any dtmf-relay methods this would seem like a good thing if you asked me. That way it can select from the list what it supports.
