asterisk users - Jun 2015 - Find out or log negotiated codec for SIP channel?

Hi, despite some searching I haven't found an answer to this question:

Is there a way I can see in the log, or find out in the dialplan, what
codec has been negotiated for a SIP channel? If possible, I'd like to
do this in both Asterisk 11 and in an old 1.2 system.

What I'm specifically trying to do is to determine historically the
usage of the G.729 licences installed in a system, but an answer to
the more general question would be useful.

Thanks
Tony

I believe  "core show channel <channel name>" or "sip show
channel <channel
name>" may help you.

negotiated when you enable the DEBUG logger channel.

You probably want to read through the logging documentation on the wiki.
