asterisk users - May 2008 - show CODEC in CDR

Hi,

In asterisk is there a way of saving the voice codec used in the call in the
CDR.
I am having mostly SIP calls, with few H323 calls.

I have been trying for the past 2 weeks to figure it out on my own, but with no
luck.
There are no channel variables that can give the current codec used in the call,
or used in the channel.
I need it because I must charge the clients according to the codec for
the?individual calls.

I even tried looking in the AGI commands for asterisk, and many external AGI
packages, but with no luck.

Can this be done?

Your help is much appreciated.
Thank you and best regards,

Antoine Megalla.

What happens if you put something like this in a macro

Verbose(1,${CHANNEL(audioreadformat)});
Verbose(1,${CHANNEL(audiowriteformat)});
Verbose(1,${CHANNEL(audionativeformat)});

and call the macro from Dial()

Dial(...,,M(my-codec-log-macro));


Gr??e,
