Re: [asterisk-users] Determine negotiated codec in script
So I did a little more digging and found a real simple answer:
${CHANNEL(audionativeformat)}
tells me 'ulaw' or 'siren14' and lets me pick the right file extension
for the record function.

Sorry if this is an obvious question and perhaps my Google foo isn't
right on this one:
I have calls coming into an Asterisk server that may be using 2
different codecs. I am recording audio in both cases but the
challenge is knowing which codec was negotiated at call setup. I need
to pass the proper format to the record command as the codecs cannot
be transcoded and are only supported for playback/record/passthru etc.
Is there some global variable present that I can look at for codec
identification?

Re: [asterisk-users] Determine negotiated codec in script
Sip show channels will give you the active codec. You can get the information using an AGI or a system command. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Tom Browning Sent: Tuesday, September 13, 2011 4:19 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Determine negotiated codec in script Sorry if this is an obvious question and perhaps my Google foo isn't right on this one: I have calls coming into an Asterisk server that may be using 2 different codecs.
