"Sip show channels" will give you the active codec. You can get the information using an AGI or a system command.

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? -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
