Maybe this will be better than my first answer – Audio files do indeed have codec formats. If you are in a particular codec (say G729), Playback/Background and MOH will search for files that match the codec format first, then transcode WAV/GSM/whatever you have to that format if it isn’t found. Ideally, you want to have a copy of each codec you can play for all sounds and MOH. Each of the “canned sounds” comes in each codec format (you pick the ones you want when you do make menuselect).

I simply convert all my audios (MOH, accouncements) to .wav format, 16bit, 11kHz (I believe this is the best format for asterisk). I am new to this and may be incorrect. Going forward, (a) How can I check the codec format of my announcements, MOH ? (b) How can I record/convert announcements, MoH etc to a particular format ? I believe its a good idea to prevent transcoding and save CPU overheads.

If your IVR announcement is not recorded in g729 and you see g729 on the channel when you call into IVR then it's transcoding as well.

However it does not track transcoding. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of RSCL Mumbai Sent: Wednesday, August 31, 2011 2:45 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] cli command show codecs asterisk -rx "core show channels verbose" does not provide transcoding details.
