[asterisk-users] Record in mp3

Fri Apr 24 12:40:45 CDT 2009

I’m sure someone will correct this if I’m wrong – Asterisk can’t make direct
mp3 records because it’s not a supported codec.  Typically Asterisk records
anything as a gsm, ulaw or alaw file, depending on the codec used to run the
connection to the phone.

The recording I want is to save some reminders that my users can record. It
is not to save a conversation. So I think that there is not an overhead in
converting the audio on the fly in this case.But the question is: Asterisk
suport generate mp3 files directly?

you probably don't want to record directly to mp3 as there will be an
overhead in converting the audio on the fly and this will probably break
your call recordings... you should either record in the codec you are using
for phone calls (i think?) or in .wav and then convert afterwards (correct
me if i'm wrong someone!).

But have you tried to record directly in mp3, without to covert the file?

The way I read to do this is to use sox to create a wav file, then use lame
to convert the wav to mp3.  I did this for some MOH files.

Somebody knows if I can save files in mp3 with the Record command on
Asterisk?
I try to recompile sox to suport mp3 but Asterisk return the folowing
message when I use the Record command:

- Executing [*40 at liberado15:15] Record("SIP/1201-083453c8",
"/var/spool/asterisk/alarme/alarme-1201-200905121212:mp3") in new stack

I'am doing something wrong?

Thanks
