[asterisk-users] cli command show codecs

Thu Sep 1 09:26:53 CDT 2011

Thanks again @Danny.

File converter worked like a charm.
asterisk -rx "file convert /var/lib/asterisk/mohmp3/wav_Track11.wav
wav_Track11.alaw"

I coped the new file from sounds/ folder to my desktop
And I tried to upload the new .alaw file using FreePBX,

I got the following error:

Error Processing: "sox failed to convert file and original could not
be copied as a fall back" for wav_Track111.alaw!
This is not a fatal error, your Music on Hold may still work.

Pls help with this last bit.

Thx
Sans
