[asterisk-users] Re: Choice of soundfile format

[Steven]

By the OP reference to wav or gsm, I assume he is talking about the VM recordings.

Sorry, I do not have the answer though.

The one that is encoded in the same codec as the codec of the channel.
On zap it's often alaw or ulaw so you can encode your files like that.
You can encode the same file with different codecs and save it with
different extensions (matching the codec) and asterisk will pick the
most suitable one.
If the channel is gsm, a gsm encoded file would be most efficient, as it
doesn't need transcoding at all.
