Every attempt to play a file in Asterisk (that doesn't specify the 
extension) will use the 'best' format it can find for the call's format. 
The applications that ship with Asterisk do not specify any particular 
format, so your best bet is to provide the files in all the formats you 
expect your callers to be using, so Asterisk never has to transcode a 
file playback. The same thing is true for voicemail recording; you 
should record in every format your users might call in with, unless the 
extra disk space consumption would be an issue.
