[Asterisk-Users] Re: Voicemail volume wav vs. wav49

[Aaron Daniel]

If the patch makes it past all the code checks and whatnot, and any kinks 
are worked out of it, it would make it into the next version of asterisk. 
Anyone that would want it in the older versions would have to backport it 
(I'll see about posting a patch somewhere that'll work for 1.2).  We just 
use the subversion branch of asterisk so I've applied the patch once to 
our voicemail server and do an "svn update" to pull down any modified 
files, and it just merges my changes in with the voicemail code for me.

As for the volgain setting, yeah, it's probably more related to the format 
itself than anything.  You'd have to get in and change the code of the 
format, however, if you do that, you universally change the volume.  If 
you notice, the wav49 files sound great on the phone, but not in email, so 
we took the route of fixing them through the voicemail program.  We've 
been using the patch since it's inception (and added a convert to mp3 
function also) and it's worked like a charm since.
