[Asterisk-Users] Playback Volume for Record Application

[Hadar Pedhazur]

Thanks Steve. Right after I sent my note, it occurred to me that I 
could create a dummy voicemail account, and point my current "Record" 
extension to that, and use Voicemail to record the "higher volume" 
version.

I just did one quick test, unscientific at best, and I think the above 
works reasonably well. Instead of leaving a message, I actually 
created a dummy vm user, and used VoicemailMain to record a "busy.wav" 
file, which I then moved to a normal "sound" file, and used the 
Playback application. It sounded enough louder to me than the original 
"Record" application made it.
