[Asterisk-Dev] fast-forward & rewind

[Mike Reiling]

BTW, this doesn't go back/forward by 5 seconds, but you can change 
that.  Look at file.c.  I added the ast_waitstream_fr function.  You 
can change the time in that function.  I will soon be adding that to 
voicemail.conf, so you can change it easier.

It might look like I'm doing nothing, but at the cellular level I'm 
really quite busy.
