[Asterisk-Users] voicemail volume with sipura 3000

[snacktime]

I have my sipura SPA-3000 setup so that incoming calls on the FXO ring
for 20 seconds then using dialplan 2 it dials my * server and drops
the person into voicemail.

The problem is that voicemail messages are way too quiet.  You can't
hear enough to understand what is being said.   If someone answers the
phone before the 20 seconds the volume is fine.  If I dial from the
sipura line 1 into voicemail and leave a message the volume it just
fine also.

I know most likely this isn't an * issue, but I thought maybe someone
else has encountered this problem?
