asterisk users - Mar 2005 - X100P voicemail volume too low (quiet)

Hello,

I'm running Asterisk 1.0.6 with zaptel 1.0.6 on Gentoo
Linux with a 2.6.11-gentoo-r2 SMP kernel (but no SMP
hardware) and mpg123 0.59s-r9.

When I leave a voicemail message via my X100P, the
message is way too quiet. I can barely hear it.

I googled this a bit, and I saw similar complaints with
older versions, but no resolutions. Also, many complained
that it was only too quiet via email, but checking the
message via SIP was OK. This isn't the case for me. It's
just too quiet all around.

However, if I LEAVE a message via SIP, it sounds fine.

Does anyone have any hints, tips, tricks, solutions?

Thanks!

It's a known issue with x100p and TDM-fxo cards, See bug #2023 
and add your comments/experience to it.

On my TDM400 FXO cards, leaving and checking voice mail via the legacy PBX
(very short loop length, in other words) is fine.  On the POTS line I use as
a voice mail back door, I had to boost the RX gain a lot (10 dB!) to get the
voice mails and other recordings to end up the same volume as the
pre-recorded prompts.  (On the PBX lines I'm also cutting the TX gain by 6
dB, because it was deafening compared to outside phone calls otherwise.
It's possible our Toshiba PBX just has very poor gain balance.)

In either case, voice mails sent as email attachments are *very* quiet.  I
wonder if anyone has tried hacking in a script to normalize them before
sending them?

For what it's worth I have had this issue with voicemail in stable against
T100P PRI interfaces for a long time. It affects the files when played back via
a handset or via email/headphones. I had to switch the on-disk recording
protocol to 'wav' from 'wav49' to get a consistent audio level
on all recordings. 'gsm' produced the same behaviour as 'wav49'.
