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?
