[asterisk-users] No audio playing back voicemail from odbc

[Support]

Well, it gets even stranger....

I've installed version 10.2.1, instead of 10.7.1, and copied the configuration 
files from another identical server that is running 10.2.1 is working 
correctly.

I STILL can't get voicemail to play back.  I can hear the password prompts

Theses are, what I think to be, the relevant settings in voicemail.conf:

;minmessage=3
maxsilence=10
silencethreshold=128

When I set silencethresholdo either 500 or 64, I still didn't hear anything.  
(But I did hear several seconds of actual silence.  The .wav file contains 
nothing but silence.

So, fiddling with the silencethreshold in both directions, doesn't seem to 
change the symptoms.

Where else should I look?

TIA

Mike.
