[asterisk-users] Voicemail Playback Issue

[Jim Duda]

Ever since upgrading from 1.2.X to 1.4.2, I'm having trouble with 
voicemail.  When played back, the messages start out okay, but after 10 
seconds or so, the playback speed starts to increase and the voice 
becomes illegible.  It seems like some kind of audio timing problem. 
Phone calls seem okay, in general.

I don't have any digium cards, but I am using ztdummy.  Ztdummy is 
loaded properly, and zttest gives be 99+% ratings.  "zap show status" in 
the asterisk console shows that ZTDUMMY is loaded into asterisk.

I've gone into the /var/spool/asterisk directory and played the WAV 
files directly, and I hear the same problem.  So, I'm guessing the 
problem is introduced when the voicemail is recorded.

Can anyone offer a suggestion as to what I can debug?

Thanks,

Jim
