asterisk users - Dec 2006 - Voicemail hangup by gateway?

Hi,

I have a spiffy new gateway which seems quite promising.

It's the Audiocodes MP114 FXS_FXO (2 of each).

I have got it configured and working reasonably well, but have a couple 
of issues.

1) Asterisk 1.2.13 voicemail seems to be hung up on by the gateway 
after 10 seconds.  This isn't asterisk saying it's quiet for 10 
seconds, it's the gateway deciding it's time to go by by.

2) I am still working on tuning the volume parameters to get minimum 
echo and maximum audio.

This gateway is much more stable and workable then either of the other 
options I have struggled with.  It works the way it should, and 
continues to do so (novel).

Thanks for any ideas/experiences/help with the above.
Marty

PS Yes I have a call in to the vendor also,  but hope someone here has 
ideas too.

Ok,  I am still annoyed by this,  I did an SIP debug and I can see that 
10 seconds (after the beep) the gateways sends and SIP "bye" to 
Asterisk.

I have exhaustively searched the Gateway's web interface looking for 
something that might be causing this, but can't find anything (enabled 
that is).

Has anyone out there seen this with audiocodes hardware before? I 
assume it's due to the fact that when the voicemail system starts 
recording, there is no longer any audio going toward the gateway that 
it decides the call must be over.

Hoping for some help.
