asterisk users - Feb 2004 - calls dropped with grandstream

I'm using a grandstream phone with asterisk.

Everything seems to be working fine, but every once in a while talking to
someone, the call is dropped.

A loud busy signal immediately interrupts the call for the grandstream user,
while the other person (connected through an X100P) is just cut off.

Does anyone know if there is a way to fix this?

Eventually I will replace the Grandstream, but for now I would just like to
fix this problem.

Have you tried using a soft-phone just to see if it's the phone or
something with your * system?  

Also, have you tried doing a asterisk -vvvvvvvvvgcr to see what exactly
is happening at this disconnect?

What is also help full is to send all the logger.conf output to a single
messages file
messages => notice,warning,error,debug,verbose

What firmware do you have on your GS?

Sean,

I had exactly the same problem and also blamed the GS. It turned out to 
be a hairline crack in the T1 cable connecting my channel bank to the 
Digium T1 card. I repaired the cable and the mysterious disconnects went 
away. It may be way off base for your case, but it might be worth some 
investigating.

I have firmware 1.0.3.81

I have a Cisco ata186, and that seems to work fine.  Infact, I've had that
up for about 3 months without rebooting, and it is still working great.

The dropped call problem only happens on the grandstreams.
