[Asterisk-Users] X100P random hangups - Please help with suggestions

[Vassilis Konstantinou]

This one is driving me crazy. So any suggestions will be very welcome.

My setup:

Suse Linux 9.0 (Pentium 4, 1GB)
Asterisk: current stable (1.0.3?) - tried the head CVS before Christmas but 
did not fix it
2 X100P clones - one for a UK BT line, one connected to an ATA186 
configured for a UK BT Broabband-Voice service (MGCP)
1 ATA186 (SIP) connected to two dect internal phones (configured as 
extensions 5000-5001)

The problem:

Both of the X100Ps seem to randomly hang-up both incoming and outgoing 
calls. There is no fixed dureation but it always happens. Sometimes as soon 
as a call is answered and sometimes at any point up to 10-15 minutes. All 
calls through my true VOIP lines (I use sipcall in UK and fwd) are fine and 
never disconnect during the call. The X100Ps seem to detect the "real" 
hangup properly (of course).

Things I have tried:

1) The latest CVS (up to early December). No change
2) The current stable. No change
3) Playing with the rxgain in the zapata.conf file (no change)
4) Using the Loopstart instead of Kewlstart. No false hangups here BUT as 
expected lots of line noise. Is this a good clue to what is happening? Are 
there any parameters I can tweak to make the Kewlstart driver a bit more 
reliable?

Please help. This is driving me (and the people using the system crazy).
