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).
