[Asterisk-bsd] TDM400P - odd issues

[Roy Hooper]

Hi,

I'm running a TDM400P with 2xFXS and 1xFXO on an AMD64 dual-core  
machine (Nvidia chipset motherboard) running in i386 mode on FreeBSD  
6.2.  I had been experiencing intermittent problems with the TDM400  
setup.  The old problem I used to see was that channel 2 (2nd FXS)  
would have battery but no dialtone, and channel 4 (FXO) would be able  
to place outbound calls, but would miss incoming rings/callerid and  
not pickup.  Channel 1 (FXS) would work just fine.  This used to  
happen every few weeks.  Recently, it was happening every few days,  
before the new problem cropped up...

Today, my wife reported an even weirder problem:  any attempts to use  
the FXO would result in really loud static/noise after the FXS was  
joined to the FXO, and a the outbound dialing did not occur.  I  
checked, and the analog line works perfectly.

Here's what I've tried:
- I tried a power cycle.  Same problem.
- I upgraded the zaptel driver to the latest port (1.4.6) and  
asterisk.  Same problem.
- I upgraded asterisk.  Same problem.

Unfortunately, I can't recall what previous port versions I had  
installed, but they weren't very old, and the first problem persisted  
through several versions of the ports for both asterisk and the  
zaptel driver.

I now have:

# Installed ports
asterisk-1.4.9_1    An Open Source PBX and telephony toolkit
zaptel-1.4.6_2      A FreeBSD Driver for FXO, FXS, BRI and PRI  
Telephony Cards
asterisk-addons-1.4.2 GPL modules for the Asterisk Open Source PBX

# uname -imrs
FreeBSD 6.2-RELEASE-p6 i386 GENERIC

# zfcfg
Keyword: [fxoks], Value: [1-2]
Keyword: [fxsks], Value: [4]
Keyword: [loadzone], Value: [us]
Keyword: [defaultzone], Value: [us]


Additionally, I have the following /usr/local/etc/asterisk/ 
zapata.conf for the FXO:

context=incoming
rxgain=1.0
txgain=1.0
signalling=fxs_ks
ringtimeout=8000
immediate=no
callprogress=yes
busydetect=yes
busycount=6
echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
channel => 4

I also tried:

context=incoming
rxgain=1.0
txgain=1.0
signalling=fxs_ks
ringtimeout=8000
immediate=no
echocancel=yes
channel => 4

and the static/noise was even louder.

Here's my zttest output:

Left to test:
- upgrade to latest 6.2 RELENG version.
- non-SMP kernel.
- Linux :-(

I'm beginning to suspect bad hardware.
