asterisk users - Jul 2005 - Re: Asterisk-Users Digest, Vol 12, Issue 103

Interesting story. I was following up any wild goose chase i could to find
a resolution including cleaning dust out of the machine. At 4 pm I plugged
the line in and called for the sake of luck, and it was back to working.

In the mean time, thanks for the troubleshooting advice. I will keep this
in my log book so I have the steps for next time something goes awry.

We'll need at least some technical data to even guess at what's wrong.

Copy and paste output from
'ztcfg -vv'
'lsmod'
'dmesg' (looking for lines like Module 0: and TDM400P Rev H
entries from /etc/zaptel.conf (remove all the commented lines please)
entries from /etc/asterisk/zapata.conf (only those that pertain to [channels]
which o/s distro are you using
which asterisk (stable or head) and version
output from 'zap show channels'
output from 'zap show status'
CLI output for an inbound call where you here the noise

Give us a hint as to which zap channel you're calling in on.

Given your reported results, you seem to have the same problem that
a number of us TDM users have seen; the card goes out to lunch after
some variable length of time. Usually that's somewhere in the week
to two week area, and typically its been reported with rev E TDM
cards (look at the 'dmesg' to see what revision you have).

There has been several hardware changes made to the TDM card, and I
believe the latest is rev I. Since replacing my rev E card with a
rev I card, I've not seen a lockup. However, I'm typically messing
around with cvs-head and haven't left the system up for two weeks
for a long time.

If you have a rev E card, call digium support and tell them what's
happened and they should replace it since its a know problem. The
card has a three year warranty and has only been on the market for
about a year.
