I've been a happy user of asterisk for over a year just for a small home
setup (a Digium TDM400P with one POTS line and three internal extensions
plus a couple of SIP phones). I recently moved from running Fedora Core
6 running * 1.4.1 compiled from source and zaptel 1.4.7 to Fedora 8,
using the RPM package for * 1.4.18 and zaptel 1.4.9 . It worked fine for
a week, but suddenly I can't dial out any more. Incoming calls work
fine, and outgoing calls through my Teliax line (IAX2) work fine, but I
get a fast busy if I try to dial out through the land line. All that
appears in the messages log is:
[Apr 2 07:13:48] WARNING[24249] chan_zap.c: Detected alarm on channel
4: No Alarm
[Apr 2 07:13:48] NOTICE[24242] chan_zap.c: Alarm cleared on channel 4
"core set debug 3" doesn't give any more detail.
I have tried stopping asterisk, restarting zaptel (unloading and
reloading), and starting asterisk, but the behavior persists.
Anybody know what this means? Has my hardware suddenly gone bad? Is
there some way to debug this?
I apologize in advance for not knowing all the telephone terminology; as
I said, this is just a small home setup.

Tacky as it is to answer myself, I also wanted to mention that I also
tried shutting down, powering off for 30 seconds, and rebooting, and
that doesn't fix the problem either. Also, dialing out on the POTS line
using a directly-connected phone (bypassing the * server) works fine.

Hi Greg,
If you have subversion installed on your server, could you try using
this version of zaptel:
http://svn.digium.com/svn/zaptel/branches/1.4 at 4122
There have been some relatively recent changes with how certain signals
are handled in zaptel and reported by asterisk.
Cheers,
Shaun |

What's the svn command to fetch it and I'll try it.

Not a problem here, as the monitor is on the other side of the room from
the server and the wire from the wall plate to the server doesn't go
anywhere near it.

I think the card is OK; all the extensions plugged into the FXS ports
work fine and incoming calls also work. This looks more like a driver
problem. And I've had trouble with the zaptel drivers before. I had a
situation where my machine would just stop (no crash, just totally hung
and unresponsive). A zaptel driver upgrade fixed that.

It's a bit early for that here; we won't see our first thunderstorm for
another few weeks yet.

That's what I intend to try tonight. I hope I don't have to rebuild
asterisk from source too, as having the fixes applied to the RPM (such
as the one for the recent security problem) was one of my main reasons
for upgrading the system, so I wouldn't HAVE to maintain asterisk from
source any more.
But I did have to get the zaptel driver from ATrpms, as it isn't part of
Fedora 8 (maybe it's got some license or patent restrictions on it so
they don't distribute it for the same reasons they won't distribute MP3
decoders?) If the update does fix my problem, I will let the ATrpms
people know about it.

Thank you to everyone who offered assistance. For now, upgrading the
driver has fixed the problem: outbound calls work again. It does leave
open the mystery of why it worked fine for a week and suddenly quit, so
I can't be 100% certain that everything is really fixed until it has
been stable for a while.
