asterisk users - Jan 2005 - Bristuff ZapHFC and Loosing D-Channel

Using the latest(?) bristuff (Asterisk 1.0.4-BRIstuffed-0.2.0-RC3a) I 
have problems with loosing the D-channel. Most of the time, after the 
message

"PRI D-channel down"

it only takes a second or so to come back up, noted by the message

"PRI D-channel up"

However, today most of the time the D-channel stays down. Calls come in, 
but can't be answered.

Does anyone know of a fix for this, or might have some insights on how 
to circumvent this problem?

Any and all help is greatly appreciated.

Hi!

Did you ever find the answer to your question?

I am getting the same message on the console every second:

   == Primary D-Channel on span 1 down
   == Primary D-Channel on span 1 up
   == Primary D-Channel on span 1 down
   == Primary D-Channel on span 1 up
   == Primary D-Channel on span 1 down
   == Primary D-Channel on span 1 up
etc. etc. etc.

I'm running Asterisk 1.0.5-BRIstuffed-0.2.0-RC5

The error is only visible however if I run * with -vvvvv
(but I guess I shouldn't see these messages nonetheless)?

The busydetect=no did the trick here.

Remco, are you running * on a SMP system ?
I cant get the bristuffed thing stable on my P4 HT.
I am now running it with i4l and HT disabled, but since it also hosts our
internal communication application coded in php with postgres as backend it
would be nice to be able to run a second thread when the database is busy.

Hi

This is normal behaviour if you are running isdn in PTMP mode, at least in
sweden. It is bothering with these messages, but I'we been running my test
site with two PTMP lines for months and everything worked fine.
It is said that some operators keep trying to turn off the D-channel in
PTMP-mode. But asteriskt keeps trying to turn it on.

This is usually no problem.

If you can't recceive calls, my exeprience is that there is some problem
with the msn that is set on the line.
