[Asterisk-Users] E1 Connection breaks

[ePyron Felix Deierlein]

Hello,
 
we have a connection to a leagacy pbx (Siemens Hicom 150E) via PRI (E1).
Everything works really fine, but the connection breaks sometimes (there is
not really a time scheme), so that you could not dial from the hicom to * or
from * to hicom.
 
The only one to get the connection back is to reboot *.
 
Today is our first production day, so it is rellay bad.
 
 
The connection to the PSTN (E1 to DTAG) works without any problems.
 
* runs at a SuSE 9.0 with 2x PIII 1000MHz and 512 MB RAM.
Hardware:
1 WCT405p
1 AVM C4 (with chan_capi)
 
* Version: CVS-05/29/04-17:36:55 stable

I have created a logfile (via putty) with pri intense debug. I have attached
it zipped. I hope that is okay? -> It seems not: so I have uploadet it to:

I would be very happy with any help you could provide.

Thanks
