[asterisk-users] PRI Problems

[Klaus Darilion]

Hi!

Today I had problems with an E1 link to a Siemens PBX (Sangoma 2xE1 
card). Although everything looked fine (wanrouter status "connected", 
pri show status was also fine) there were no messages from the PBX to 
Asterisk.

The log file is below. I reloaded asterisk and the kernel module several 
times - disconnect and reconnected the cables but nothing worked. 
Finally I rebootet the server and than everything was fine again.

Does someone knows the reason for this problem?

thanks
klaus
