BRI line used with Asterisk

[ktouati]

I am posting this thread with the hope that someone in UK (or elsewhere) had a similar issue:
We are using Asterisk as phone system.

Our issue is simple, we cannnot use our ISDN line, when watching asterisk console it gives a bunch of ISDN errors where the following is probably the most relevant:

Span: 4 TEI=0 MDL-ERROR (J): N(R) error in state 7(Multi-frame established)
 
We are using asterisk 1.8.12.0 with dahdi 2.6.0, on CentOS 6.2. I can post configuration and/or further information if needed.

Please do post your configurations as I will try to compare it with mine. I have the same problem, though I am currently out of UK.
