[Ben Thompson]

Package: libpri1.0
Version: 1.4.2-1
Severity: minor


Hi

I recently updated my Asterisk server from etch to lenny and I have started to recive
the following message when I recieve calls on my pri isdn link :-

[Mar 12 14:04:18] WARNING[4294]: chan_zap.c:8851 zt_pri_error: 1 copying 5 bytes LLC

I am not sure how much of a problem this is as I don't fully understand the message.
My Asterisk box is connected to a Siemens Realitis DX and here are the relevent configs as
well as some Asterisk debug :-
