[asterisk-users] UK BT ISDN30e PRI Problem

[Mike Hardman]

Ok Guys, I've done a tonne of hunting around on this problem, but
can't find much help.

I'm running:
asterisk 1.4.19.1
libpri 1.4.3
and zaptel 1.4.9.2 which I believe has been modified by RedFone to add
the ztd-ethmf module.

My interface is a RedFone foneBridge2 4 Span; and I'm connecting to a
BT E1 PRI / ISDN30e with 15 lines on span 1, and a legacy Panasonic
PBX on span 4. Upon connection of the E1 I get the following in pri
debug span 1:

Now I'm sure that this line is q931 and not 921, but I cant seem to
find where I configure this... My configs are as follows:

Zaptel.conf:

dynamic=ethmf,eth0/00:50:C2:65:D1:DC/0,31,1

I should note that I have tried this with and without crc4 on the
spans; both with identical results. Could anybody shed any light on
this or point me in the right direction? I'm now not sure what I'm
missing or where to go looking for it?

Thanks guys and gals.
