[asterisk-r2] OpenR2 Thailand problem

[Peter Lindquist]

Dear all,

Trying to get OpenR2 working in Thailand with TOT (Telephone 
Organization of Thailand). Unfortunately I have very little information 
from TOT, they basically just say it's a E1 CAS R2 they provide.

I have latest Trixbox set up together with libmfcr2 (OpenR2 version: 
0.1.1, revision: 64) and asterisk compiled from the svn source 
(1.4.21.2) from libopenr2.org.

My problems are the following:

1) When I make an incoming call - there is absolutely nothing happening, 
I see no ring indication or anything on the PBX. The call is eventually 
timed out by my telco.

2) When I make an outgoing call I see the following in the asterisk log:
[Oct 27 21:06:32] DEBUG[13425] chan_zap.c: no MFC/R2 category specified

3) When reloading chan_zap I see:

I could really use some help in how to troubleshoot this and get it working!
