asterisk users - Jan 2007 - Asterisk + Unicall + Telmex E1 MFC/R2 Argentina + Meridian

Hi everyone!
I'm having some issue trying to place calls with asterisk connected to
an E1 R2 from Telmex Argentina. The other E1 port is connected to a
Meridian which also uses R2 protocol. Calls sometimes fail with
different error messages such as: Unicall protocol error 32773, 32772,
32769. Some other calls fail saying:
                           Far end disconnected(cause=Destination out
of order [27])
                           Far end disconnected(cause=User alerting,
no answer [19])
                           Far end disconnected(cause=Switching
equipment congestion [42])
                           Far end disconnected(cause=User busy [17])

I don't think those causes are real, because if you use another line,
yo establish the call. Could it be something about timing of ABCD
bits?

I'm using:
Asterisk 1.2.6
Zaptel 1.2.5
libmfcr2 0.0.3
libunicall 0.0.3
libsupertone 0.0.2
spandsp-0.0.3

And this is my unicall.conf:

[channels]
loglevel=1023
usecallerid=yes
hidecallerid=no
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callerid=asreceived
callreturn=yes
echocancel=no
echocancelwhenbridged=no
echotraining=no
rxgain=0.0
txgain=0.0
callgroup=1
pickupgroup=1
immediate=no

musiconhold=default
protocolclass=mfcr2
protocolvariant=ar,10,4,15
protocolend=cpe
group=1
context=from-zaptel
channel => 1-15
channel => 17-29

loglevel=0
usecallerid=yes
hidecallerid=no
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
callerid=asreceived
callreturn=yes
echocancel=yes
echocancelwhenbridged=yes
echotraining=yes
rxgain=0.0
txgain=0.0
callgroup=1
pickupgroup=1
immediate=no

protocolclass=mfcr2
protocolvariant=ar,0,12,12
protocolend=cpe
group=2
context=hacia-afuera
channel => 32-46
channel => 48-60


Thanks in advance!

Greets!

Share your knowledge, use free software.

Sometimes timers need to be adjusted on the mfcr2 source code.
Sometimes is missconfiguration. Anyway, may be this document can help
you out to debug the problem:
