[asterisk-users] Asterisk + Unicall + Telmex E1 MFC/R2 Argentina + Meridian

[Facundo Ameal]

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:

Thanks in advance!
