[asterisk-users] Unicall + MFC/R2 line dropped immediately after connect

Hi,

I am trying to set up an E1 line with CAS signaling using available
unicall patches with libmfcr2 implementation. Inbound calls works well,
I am able to get DNIS and ANI from incoming call, but I am still not
able to make an outbound call with our local carrier.

After tweaking of protocolvariant parameter in unicall.conf I was able
to find proper values for inbound and outbound calls, but when outbound
connection is created, it is immediately dropped by opposite side
immediately after connection is made. I think, that we're receiving
billing pulses on the line and they're interpreted as a cleaning request.
I found similar problem in the list before:
http://lists.digium.com/pipermail/asterisk-users/2006-June/156732.html.
Steve suggested to use some kind of timeout to workaround this problem.
I've tried to change many timeouts in libmfcr2 library, without any
success. Can somebody help me to go around this line drop-down problem?

[asterisk-users] Unicall + MFC/R2 line dropped immediately afterconnect

Hi,

Clearback signal due to billing pulses normally drops calls after a fixed
amount of time 2 minutes or so, Can you stablish an outbound call and after
a while it drops? Or it never succeds?

[asterisk-users] Unicall + MFC/R2 line dropped immediately afterconnect

Please read the link from steve from softswitch

He report a problem at Brazilian setups regarding metering pulses.
Try:

mfcr2->clear_back_persistence_check = 300;
In your mfcr2.c

We have a similar patch that seems to work in Argentine variant
At www.eolix.com.ar/descargas/patches/mfcr2
