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

[Oscar Carriles]

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?

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

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?
