[asterisk-r2] Incoming Calls DROPED with only 1 DNIS digit.

Wed May 26 12:18:35 CDT 2010

Thanks Moy,

And just for the records, I couldn't find any wrong configuration, or
something else. I spend all day trying to figure it out, but didn't
get the solution. Problem is, this server was in production, and they
were out of service for all day.

An the end, what I did was rolled back the asterisk 1.2 branch with
Unicall, and without any special configuration, it started working
just fine. I felt frustrated for this situation.

This in short, is what I did:

Original server Centos 4 with asterisk 1.2 and Unicall plugged to 1
Telco and Ericsson PBX.

Replaced with Elastix distro, then trying with openr2 1.2.0 and
asterisk 1.4 packaged with Elastix... and not working on incoming
calls.
Then, upgrade to openr2 1.3.0 and compiled everything else (asterisk
1.4.28 with openr2 patch)... at the end same behavior.
I tried even with timeouts, using the r2proto.conf... but same result.

At the end, I compiled every library required to get unicall working
with asterisk 1.2, replace dahdi with zaptel.. And it suddenly started
to work just fine, incoming and outgoing calls working right, this is
just a few lines of the chan_unicall receiving DNIS digits:
