[asterisk-r2] Incoming Calls hungup using MFCR2 Protocol

Fri Jan 20 08:10:05 CST 2012

Hi Diego

I have been working for a while in Barranquilla with both PSTN providers 
(telecom , Metrotel).
You should try the Argentina variant of MFCR2. (AR), it works fine for me.

Anyway, I believe you have a problem apart from the signalling variant. 
can you please post your system.conf (dahdi) configuration file and your 
chan_dahdi.conf

Regards,
