[asterisk-r2] Incoming Calls hungup using MFCR2 Protocol

Mon Jan 23 19:27:54 CST 2012

Juan
How about to swap E1 cable? I just mean to change cable connection, Telco provider on port 1 should be at port to and so on with port 2 and check  error message (channel (32) etc).
By the other way, I guest   A102 port 2 configuration should be span=2,2,0,cas,hdb3.
By the way when dahdi configuration have changed please stop and restart services.

Best regards

Hi Diego

As I told you , I believe your problem is not related to the mfcr2 variant.
This seems more like a timing, phisical or drivers problem to me.

You use Sangoma and Wanpipe , and I have not experience in those.

Can anyone check if this might be related to a hardware / drivers issue?

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
