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