Hi, I'm trying to configure an E1/R2 provided by Telefonica in Colombia using a Digium TE220P. I've installed dahdi-linux-complete-2.1.0.4+2.1.0.2, openr2-1.1.0 y mfcr2 following the instructions given by Moy in his tutorial. I didn't get any error during installation and I tried to set some options in chan_dahdi.conf but I cannot obtain an E1 synchronization. First span is connected to provider equipment and a technician have been done a loopback test on it. I'll attach my configuration files if someone has a suggestion. Thanks in advance.<br>
