[Asterisk-Users] Configure E1 PRI

[Marcelo Rodriguez]

After sometime I got my E1 PRI configured correctly in /etc/zaptel.conf
and I now don't see any alarms on the E1, but I can't still dialout
correctly, I enable every debug that I could though of and this is what
I see:
At the end the D-channel is down and I cannot even try to connect
another call because it tell me that the zap channel is unavailable ,the
other this that I notice is that I got a message saying that there are
no more D-channels available, please HELP!!!
