[asterisk-users] Zaptel Problem - Unable to create channel of type 'Zap'

Wed Jul 19 12:54:03 MST 2006

Im not a PRI guru, just configured once one of our asterisk servers in
loop using PRI for testing purposes (we were getting problems with
MFCR2). But for my experience i can tell you that OK in zttool (no
alarms) does not means that everything should work. Only the physical
link is ok, but the call protocol may be having problems. I know you
have a card with only one port, but a very good test would be make a
crossover cable and make a loop in your box, configuring 2 spans, one
of them as pri_cpe and the other as pri_net to see if you can make
calls that way.

Regards
