[Asterisk-Users] PRI configuration problem

[Andrew Aken]

We've been working for the past 2 weeks to get a new V400P working with 
our PRIs from the telephone company. We're trying to get the Asterisk 
server setup as a VoIP gateway for SIP and AIX. We can make SIP-SIP 
calls, but all calls from or to the PRI fail. This is the applicable 
entries from the Asterisk log (configuration files follow) for a call 
coming from the PSTN on the PRI. I believe that the cause of the error 
is related to the line, "Ring requested on unconfigured channel 0/23 
span 1". But as far as I can tell, the channels are all configured.
