Re: srst problem, can not call from PRI line

For incoming calls you'll need to add dialplan-pattern under call-manager-fallback to expand your DNs to whatever the telco is sending. For outbound calls you only have one dial-peer that will forward the last 7 digits, so only local calls will work.

Check to see if the PRI falls back to SRST when WAN is down, also posts results of "debug isdn q931" while making a call.
