Anybody had an issue with PRI where users cannot dial out? Customer gets a busy signal when trying to call out. If they receive an incoming call, outbound starts working.

Happens every morning. Once they answer an incoming call, outbound starts working.

System is a 9100. Weird thing too is in f-route table for 911 dialling, we had to remove all digits and then reinserting 911 vs usually setting it as a two digit number. 9,911 worked right off the bat. Going to try setting 9 back to a trunk access code to see if maybe something goofy going on with f-route tables.

Spoke with a colleague who has experienced similar issue on 9300 that intermittently cannot call out. Telco of course says nothing wrong with the PRI.
