I am at a cutomers site with an ongoing issue with RCN


SL1100 with PRI (Partial ) 7.21

cant make any calls out on PRI Trunks

incoming seems to work fine


RCN in process of setting up vender meet just wondering if it could have anything to do with system

I dont believe it was installed be an NEC Dealer



using Adtran rebooted all devices so far RCN dosent seem to have good diagnostic from far end


I can grab the channel and then the call drops and I get a slow busy signal



any thoughts
