Hello People and thanks for taking a look at my post. I installed a 2651 with a channelized T1 PRI controller, configured as 23 ISDN channels. The remote 804s dial the PRI just fine and everyone was happy until the first phone bill arrived. It seems that the phone company gave the customer a decent flat rate plan for the remote ISDNs initiating calls to the Host PRI, but not for the PRI to dial out to the remote ISDNs. sh isdn history shows the Host network contacting the remotes for unknown reasons for extended periods, therefore racking up the bill. I don't care about the traffic trying to call the remotes, it's not necessary. Only the remotes need to dial the PRI. How can I disable the T1 PRI from initiating calls out? The system is live, I'm not very experienced with the set-up and I can't afford to guess and experiment. Is it as simple as: dialer-list 1 protocol ip deny? Or will that deny the inbounds as well?
