Disable 801 router to initiate an ISDN connection

We’re using a Cisco 2600 series router to give our cutomers remote support over ISDN.

Untill now our customers use Cisco 761M routers.

The connection is initiated from our 2600 router, and the customer calls us back. When the connection is disconnected a customer cannot connect to our office, because we use the “set auto off” command on the 761M router.

The 761M router is “end of life” and therefore we must use the 801 router for our remote support solution. Everything works with the 801, but the connection can also be initiated from a customer.

Our question: Can we configurate the 801 router on such a way that the connection can only be initiated from our office (like the 761 “set auto off” comamnd)?

Use an access list to stop any interanl networks or node initiating the call.
