initiate router connection in one direction

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

Our customers are using Cisco 801 ISDN routers.

When we connect to a remote site, the 801 router calls us back.

But our customers can also build up a connection to our network, also when we’re not giving support.

Is it possible to prevent that the 801 router makes a connection to our site when we’re not giving support? Is it possible that only we can initiate up a (dial-back) connection?

Re: initiate router connection in one direction

first, you should have posted your question in the WAN Routing & Switching forum.

do you also manage the 800 ?

If so, you can try to remove the dial-string or the dialer map and just configure a call back string.
