ISDN Dial on Demand with Callback

[Alistair-Roberts]

Hi,

We run an ISDN network with Dial on Demand, using the callback funtion to start up links.

We have an intermittent problem where the callback function fails. E.g someone in a remote site starts a Metaframe app (one of our kickoffs) but it fails to connect. It appears the the remote doesn't start the call.

Our remote site are using 1600 series routers connecting to a 3640. Any one have any suggestions.

The 1600 routers are currently running IOS 12.0(3)T is the a preferred one of Dial on Demand etc?

12.0(3)T should be fine for DDR.
