ISDN Dial on Demand with Callback

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.

12.0(3)T should be fine for DDR.
