Cisco 803 DDR

I have been configuring 2 Cisco 803's (IOS 12.0) routers to dial each other over ISDN.

I seem to be having difficulty with the initial call set up within PPP as I continue

to get LCP Timeouts after it enters an LCP listen state.

I get LCP messages at the

dialling end but no LCP/PPP at the remote end. All that appears is the ISDN call

set up at Layer 1 and 2

In my initial configuration I set up both routers at 64k but on advice from Cisco

Troubleshooting Assistant on the TAC site I change the speed to 56k.

However at that stage the "central" router would not dial out at 56k. The call

continued to set up at 64k whilst a call from "remote" was intiated at 56k.

Any ideas???

Re: Cisco 803 DDR

You have to update the IOS to a higher version than 12.0(5).

I got the same problem and updated to IOS 12.2. Now the DDR works fine.
