Routing lost after a few seconds...

Hello everybody.

The setup is the following :

2811 router with ISDN-BRI interfaces and a WIC-1T.

The WIC-1T intf connects via an RS-232 cable to an external Motorola modem.

When remote users dial-in establishing an ISDN connection everything is fine.

When calls come through analog modem connections, call gets established, and PPP negotiation completes successfully.

At that instant and for a few seconds, the (analog) user has network connectivity (at this point tried by continuous pings).

"Suddenly" replies stop!

Only after disconnecting the call and re-connecting (temporary) routing is reestablished, to get lost again in a while !!

We have tried with-and-without Group-Async (config directly to the Serial intf) but nothing changed.

Any ideas, anyone ?

The current config - for anyone interested and after many try-outs - is attached...

Thanx in advance.
