I have looked at the config that you posted and I believe that the problem is that there is not a dialer-group for the async interface to identify interesting traffic. With no interesting traffic the idle timer will run out and terminate the call. I suggest that you add dialer-group 1 under the async interface. Try it and let us know if it helps.




thanks for your help.

my english is realy terrible.. :-)

pleas show my new config.

Than i have a connection txt where you can see that i can connect.

but i belive that (so i have see it by connect with ISDN) the call from my Client PC get no route to my network here. (peer)

I call the router with a 9,6 Kb Modem (Mobilephone) but i think that is not the problem. It have to worke!

Now i am 12 h here and i will crazy!! :-)

Thanks for Help
