Cisco 801 configuration problem, please help

[EnglishGuy]

I have a cisco 801 isdn router, my configuration script is as below, it will not dial on demand, or if I force a line connection will not move traffic, so no pages can be found.
Would you be kind as to take a look and see what must be so obviously wrong!(maybe a line missing?)
I know my pc and ip addresses and masks are correct beacause when I plug my 761m router in it works fine.
My pc lan address is 172.16.1.1
Subnet mask 255.255.0.0
Default gateway 172.16.1.252
Randomly allocated ip address
I used the gui setup
