Thx for help. Actually I read document many times and tested a lot but not useful to me.
I have two 1841 routers and would like to connect them directly via GSM not through GPRS.
I have configured my ROUTER1 as Dial on Demand as you may see its config in attachment. Its ok and dials out without any problem.
I have problem in my second router config (ROUTER2) . I have attached its config too.
As you can see in attachment file, modem parameters ar ok and S0=1 which means its in auto answer mode.
When I dial from Router1 to Router2 , Router2 dosent reply and so dial fails. But when in Router2 I connect to modem (with telnet 220.127.116.11 2018) and again dial from Router1 to Router2 , it hanhup and both modems connect to each other.
I just would like to know what is my foul in ROUTER2 configuration and if you have any suggestion for it.
