I wanna setup a router(2811) with a modem to remote dialin.
since the modem did not have dial tone at first, so I find the AT command set and enter ats0=2&w0 in the modem, and later, it worked. I can dailin this modem with tone.
but after I connected the router(AUX)--modem--phone line and dialin again, the modem dont have any respond tone again.
I really confuese about this problem and dont know how to troublshooting the problem..
