Make sure that logging is not disabled

on the serial interface. Otherwise, if

you are using anything besides the

"backup interface" command to provide

backup (ie dialer watch, floating static

routes, etc) then it could be that

dialing occurred due to your config. You

can enable "debug dialer" to see what

traffic caused dialing to occur.
