i guess i'm just being naïve thinking that if i keep just picking-up-and-hanging-up on "unknown caller" calls, they'll eventually stop. if only the modem i bought supported caller-id, then i could just route the calls to oblivion. i could have sworn that i asked for anonymous call rejection when i signed up for caller id, which would be screening them out. i guess i should just fork out the $4.75 to get it activated now.
