Telemarketing (Junk) Call Blocker Reviews

Is it possible to keep the phone from ringing altogether unless the caller passes the black list? Does a two-port modem make a difference?

Great program to reduce junk calls. Flexible and robust. Supports several modems. I easily modified it with one change for my US Robotics 5686E. Blacklisted callers now ring once and are gone.

Nifty little program. I quite like it since it dealt with some telephony riff-raff pronto. I had problem using the US Robotics USR5637 (59bucks): inconsistent caller ID reporting - ID comes in after the second, sometimes third, sometimes fourth ring, at times not at all. TRENDNet TFM561U (35bucks) works consistently.
