I use software to hang up on private/restricted calls and other calls from phone numbers that my caller id on my modem detects (using CallZap at softwareevolution.com). But, I still receive a large number of these calls and they still ring through on my phone for a single ring. That might not seem like much, but when you receive 20-40+ single ring calls, especially in the middle of the night, it can become just a bit much. Are there any modem commands, software programs, and/or telephone devices I can use to allow my modem to capture the caller id data and hang up on unwanted calls, without passing that first ring to my standard phones. Thank you so much for your help; it will really improve my quality of life.
