Free voicemail greetings
Telezapper
This is a replacement for the $50 Telezapper. Working very similarly to the Privacy Box above, it plays one of the special information tones (SIT) - that is the bee-bee-BEEP tones you hear before a US not-in-service recording. The telemarketing dialer hears the tone, assumes the line is out of service, and your number gets taken off their list.
GOOD JOB OK out of service
