Quoting Ed W <[EMAIL PROTECTED]>:
one thing I thought about, but never actually did was to install a damping circuit across the line - a phone plugged in the line never actually rang or if it did it was so short it was imperceptible. I figured just a load across the might damp down the test pulse enough to not be tricked into ringing the channel bank. social engineering rather than technical engineering eventually solved the problem though. > >> I'm fairly certain the problem is with the phone line.
