Strange dial tone after ADT installation
I am back with a question.
We have recently have an alarm system installed. Everything ey ok :), however, since then, our phones, although no problems with calls so far, now have strange dial tone. It starts with a few short beep beep, then the long regular one. Also, the indicator lights on the phones are blinking. Does this mean anything?
I just want to make sure that phones are not bugged or being monitored by some outsiders. Paranoia is starting to set now that I read more about cases where some alarm system companies' staff had been suspects in some cases of break-ins...ugh!
