I just talked (through the on-line text
chat) with a sales rep this morning about
this. He stated that the system goes through
the phone numbers until someone presses the
0 to listen in. I assumed he meant it would
only dial each number once. In my experience
testing this unit, this is NOT the case. In
fact, the system has hung up on me before I
could answer my phone and never called
another number. It is supposed to repeat the
message 3 times before it hangs up. I'm
going to test it again tonight.
