working with a compact ics 6.1
when the voice mail is disconnected the system answers and gives a modem tone

Could be the built-in ATA. Check its' settings.

Give a little more info please.
Do you mean disconnected as in Power off or unplug it??
Do you mean a caller hangs up ??
Do you mean if a caller calls in decides to hang up then another call comes in right away they get a modem tone ???
Only on one line? All lines??

What line is your alarm system on?

Oops...I meant the internal I-RAD, not ATA. That's what you're hearing.

I meant not connected in any way to the phone
system , no alarms or faxes on the lines either
you call in 3 or 4 rings later screeching tones .
what is an internal I-RAD and how do you kill it ? is that anything like a gremlin? I'am a panasonic dealer and only do these once in a while
