A friend's condo was broken into despite the presence of such a security
system; the detective who investigated theorized that the burglars simply
called her number and let it ring, thus tying up the line so the alarm
couldn't dial out.  Anyone know how these alarms deal with that possibility?
Do some alarm companies recommend a dedicated, unlisted phone line (hers
didn't)?  If you had such a line, would it be all that difficult for a burglar
to patch a phone into it (externally - like at the junction box) and dial
(say) the time/temperature number to tie up the line anyway?
