Alarm monitoring service like ucontrol that uses DSC native communication hardware?

[Heath Roberts <htroberts@xxxxxxxxx>]

My alarm (a DSC 4020) is monitored (and supposedly maintained) by the
company that installed it, and for several years I was happy with
their service, but for the past six months they're not responding to
troubles and not returning phone calls.

Ucontrol seems like it has a nice feature set, but I don't really like
the fact that it uses add-on hardware. Does anyone offer a similar
service compatible with DSC's IP interface (and dial for backup)?

On a related note, does anyone have suggestions for obtaining the
'installer' code for the alarm? It's not the default from the manual,
and I don't want to reset and re-program the alarm.

Thanks,
Heath
