I use a combination of AHP triggering a Dummy module that x10 Dispatcher is watching which "dispatches" batch file that pops off an instance of AlertDialer and ring goes my cell phone.
The batch file is nothing more than:
cd\program files\alerdialer
Alertdialer <phone number> "Text to say to you when it calls you"
To tell me that my security device DS10A has detected that I left my garage door open again.
Klugy, but wonderfully reliable and freeware (donationware)
