Yeah...  I see things went their usual downward spiral from here.  Some
professionals have pretty strong feelings about voice dialers and many
DIYer's have attempted to use the "page" option to dial a cell phone
with little to some success.

I consider my family to be my most precious "gift" and wouldn't consider
anything but a monitored alarm system to protect them.  Your self
dialling security system will do you a lot of good when the carbon
monoxide detector or smoke alarm goes off in the middle of the night and
you're fast asleep with your cell phone turned off or "on charge"
downstairs.  Or worse...  some creep decides to break in and winds up
confronting you in your bedroom.  A GSM module, a professionally
installed and monitored alarm system is a small price to pay when you
weigh it against the alternative "cheap solution".  This is just my
honest opinion (which is thankfully shared by many here).  One of the
regular posters here lost his son in a house fire.  And I was called in
to help repair a fire alarm system after a fire struck an apartment
building in the wee hours of the morning several years ago.  Two kids
lost their lives in that one and I'll never forget it.  I've kept these
individuals in mind every time I service, install, or inspect a fire or
burg system and won't compromise just to be the "cheaper choice".

I wish you well with your choice, but please do consider professional
monitoring as a security asset rather than the liability you seem to
think it is.
