How do I set up a system that allows my security system to call out wireless?

[Steven]

Hello friends,

I want to set up my security system to call out wireless to the monitoring center, at the moment it is calling out on land-line which I want to disconnect, I know I need a voip router connected to my security system, but how does the computer or modem receive the signal and how does it dial out?

Best regards
