If I have VOIP (Voice over Internet Provider) phones or cable phones, will the security system be able to communicate properly with the monitoring center?
When the cable phone service or VOIP phones are connected correctly at the site, which is the demarcation block (typically where land line phones come into the site), then security systems will for the most part be able to receive dial tone to dial out in the event of an emergency. If the cable phone service is connected to the nearest phone jack next to the router provided by the cable company, your security system is vulnerable to dial tone loss or other unwanted issues with cable phones (see industry whitepaper).
