VoIP & U-Verse

The truth about
VOIP (Voice Over Internet Protocol) & U-Verse

What is VoIP?

VoIP, Voice Over Internet Protocol is a new internet or cable phone service option available to anyone with a high-speed modem. VoIP allows phone calls to be made over an internet connection instead of through the traditional phone lines Plain Old Telephone Service (POTS). VoIP offers unlimited local, regional and long-distance calling within the US and Canada along with popular calling features, at an attractively low monthly rate when compared to traditional phone service. However, at this time VoIP is not fully regulated by the Federal Communications Commission (FCC), because it is viewed as a service option, not a primary means of telephone communication. Consequently, while there are standards being created to promote uniformity, there is nothing mandating that all VoIP service providers abide by these standards. The process of transmitting voice as digitized data used in VoIP has created an unreliable means of communication between security systems and monitoring centers.

Many VoIP suppliers actually specify in their literature and web pages that alarm systems should not be connected to VoIP. They encourage customers to keep one POTS line available for emergencies, such as 9-1-1, which also does not always work through VoIP.

What you need to know about AT & T U-verse?

Prior to your AT&T U-verse Voice installation, AT&T strongly recommends that, you notify your alarm company of your switch to AT&T U-verse Voice service and your scheduled U-verse installation date in order for your alarm company to test and check the status of your alarm system with you prior to installation and once installation is complete. You will be responsible for testing your home alarm system with your alarm company after installation of AT&T U-verse Voice is complete, and on an ongoing basis.

If your alarm company determines that your existing alarm panel does not work with AT&T U-verse Voice, your alarm company may be able to install an alternative alarm panel that will work with AT&T U-verse Voice, or a panel that uses cellular phone service, or an IP-based panel that uses your Internet access service. (Talk to your home alarm company about these alternatives and any additional equipment and/or monitoring service charges). Note: If your alarm company installs an IP-based panel that will use AT&T U-verse High Speed Internet as the communications pathway, you must ensure you have functioning battery backup power for your Residential Gateway (and your Optical Network Terminal, if you have one) for your high speed Internet service to work with your alarm panel during a power outage. See learn more about AT&T U-verse Voice and Residential Gateway with Battery Backup.

What is Vonage?

A telephone based monitored alarm system uses a phone line to contact a central monitoring center in the event of fire or a break in. The monitoring station usually tries to contact the homeowner to verify the event prior to contacting the police, fire department, or ambulance.  Vonage does not support the use of a telephone based monitored alarm system, and recommends against using a telephone based monitored alarm system with Vonage."

Additionally, it is important to note that while Vonage may work with a home alarm system, we do not recommend it. If for any reason you lose your Internet connectivity - due to a power outage or problem with your Internet service provider, for example - Vonage will not work, and your alarm system will not be able to make an emergency call if it is triggered. For this reason, we recommend you keep a basic traditional landline dedicated to your home alarm system and use Vonage for the rest of your calling needs.

What is Comcast?

Comcast Digital Voice works with most modems, home alarm systems that use tone dialing and standard data protocols. Comcast does not guarantee that the Comcast Digital Voice (including, without limitation, the feed between the alarm panel and the Comcast-supplied eMTA) will be uninterrupted or compatible with each and every make or model of home alarm systems.

Comcast advises customers prior to installation to contact their alarm company to inform them of the installation date and time. Your alarm company should arrange to be available on day of your Comcast Digital Voice® service installation.

What other services may not work with my Security System?

(If the service is not listed, please make sure to contact the office to verify if it will affect your system prior to getting the service installed)

  • VoIP
  • Verizon FiOS
  • Vonage
  • Comcast Digital Voice
  • TriplePoint Bundles
  • Digital
  • Fiberoptic
  • Magic Jack


What services is my system compatible with?

  • Time Warner
  • Charter
  • Analog Telephone Line

If you get one of the following services, make sure to get a UPS back up power supply for the computer and modem. This package should cost approximately $100 - $150 and up.


What our Competitors are telling you VS. the Truth:

Most competitors are telling you they are compatible with any type of service you get. No Line, No problem, is a lie! No Security company is compatible with VoIP, U-Verse or any TriplePoint Bundles. However, they will try to convince otherwise by offering you other alternatives of monitoring. This does not mean they are compatible, it simply means they will have to find a different method of monitoring your Security System.

These new types of bundle services have greatly affected the security industry. We are continually researching other cost effective methods in which to monitor your security systems. To date, the most reliable method of communication is an Analog telephone line. However, if you have already gotten one of the following services installed we offer two alternative methods of monitoring. Please see below:


What alternative methods of monitoring do you offer if I have already gotten one of the above services installed?

Option 1. Internet Module

The Internet Module is connected to your internet network either by running a cable to your router or by installing a wireless network connection. It transmits all signals solely through the internet. No telephone line is required.


  • Does not increase your monitoring rate
  • Charter
  • Analog Telephone Line


  • Installation Cost
  • Your internet has to remain on 24 hrs a day
  • If you only have the internet module and no phone line, we will not be able to communicate remotely with your panel, which means we will have to arrange a service call to make any changes to your system.
  • If your internet is down, your security system is down leaving your home vulnerable.

Option 2. Cellular Wireless Radio

The cellular wireless radio works independently of your alarm system. It has a separate power supply and back up. All secure and encrypted signals are transmitted wirelessly through advanced GSM cell phone towers.


  • If you do have a phone line, the cellular radio still transmits signals.
  • You do not have to pay the additional cost for an Analog telephone line.
  • There are no phone lines for the burglars to cut.
  • Remote monitoring and web control of your security system.
  • You can arm/disarm via computer and cellular phone.
  • Customized text and email alerts.


  • Installation Cost
  • Increases your monitoring rate
  • If you only have the cellular radio and no phone line, we will not be able to communicate remotely with your panel, which means we will have to arrange a service call to make any changes to your system.
