Alarm System Compatibility

VoIP2Go treats calls from monitored alarm systems with a higher priority and is compatible with all Alarm Monitoring Centers in North America.

Many Alarm Companies have made it very difficult and expensive for their Customers to migrate their systems away from phone lines. Many tell their Customers that their systems will not work over the Internet, they charge a lot for Internet or Cellular equipment upgrades and then insist they have to increase their monthly charges.

Don't fall for it! Your security and medical alarm system will work perfectly well with our VoIP2Go Alarm Line add-on. We have many happy Customers using our service to transmit alarm signals to ADT, Reliance Protectron, Monitronics, Bay Alarm, Sonitrol, Stanley, Slomins, Vector, Protection One and more. It doesn't matter who your Alarm Company is - VoIP2Go will get your signals there!


Some of the ADT Customers that have contacted us have been quoted as much as $800 up-front to upgrade their system plus an additional $8 per month service fee. They have been assured that monitoring service will not work over VoIP. Well, we beg to differ. If your ADT alarm system is not working over your existing VoIP service, then you've come to the right place.

VoIP2Go Alarm Line feature has been in use since 2009 by Customers of ADT and other Alarm Companies for monitoring their security alarm systems over the Internet. The technology has been proven over a long period of time with all the common alarm panels used by ADT and others. The technology supports all alarm formats so whether your alarm panel is brand new or 30 years old, it will be able to reliably send signals to ADT. Our service is not approved by ADT, but it is certainly approved by many ADT Customers that we have helped out over the years.

To get started with our ADT compatible VoIP service, simply place an order for the VoIP2Go Alarm Line feature and we will send you a Black Box with one port for making regular phone calls and another port for connecting your alarm panel. Calls leave your home or business over your Internet connection and we connect them direct to ADT or any other alarm company you chose. As alarm signals arrive in exactly the same way as they did when you had a regular POTS landline, it is totally transparant to the Alarm Company and they are none the wiser that you have switched to VoIP.

With our simple 'Plug-n-Call' setup, there's no need for you to worry about anything related to equipment or service setup and configuration. Of course, you are welcome to bring your own Cisco device and download our custom firmware into it. Either way, your alarm system will be able to make calls to ADT or any other Central Station just as reliably as it did over your old phone line. There are no changes required at ADT in order to get your alarm monitoring working again.


Monitronics state on their blog that VoIP is a risky option for home security. That's because they don't know about the VoIP2Go Alarm Line feature that allows Customers of Monitronics to switch to VoIP Phone Service without any interruption to their alarm monitoring service.

All of the warnings about using VoIP services for monitoring alarm systems are valid as VoIP providers optimize their networks for voice communications and not data communications which are required by security and medical alarm systems. At VoIP2Go, our roots are in the electronic Security Industry and we have an in depth understanding of what is required to reliably transmit alarm signals over a VoIP network.

The VoIP2Go network was built from the ground up with alarm systems as the primary concern. We tested dozens of different manufacturers VoIP equipment and dozens of VoIP networks over a number of years before we found a combination that would work reliably.

We understand that there needs to be dial tone each and every time your alarm panel has to make a call. We use a combination of DNS SRV technology, geographically redundant servers provided by multiple VoIP Providers and a comprehensive plan of action to defend against the denial of service attacks that are so common in a VoIP environment.

Monitorincs are a well respected alarm company and like the majority of companies in the Security Industry, they know their business. Unfortunately, the alarm monitoring industry does not have an in depth understanding of voice over IP technology and has taken the easy way out by recommending cellular communications in almost every situation. This may be a profitable approach for Monitronics but not necessarily the most cost effective method of switching to VoIP for their Customers.

VoIP2Go have many Customers using our network to monitor their Monitronics alarm system over their Internet connection, so you will be in good company if you decide to make the switch.

Protection One

If you have an alarm system monitored by Protection 1 over your regular telephone landline and you'd like to switch to VoIP, then the VoIP2Go Alarm Line feature will allow you to do that without any interruption of monitoring service. There's no need to pay for a Protection One technician to call out and install costly new cellular equipment when it's really not required.

Protection One may try to convince you otherwise because it is not profitable for them to allow their Customers to switch to VoIP. It's much easier for them to jump on the Security Industry band wagon and simply state that alarm systems do not work over VoIP. That statement is partially true of course when using regular third party VoIP providers who's networks are optimized for crystal clear voice. Alarm systems send signals via data and the methods used to achieve clear voice communications have negative effects on alarm monitoring.

We have many happy Customers using our service to monitor their Protection One security or medical alarm systems. All you need is a Cisco or Obihai ATA that you can order from Amazon for under $40. Connect your Protection 1 alarm panel into one end, connect the other end into your Internet equipment and setup is complete. The SPA112 and Obi202 have two RJ11 phone ports. You connect a regular phone handset into port 1 for making phone calls via the VoIP2Go phone service and connect your alarm panel into port 2 for alarm monitoring.

Ever considered Self Monitoring?

Self Monitoring seems to have three main benefits:

1. A method of filtering which events get forwarded to the Central Station. As an example, end users can receive email alerts for open/close signals and reference all events online at any time without them being passed to the CS. This can represent a huge cost saving for some clients. It's just more convenient for others.

2. Add on features either not available from the Central Station, or too costly. As an example, Customers using the VoIP2Go platform can add any number of IP cameras (4 free) to their account and record images using a wide range of parameters.

3. Central Station Failover. Customers like the idea of having an additional level of redundancy. Some like it as a way of checking up on the response times of the operators. Alarm signals arrive at the CS and in our platform simultaneously, so the CS cannot pull the wool over the Customers eyes. That one feature alone makes it very unpopular with many in the monitoring industry.

All the usual warnings related to power and Internet outages apply and you should always have a backup plan for when things go wrong.
