Voice Over Internet Protocol (VOIP) Phone Concerns with Security and Fire Alarm Communications Systems

This article outlines the new weaknesses concerned with Voice Over Internet Protocol (VOIP) Phone Service and how it can affect security and fire alarm system communication. VOIP service is much different than classic POTS (Plain Old Telephone Service) telephone lines in that it routes all phone traffic through a digital converter, then over the Internet.   When compared with a POTS line, new concerns are introduced that could affect the stability and dependability of burglar or fire alarm system communication.  It is the intent of Wiring Solutions to make you aware of these potential issues to assist you in making an informed decision concerning VOIP services.   To be clear, Wiring Solutions recommends you NOT rely on VOIP services or Internet-based services for your critical alarm monitoring.  As the technology advances our position may change, but when it comes to the level of protection most people seek you need to be informed of weaknesses in certain types of systems.

Plain old telephone service, or POTS, is the service available from analog telephones prior to the introduction of electronic telephone exchanges into the public switched telephone network. These services had been available almost since the introduction of the telephone system in the late 19th century. VOIP is a very new technology and this list will help reduce the possibilities of failure wherever possible by educating the end user and presenting possible solutions.

Power Supply

The VOIP modem can come as a stand-alone network device, or a combination broadband modem/router/and VOIP converter. This raises new concerns for power supply, as regular phone lines are powered from the telephone company. If the power fails during a storm, blackout, or local electrical problem, the security system will be unable to communicate due to no Internet phone service.  A backup battery solution must be in place so that the modem can operate under power failure situations. Uninterruptible Power Supplies (UPS) can be purchased from any electronics store, or supplied by Wiring Solutions for an additional charge,  and all network equipment should be protected and placed on battery backup. This includes any routers, modems, any hardware required to be powered for the network to function, and the VOIP device as well.

Electronics Failure

The VOIP modem, router, any firewall in place, or broadband modem can lock up or lose signal due to defective hardware or a number of software/firmware issues. This could result in the loss of Internet connectivity or an unresponsive connection. A cable may become unplugged and result in loss of Internet connectivity or phone service.   All hardware must be replaced if faulty, or different hardware purchased if a connectivity problem continues. All hardware should be checked for operation constantly, and, to minimize the chance of loss of alarm monitoring, should be replaced as soon as possible in the event of failure. All cables should be checked and inspected to verify proper Internet and phone service operation.

Loss of Internet Connectivity

The modem could lose signal or connectivity to the Internet, resulting in loss of  phone service. This could occur for many reasons, including, but not limited to, Internet service provider down-time due to problems or maintenance, storm caused problems or damage, lag-time caused by high Internet or local Ethernet traffic, loss of signal due to malicious attacks or network traffic, and the such.  Most of the time, these problems are out of control of the phone customer, and the dependability of the phone service can be down for minutes, or hours, resulting in no alarm communication.  A backup communication route should be explored, the most reliable being the GSM Cellular Backup Service, which relies on the cellular band network and is not affected by VOIP problems such as cut phone wires or loss of Internet connectivity. These options should be considered as a reliable backup system in the event that any failure is encountered by the VOIP service.

Loss of power to accessory devices

VOIP phone service is often tied into a home’s existing phone wiring for practical purposes. This is done either by connecting the VOIP modem directly to the wiring in newer homes with phone connections and network equipment next to each other inside of a closet. Other times a different approach may be taken to introduce the phone system into the wiring. This can be done using a Wireless Phone System which plug into a regular household outlet, and transmit phone signals to other units that are plugged in the outlets throughout the house. If even one of these phone system transmitters or receivers loses power due to an electrical outage or device failure, this means that the phone service is effectively unavailable and the alarm will not be able to communicate.   Consider Uninterruptible Power Supplies (UPS) for all accessory devices and be certain to consider each and every device that would require power for the phone system to be operational. Consider contacting your VOIP Phone Service provider and asking them which devices should be on battery backup so that you can reduce the chances of phone failure in the event of a power outage.

Instability of VOIP Phone Service Quality

When Wiring Solutions connects an alarm to VOIP service, the technician will do everything possible to fully test the alarm signals and program the system for maximum protection against compression artifacts and other problems that could occur while alarm signals are traveling along the digital phone system.  However, this does not mean that VOIP service will transmit alarm signals at a 100% success rate. The VOIP system is highly dependent on other factors such as Internet traffic, Internet hops, lag time, and other concerns which could garble or drop your alarm signals, resulting in no communication to the central station.   This should be kept in mind when purchasing phone service as well as the consideration of a backup transmission method, such as GSM Cellular Backup Service.  Once the alarm signals are converted into digital signals and are traveling across the Internet network, anything may happen to the data to keep it from reaching the central station. Much like a lost email, lost file transmission, or Internet connection problem, this could mean that something as urgent and important as a fire alarm or panic alarm would not be received at the central station due to Internet routing problems. It is strongly advised to consider GSM Cellular Backup service due to the unstable and uncontrollable factors that could render alarm communications useless.


Placing a battery backup solution, checking and inspecting all equipment, and replacing components as soon as possible if bad are some things that can be done to reduce the probability of failing alarm system communications. However, as described above, there are many factors which simply are out of control or non-serviceable for the customer. The VOIP system is a new, emerging technology and is nowhere as dependable as the traditional POTS telephone system, as the new VOIP service is based on a completely new infrastructure.  Care should be taken to protect and preserve what communications exist using this type of phone service, however, a backup plan should be highly considered for a system that protects property, and especially for a system that protects life and property by means of police, fire, and medical panic alarms or automatic fire alarm protection. GSM Cellular Backup Service will allow you to retain your VOIP service and benefits, while having your alarm system or life safety system connected to a more reliable, dependable communications network that is fully supervised 24 hours a day and will alert you to the fact if connectivity is dropped.
