In this video, you can learn the difference between the standard traditional and the modern VoIP alarm systems. With the Ozeki VoIP SIP SDK and the ContactID handler function the user (like a server) can be notified from every triggered event int he enviroment. Sending/receiving a 16-digit DTMF code from the device to the server allows the user to utilize detailed information like in which zone the event was triggered. In the case of having multiple devices in one zone, the notification sends which device noticed the event, what type of event was triggered and many other options. You can learn how these devices communicate with each other and what you can do to upgrade your current security system to a modern VoIP based wireless security system. Try it today! Download the software and build your own solution today!

ContactID protocol
• Devices send DTMF signals to PCU• Information flows through dial up phone line to central
station• If alarm is not flase the central station notifies the fire-
or security station
Weaknesses of traditional alarm systems
• If an event triggers the PCU send alarms via dial up phone line to central station
• In case a Phone line cut the PCU can’t dial and send the alarm to the central station

• With the help of the periodic ping request user can receive notification about network- and power failure
• In this case the VoIP registration is not successful

• User can setup a unique alarm system where the central station can send notification if the connection is failed with the PCU.
ContactID protocol
• Standard way to notify central station• It is a 16 digit code with the data of the alarm • Contains:– Object ID– Partition ID– Zone ID
• Used by both: Traditional and VoIP alarm systems

Repeat until all events are reported
• Start with a 400 hz dial tone as an invite call which contains the authentication data in dial digits• If central station accepts these 1400hz and 2300 hz tones the ContactID handshake occurs• After the authentication the alarm system sends the ContactID• If the central station received a kissoff occurs.• This process repeats until all events are reported
Try the example
• If you wish to create your own VoIP central station you can do it by using a C# application + Ozeki VoIP SIP SDK
Analog Telephone Adapter (ATA)
• Analog Telephone Adapter (ATA) is used to provide the phone line to the alarm system
• It uses a G 711 codec to digitalize analog DTMF code to digital DTMF code which can be sent through VoIP network.
Switching from traditional system to modern
• Replace old phone line with ATA• Connect your PSTN line to an ATA.• Use G 711 codec to transmit voice
over IP• The central station will receive
notifications through the internet
Solutions you can create using Ozeki VoIP SIP SDK
