Door phones can be directly incorporated into Telebroad's PBX system, allowing for handling of guests and workers traffic into your office without having to invest in an additional system.
Note that a compatible door latch needs to be installed in order for the door phone to be able to remotely open a door. This is not done by Telebroad, but by a knowledgeable locksmith.
See explanation of Door Phone Features for the following tables at the end of the article.

Extra requirements for installation
See our installation guide for more information on these.
ATA: A device that enables analog door phones to connect to a regular IP network/phones.
SPA 112: A type of ATA device made by cisco.
SRC-1: Enables an analog phone to securely control a door strike or gate controller at a remote location. The SRC-1 has a feature to eliminate the possibility of someone dialing the activation code through the entry phone using a handheld touch-tone dialer.
POE Injector: A device that adds power to an Ethernet cabling for consumption by devices compatible with Power Over Ethernet (PoE) but that are connected to network equipment that does not provide POE. In other words, in such a case the network only provides data and the POE injector provides the power.
Explanation of Door Phones Features
Door phones have several distinctions to consider:
- Keypad: The most apparent distinction is if a model comes with a keypad or not. A keypad adds the functionality of a guest being able to dial different extensions in an office or workers able to dial a code in order to enter the office. A door phone without a keypad can only dial one extension, usually to a receptionist.
- IP/Analog: An IP door phone can directly interact with Telebroad's PBX system just like any VoIP phone. An analog door phone will require additional hardware to convert analog signals to digital signals in order to achieve the same interaction. IP door phone is therefore a somewhat more economical choice, but it really depends on the existing wiring that runs to the physical location of the door phone.
Another advantage of IP door Phone is POE – Power Over Ethernet. A POE phone does not have to be plugged into a power outlet to operate and instead receives power directly from the Ethernet data line. By nature an analog phone never offers POE.
Analog door phones also require a separate purchase and installation of a remote controller unit, like Viking SCR1, to facilitate the remote opening of a door. - Indoor/Outdoor: The physical construction of a door phone would determine if it is weatherproof and tamper-resistant or not and hence if it can be used outdoors on not. A door phone that is placed in an indoor environment (like a corridor just outside an office), would not require any special protection from the weather. A door phone that is placed in an outdoor environment does require additional weatherproofing, a rain cover and water resistant keys, as well as a tamper resistant materials and construction.
- Camera: A camera enables a door phone to send a video image of a guest to the receptionist or other office personnel. Video signals either require additional cabling or an IP connection.
