Outdoor Asterisk SIP door phone / VoIP intercom
The three main applications for the outdoor Asterisk SIP door phone are as follows. 1: New build End User sites with an Asterisk based IP-PBX installed. 2. Same as the former but they are using a hosted VoIP solution. 3: Where customers require asterisk door phones when they upgrade from an analogue phone system, to a SIP/VoIP based one. In this instance their analog intercoms may no longer work and they require a SIP door phone asterisk based solution. One with effortless integration and high quality full duplex audio.
Asterisk SIP Door Phone requires NO more hardware
The Asterisk VoIP intercom is made by CyberData corporation (distributed by iEntry Systems). This is a high end product with mass Interoperability testing, verification and certification. Asterisk is one of 35 IP Telephony Manufacturers who have approved the product. If we look at other high end True SIP door phones and intercoms, they can range up to £1500. Most require several system parts to complete the system. The Asterisk SIP door phone needs a POE switch and nothing else. Well, obviously the cat5e or cat6 cable to connect it. If you need 4 x SIP door phones, you will need a 4 port Netgear/HP switch. Thats it, no running software, no PC required, no tied in handsets.

Opening Doors, Gates and Barriers
The Asterisk voip intercom features an integrated DTMF controlled relay. Dual Tone Multi Frequency is the signals our telephones send when we press a number. Through its web-page settings you would program a 3 digit DTMF string. For this example, lets use 888. Within the settings you would pair an extension/telephone number to the Push to Talk button field. The door phone would place a call. If the End User wanted to grant access, they would hit 888. This then opens the door gate or barrier.
