Many people use IP Phones at home. A very popular phone is the Siemens Gigaset product range, which provides analog line as well as VoIP/SIP connectivity. Models C470IP, C475IP, S675IP and S685IP are currently in the market.
But .. how do you connect a door intercom or door station to them ?
Fortunately, the latest SIP firmware for the Annuncicom makes a perfect companion for the Siemens Gigaset IP phones, it can talk with the Siemens phone via IP !
- A visitor, who presses the “ring” button on the phone, places a SIP call to the Siemens base. This can be done “peer-to-peer”, so it won’t consume an account entry, and it does not need a PBX or server to work.
- The DECT phones will ring, indicating a call from the IP address of the Annuncicom
- The user can answer the phone talk to the person in front of the door, and also open the door by typing a configurable number sequence on the keypad (for example, “11”).
- Even multiple Annuncicoms can be used in this fashion, for example, for front door and back door !
The solution works, of course, also with other SIP PBXes like Asterisk, but the beauty with the Siemens IP phones is that there is no servers, no PBX, only little configuration needed.
