Hi, Does anybody know of a VoIP compatible doorbell or door intercom unit? I've contemplated buying a cheap SIP phone, ripping it apart, and putting it inside an IP66 sealed unit... It would need: - At least one speed-dial key, or some way to make every button dial the same extension number - PoE (power over ethernet), so I can power it off the central switch - cheap enough to rip apart Any ideas? Also, is there anyway in the Asterisk config, to ensure anything dialed from the phone in turn just dials a specific extension? What I'm thinking: Door bell button rings extension 8888, which rings all phones. Caller ID is "Front Door Entry" or whatever, and the Cisco's Dial Plan has a doorbell chime as the ring tone for this specific extension filter (so 8888 has it's own ring tone). There is a time out of 5 to 10 seconds, which represents the time it takes for a normal doorbell to chime and stop. Now, the intercom bit... If I want to find out who it is before running downstairs, I simply pickup my receiver and ask them. Otherwise, I just leave it and the ringing stops, and the call is terminated. Also, if I want to find out who is outside, I can just dial a special number, say 8889, and I connect to the phone outside. Now, can the phone be set to automatically pickup a call?! Or perhaps, If I find a Cisco 7940 with a damaged case on eBay, I can rip it apart, and then use the SIP/SCCP Intercom feature on that phone only?! Does this sound sensible/achievable?! Best, Ad.
> Hi, >new context for door phone immediate rather than dialtone default extension is whatever you want it to call / do to mine I added the twist of rolling into voicemail if I don't answer so whoever was at the door can leave me a message. I used a cheap analog phone on my channel bank. dialpad on the phone is just ignored. most people still insist on ringing the doorbell though, but at night, I call out to the doorphone to see who is there if I am not expecting anyone.

The combination of a cheap ATA and standard doorphone would seem easier (and maybe cheaper). For door phone hardware check out: http://www.vikingelectronics.com/ Jim James H.

If you combine this with a Cisco ATA186 that will automatically dial a number (dialplan on the cisco) or which goes into an immediate connect (configuration on asterisk) you can do pretty much anything oyu want. However, those doorphones are often relatively expensive... The same can be done with any analog phone, but the interface will be sucky (have to pick up the phone, dialpad which is useless, etc.) Florian
