See below for a previous post of mine. It doesn't offer a "dial pad" like most normal phones, but won't get stolen, offers the intercom service you want, and has a big fat button for people to call a "hotline".

[Asterisk-Users] Intercom system (not paging system)
There is an auto-answer speakerphone that might do what you described: http://www.vikingelectronics.com/products/apartmententry/k-1700-3(rd).html Jim James H.

[Asterisk-Users] Intercom system (not paging system)
This may be a way to do what you described with a $20 speaker phone and no phone modifications: Using the speaker phone dial-in to a conference room on the asterisk Then whenever anyone wants to call this extension, you can route their call to the conf room and they can have a two-way conversation. Possible Downsides: * if call from the conference room gets terminated for any reason, then it will have to be re-established manually. * resources consumed to keep conference room open and call always active Possible Advantages: * phone only in auto-answer when you put it in that mode * phone usable to make and receive normal calls Jim James H.
