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:

Subject: [Asterisk-Users] Intercom system (not paging system)
I've looked around and found previous discussion about this, but so far I
have not seen any answers that really solve this problem.
I'd like to integrate an intercom system into Asterisk so that users could
dial an extension, the phone on the other end would emit a beep, and then the
speakerphone would activate letting two people have a conversation without the
person at the extension picking up the phone. This is a huge benefit for an
office/warehouse environment.
I know that this can be programmed with certain Cisco phones (set to
autoanswer), but my problem is that the phones that I want to do this with are
down in our warehouse and I think the Cisco phones would be stolen quickly.
I've also thought about a writing a software solution with microphone and a
set of speakers, but, again, the computers would probably end up getting stolen.
A $20 analog speaker phone would work great if I could wire the speaker phone
to pick up the line automatically on ring and then hang up the line on
disconnect. Anyone know how to change the wiring to get it to work?

[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
