My parents are looking for some kind of intercom system for their house. This would only have a couple stations (like 3 or 4).

Those 900 MHz wireless ones are out of the question as it must also reach the detached garage which is a couple hundred feet away. Cellular phone service is also spotty in the area in the area (thus the need for the intercom - if my dad is in the garage and my mom wants to talk to him without walking over, cell phone calls often go strait to voicemail)

There is ethernet in practically all the areas that would need to be covered.

I've Googled around for hours and either my google-fu is real weak tonight or I'm just not finding anything.

Are there any IP-based intercom/phone systems that can manage point to point audio communication. I feel that some kind of VoIP PBX like Asterisk is way overkill for this.

Any solutions for this? Ideal device would be something like an intercom that just plugs into an ethernet jack.
