This is just basic plenum 20/2 solid core. Aiphone intercoms don't require anything special for wire - I've used station-Z (20/4), I've used various types of shielded and unshielded 18/2 and 20/2, stranded and solid, I've even seen 16/2 line cord used in a pinch. Can't recall ever having used Cat5e, but I can't see any reason that wouldn't work as well.
There really is nothing special with an Aiphone intercom - it's a single pair driving a speaker, and the call button just signals by shorting across the speaker.

Do you have an account with ADI, Anixter, CSC/Wesco or another wire distributor?
There is nothing terribly exotic about that spec. Any counter person worth their paycheck should be able to quote you an offset.
Perfect. We do and will check in the morning. Thank you for your input guys, it is appreciated.

I don't want to pay $600ish dollars for a box when I'm only using about 100'...
Were you really quoted $600? That's seems crazy!
Here's one for under $100 for 1000ft.

$600ish is highway robbery. A photography store with which I'm familiar sells it for almost half that.
Besides, you don't actually have to use 20/2. 18/2 is fine, and cheap as dirt. If you comparison shop, you should be able to find it for about a hundred bucks a spool or less.
Thanks guys. My concern was originally for the low/mid capacitance, parallel cable, etc. that Aiphone states is required. To be honest about my strengths and weaknesses, I have always found programming systems standardized in cat5e/cat6 and telling the system what to do much easier to master than using standard cables and making it work the way I want.
By the time I entered this industry on the system building side, much of the systems were being replaced with category cable and I don't had a solid foundation in some of the older technology where understanding cable properties (other than category and fiber) was mandatory. Should I, yes, and I can understand general necessary needs, but I can't tell if Aiphone's claim of specific cable properties is necessary for operation or just a marketing ploy to purchase their overpriced cable. Realistically this is probably why I shy away from audio system design (no really, this was just a moment for me).
So in the most round-about way possible, my question is whether Aiphone's cable requirements are necessary or not, keeping in mind my system design includes audio and video. Thank you.

Robb, where does the requirement for 872002P10C come from? Just browsing the JP series I could find references only to 18 awg, not 20.
Is it a higher performance substitute for added range or reduced size?
If you do decide to go for 872002P10C, a certain photography store seems to have it pretty cheap at $344, comparatively speaking that is.
As Keefe says standard cable is going to work, though Aiphone would no doubt argue that there would possibly be high-frequency attenuation, which could reduce intelligibility.
One would really have to listen to know for sure...

Looking at the installation manual it says the 20 awg, mid cap cable is good for up to 100 meters. It has a capacitance of 18pf/ft. Since you are running less than 1/3 of that distance, you should be fine using a standard 35pf/ft cable instead, as far as total capacitance/resistance go.
