You could hack two standard wall phones to do it. You'd need schematics though. I'm sure you could find an led that would light from the current a normal phone sends to a speaker.
How many handsets are you using? Like how many stations do you want on the intercom?
One will need to be powered. 15v bugger all amps.

Yeah...I know. I just don't want to do a DIY on this. It's one of those things where it would be more expensive than it's worth.

As it stands, I'm already doing a DIY "Recording" light controlled by a switch from a remote location (that's an easy one though.)

These are available on the open market but every place I've checked just doesn't seem to have them (Bradley Broadcast, Markertek, etc.)

I'm thinking a wireless intercom with visual call notification. No cable running, but you need power at both ends.
High noise generation though.
I'm looking and I can't find any intercoms that use handsets..

How many stations do you need?

Love the batphone. Can't you just put a regular pnone under a cone of silence?

Telex make some good stuff, I spoke to a lady who said to do this you would need...
2 * mrt 327 <--- Intercom station.
2 * hs6000 <---- handsets.
1 * ps15 <---- power supply.
Nfi on cost... She gave me a distributor with a phone number with no known dialing code.
Telex distributor in your area plus phone equals answers.

Think of it as a private, mobile talkback system with an indicator.

The more searching I do, the more I think it would be easier to just rig up an extra light on the "recording" indicator showing "put the headphones on..."

It shouldn't be hard.

Of course, if anyone has any other info....feel free.

The Telex stuff is great, but that's a bit more than I was hoping to spend.

So, my current "recording" light is a simple discected 'D' Battery mag light.

On one end, there's a box which holds the batteries, the switch and an XLR chassis mount plug. On the other end, there's a box with a red gel, the flashlight bulb and the receiving XLR mount. With the D battery setup, I can usually get a good 200' and still have it usable. I've thought about using AC power, but I hate needing extra outlets...

I suppose I could adapt the boxes to have 2 switches on one end and two lights on the other - one red and maybe one green. It shouldn't be hard.

Use an led system. Thousands of minutes.
Maybe switch a relay remotely rather than carrying the load through the wires for the switch. Thousands more minutes.
Or feet.

Any good? My sis and I use to have a set kind of like this. I'm sure there are others around. This is kind of neat as well:

TOA use to make a phone systems such as you are discribing but I am not sure if they still do.

I use a pair of AI phones in addition to the speaker intercom that can be seen on my website.
