Ran cables for a door intercom unit. They are going to tile around my cables and just found out it's going to be glass tile, so I'm gonna have to mount the intercom on the glass tile. What's the best bit to use in this case to drill for an anchor?

If it's solid glass I'd probably make a template and have those who are installing the glass drill my mounting holes.
If you're talking a glazed ceramic tile a good masonry bit, slow and steady.

I would add to Bill's excellent advice this note for glazed ceramic tile:
With a sharp knife or flat bladed screwdriver - scratch the glaze at the spot you're going to drill, this will give the bit something to bite on and prevent it from wandering all across the tile. And as Bill said, a sharp masonry bit, low speed, no hammer.

Thanks, the owner said glass but I'm guessing it's glazed ceramic tile. Thanks a lot for the tips fellas...

A friend of mine who owns a sign shop introduced me to some insanely-strong double-sided rubber tape that they use for affixing lettering to strange surfaces. It really works well, but be sure that you have your location accurate. That stuff is very unforgiving.

That would be Butyl rubber tape and it will stick to glass permanent. Tape will work as long as the object is not to heavy or area very hot. It may sag over time so it best to have at least one anchor which can put into the grout. Butyl tape can be found at most auto parts stores or window repair shop.

That must be the same stuff they use here to attach signage to walls for classrooms and offices. It's a real pain to scrape off the plastic and/or the wall.

What Skip said. If I could, I would try to do it this way: 1] Mount the box first. 2] Have them tile around it. 3] Talk to the tile guy, and convince him not to butt the edges of the tile tightly against the box, instead leaving about 1/16" or 3/32" gap to allow for thermal expansion. This may sound overly cautious, but if a crack develops in the tile right next to the box in the future, the customer is going to blame the phone guy. 4] Have the tile guy apply whatever flexible bead seal around the gap that he recommends. This conversation I would try to have in the presence of the customer, so when the bead dries out in ten years and it needs to be re-caulked, he calls the tile guy and not me. If I sound overly paranoid, it's because I am. I have seen mirrored glass tiles in up-scale buildings that cost about a hundred bucks per tile, and I sure wouldn't want to get the bill to replace those.

Like Jim says EXCEPT: a) I'd use longer screws to mount the box b) Have the tile installer loosen the screws and tile behind the box almost up to the screws c) Re-tighten the screws
That way if the box needs changing later and it's a slightly smaller model, there will be no gaps.

I would prefer the box not touch the tile if it where my job , also I wouldn't trust the tile guy to loosen and re-install the box

After thinking about this a little more, a different plan comes to mind: Furnish the box to client, and ask that they have their tile contractor handle the mounting. Just make it clear that the final installed unit will be fairly heavy, and that you need a hole behind/through the box for cabling. I would pre-drill the box if required, and maybe furnish a short stub of PVC for the wall penetration.
This puts all the tile-related aspects in the hands of the tiling contractor, which may be better than getting into a conversation about expansion gaps and sealers that could be perceived as telling them how to do their job. Besides, they may have a recommended method of mounting something like this that I have never even heard of!
If the customer hires a trunk-slammer tile guy, and you come back to find the box stuck to the wall with duct tape, then I would just get them to sign a release [I know, that is easy to say now, but in reality...]
