emergency phone at a data center. It's usable by anyone. Ever try handing your bluetooth headset with custom earmold to the electrician working on the UPS?
Data centers tend to be noisy in more than just the acoustic spectrum, mobile reception often isn't the greatest.
I wanted to mention that, surprisingly, the cisco 7921 wifi** voip handset (skinny only, so far...), in both g711 and g722 wideband mode (i.e. intra facility paging, noc/colo dialog, etc) has yielded simply amazing results where I've deployed or tried it within colo environments. Perhaps it's the noise canceler within the phone or some white noise-reducing aspect of g722 itself--whatever the reason, results are simply excellent. When the call is within the 'wideband capable' call manager domain, even better results seem to occur (at least that's what staff tell me...). Imagine calling your colo team and not having to repeat yourself due to noise or low-fidelity. Too bad we can't transport this (g722) over the PSTN; perhaps we'd have fewer "oops, I thought you said XYZ should be power-cycled!" experiences with them driving "remote hands" around. -Tk **In colos where I've had the chance to install .11g+.11a WIFI for customer and casual access, the coverage invariably ends up being quite good (stash enough AP1231's on 'clean' spectrum, anything works) -- but YMMV, no warranties, etc.
