I agree. What I was asking was, that, back in the day, when I installed mission critical PCs in a telecom environment I tried to use bulletproof equipment whenever possible. PCs powered off the Telecom battery plant were my preferred choice. Now the question:

Are people still using these DC powered PCs anywhere? (I know they're not by me, but I work at a NYC agency). Or are they throwing in a Dell and calling it a job well done?

Sam,

Sun Netra servers can run on DC power. They are stout boxes purpose built for telecom applications, but they cost about 2X than a similar spec'd Dell. They start out a little over $4000 for a x86 compatible box.

HP also offers a DL385 Opteron Server with redundant 48VDC power, which they also market as a telecom product. Search for "Carrier Grade" or "NEBS certified" to find servers purpose built for telecom.

You can actually get ATX-design power supplies that will run off -48, probably in both standard and redundant versions -- though who has *2* -48 supplies?

And there's a whole 'nother stratum beneath "NEBS certified" called "NEBS compliant", which translates roughly as "we designed it to those specs, but we didn't want to pay Telcordia for the sticker".

They're usually somewhere between a bit and a fiar amount cheaper.

Gentlemen, we are drifting off the topic. Please continue with the correct topic.

My bad Ken, sorry.

Sorry Ken, thanks for the moderation. Sam gives out a lot of good info around here so I jumped at the chance to answer a question for him.

Let me steer back to the topic at hand.

The example Sam mentions above is not certainly limited to VOIP but seems to be an all to common problem with VOIP implementations. Someone replaced equipment that was purpose built to run 24/7 in a high temperature, low maintenance environment with equipment that is not. If someone is planning on using PC hardware to run their PBX then that hardware needs to be run in the environment that the PC manufacturer envisioned. In Sam's example it was a power failure, most that I have seen have been problems from overheating.

When someone is pricing out a VOIP setup, especially anything PC based, they have to price out the right equipment for the job and factor the cost of backup power and cooling (and backup power for the cooling). They also can't dump the additional responsibly of maintaining the VOIP system onto the IT department and expect them to run it perfectly because "its based on computers".

VOIP isn't dead, but its not the magic money factory that some business articles make it out to be either.
