The launch of Google Voice has the internet all a-buzz (pun intended). But despite all the hype, the real meat is in the call routing features of Grand Central – where you call one number and it rings all the other real life numbers you have according to some simple rules. For example if it can tell it is a work call, it won’t ring your home phone.

But most of this functionality has been available for a while elsewhere and we still recommend a paid Skype account for much of this. Get a call-in number and a call-out number, then set up your routing. The rules are less sophisticated than with Grand Central, but most people using a system like this really WANT to be reached anyway – that’s sort of the point of call routing.

Yes, Google Voice is free within the US, but for how long. Skype did that for a little over a year and then moved to a really low cost paid model. Plus Skype gets you better conferencing and video calls thrown in.

But here’s the real trick. Most people now have mobile phones for work. So why have a company switchboard if you are a small, up-to-date and smart business? Setup a central Skype or GrandCentral number for everyone. Forward calls to cell phones or answer via computer if you are at it. Skip the expensive business call completely. Many businesses are trying this out, and it can save a LOT of money, but there are two caveats. First, are most of your people on cell phones? If not this may not work. And second, you and your coworkers have to be willing to put in the time to learn and make best use of the system. If you aren’t, then business phone service is for you – you can find some of the best deals here.
