I’ve been lucky enough to meet with a swath of companies this year, almost all of which excite me on various levels. One of the more interesting infrastructure conversations I’ve had is with a company called Bandwidth.com, who this year in Austin launched a new service over at Phonebooth.com. The service, like much in the telephony business, isn’t immediately exciting (due mostly to the utilitarian nature of telecom), but is really quite interesting at first brush, and looks to have the signs of a service offering with staying power once you delve beneath the service.

Bandwidth is a company that’s been around for ten years, involved (unsurprisingly) in the bandwidth business. Starting out as a reseller, they’ve long since transitioned to owning lines free of legacy traffic of any kind, which allowed them to dip into the VoIP business as well.

The offering this year is certain to shake things up a bit, since they’ve essentially committed to being the Google Voice of hosted PBX, with Phonebooth.com’s free hosting  offering. The site allows the user almost all the options standard in any hosted or non-hosted PBX solution (call attendant, multiple extensions, voicemail, voicemail transcription and such), with the pricing model similar to Google Voice / GrandCentral.

When choosing a hosted PBX solution (or even a unified messaging solution like Google Voice, or VoIP solution like Vonage), the key question generally is: “Will the company continue to exist once the giant companies they’re disrupting unleash the legal hounds?” The answer in this case is ‘most likely, yes.’ Bandwidth is an organization with a proven ten-year track record not only in the infrastructure management business, but technology innovation. Holding patents on key telephony technologies (and having executive leadership with strong legal expertise) has staved off the attacks thus far, and doesn’t show signs of abatement.

Over the course of the week, I think I’ve spoken to just about every executive at the company – yesterday, I spoke with company founder, CEO (and “recovering lawyer”) David Morken, who gave a great synopsis of what they’re doing. Check it out below.
