Motley Fool did a story on VoIP and it was optimistic as you would expect. No surprises in here just some fairly obvious commentary. Still a good overview of VoIP investments and i am generally a Motley Fool Fan. Here is an excerpt:

Although this technology has been around for years, the high-speed Internet connections required for VoIP were not widely available. The long-distance carriers didn't see this coming in the early days, but now it has caught their attention. Privately held Vonage -- which has more than 300,000 subscribers -- is the undisputed king of commercial VoIP providers. But it's unclear how long its reign will last. In a move to keep customers, AT&T (NYSE: T) offers its own version of Internet calling while discontinuing traditional long-distance service to residential customers.

Not be left behind, other carriers are vying to jump online (pardon the pun). Verizon (NYSE: VZ) and BellSouth (NYSE: BLS) have launched VoIP calling services, while SBC Communications (NYSE: SBC) will begin selling residential phone services that use the Internet this year. The company is aiming for its existing customers who have broadband access but gave up their landline phones. SBC's entry into the residential VoIP market helps validate industry analysts' projections of about 10 million U.S. homes having a VoIP line by 2010.

The cable companies are also getting up to speed by advertising "triple play" packages of voice, video, and high-speed data service. They hope to close the considerable subscriber lead Vonage once had. More than 200,000 people now get their phone service from cable provider Time Warner (NYSE: TWX), which says it is adding 10,000 new phone subscribers every week. Comcast (Nasdaq: CMCSA) recently announced plans to roll out its service later this year.

Not only will the service providers see profits from the switch to Internet-based phone traffic, but also equipment makers such as Sonus Networks (Nasdaq: SONS) have seen demand for their products rise sharply. Sonus recently announced a 67% increase in customer traffic from last month on its Internet networks. Recent deals with companies such as Samsung Electronics -- the world's third-largest handset maker -- could make Sonus a successful player in the wireless VoIP market, too.
