VoIP: How Free Can It Be?

VoIP initially promised free calls everywhere, but somebody has to write the software, run the servers and pay the telcos to complete calls to landlines and mobiles, while users need to pay for a phone or a laptop and broadband.

Still, there are many providers of free PC-to-PC calls — Skype, obviously, is the best-known — and they keep coming up with new ways to get users closer to that holy grail of VoIP: free calling. There are enough services that allow free calling at least some of the time — whether via laptop, landline or mobile — that an energetic user should be able to duck paying for a phone call for months by switching services as those services’ restrictions dictate.

Ccube Inc. allows you to make and receive calls without anyone knowing your number. Post a Ccube widget or username on your Facebook, LinkedIn or other social-networking page, viewers click it, your phone rings, their phone rings and you’re connected — all without the caller knowing your phone number or whereabouts, since their Caller ID shows you only as a Ccube number. Ccube also promises 60 minutes of free nationwide (U.S. and Canada) calls per month and an additional 30 minutes for each person you refer to Ccube. This referral business is important to Ccube, which is primarily in the social-networking business. The service matches you with other people based on your (and their) stated preferences, and allows you to meet one another via VoIP. This also means that Ccube lets you block callers and edit feedback that others post about you, to prevent abuses.
