IM Driving VoIP

You might think it's services like Vonage that are driving VoIP use among consumers.

Instant messaging is much more important. Many instant messaging services have added VoIP connectivity, and the marriage of IM and presence with VoIP is very natural. In fact, the best-known VoIP service, Skype, is as much an IM network as a VoIP service.

The number of regular users illustrates this:

  • Vonage has about 2 million regular users.
  • Skype says it has over 110 million "customers." It probably has about 30 million regular users, of which about 7 million are online at any time.
  • AOL, MSN, and Yahoo perhaps have another 50 million regular VoIP users.
