Looking for new business models applied to voice services

Alec Saunders, commenting a post by Gary Kim, discusses how the availability of voice inside many applications is actually changing the business model applied to more traditional voice services:

The challenge for the voice service provider is in delivering value that can be monetized for more than a few tenths of a cent per minute. The service provider must become a pipe for delivering huge volumes of communications, and/or an applications provider that leverages that volume.

The new Iotum's application for conference calls inside Facebook is a great example, indeed. Another case that I'd like to mention is the Abbeyphone's VoIP extension for Firefox: always available while browsing, you can place a call wherever you find a telephone number.

And what about you? What's the most useful voice application integrated into another?
