The promise and strength of SIP is not VoIP, but rather something much larger than broader than voice services over the Internet. Because SIP is media-type agnostic, by leveraging the existing Internet standard called RTP, or Realtime Transport Protocol. Once SIP is used to establish a communication session between two or more endpoints, the media channels established among the various endpoints all run over RTP.

And because RTP is media agnostic, SIP User Agents and applications can send and receive any type of multimedia content, making SIP into a Multi-Media over IP protocol.

In the press, there have been VoIP related acquisitions, such as eBay and Skype (who do not provide an industry standard implementation), as well as new SIP-based services, or intent for new services. The industry trend towards adding voice-enabled IM capabilities to their existing IP network services will be interesting initial steps towards a much larger business value proposition.
