IP Convergence: Beyond VoIP, Beyond Cost Savings

OK, so Web Services has been around for some time now.  XML and SOAP have been used as an easy to implement mechanism to serve as an API for distributed applications.  However, only until the last year or so has web services come to the forefront of telecom services, and I believe it will be used as a foundation for many innovative solutions that will be built under the Unified Communications/Integrated Communications umbrella.

VoIP has traditionally been relegated to basic telephony services in the telecom industry, such as VoIP/SIP Trunking and Hosted IP Telephony services.  However, with the advent of Unified Communications (check out the Unified Communications Conference at the Fall VON Show in October), which brings together telephony, messaging, collaboration, data and mobility into an integrated solution, we begin to see services using VoIP as becoming more visual in nature, bringing telephony into web interfaces rather than to phones, and using multiple distributed applications which are blended to create solutions.

Global Crossing has announced that it is providing innovative Unified Communications solutions to the UK Government.  These services will soon be expanded to provide even greater capabilities to the Enterprise, and globalization is a key element of this strategy.

Does this mean IMS?  Not necessarily.  Many solutions in the market have built interoperability through vendor partnerships using SIP from a voice signaling perspective, and Web Services brings another element into the mix which greatly improves interoperability and improves usability.  IMS is not nearly as innovative as Web Services, and certainly not as easily implemented.  However, IMS can be combined with Web Services to anchor control, signaling, and provisioning of multiple applications in a standardized fashion.  My belief is that it will take the industry some time to pull everything together using IMS.

As an example of how web services can be introduced into telephony, clients can be built into web pages using internet API's which use click to call functionality.  In addition, web services can be used in a unified communications "Dashboard" interface where a user can view presence status, conference attendance, manage services through voice portals, and trigger entirely new communications business models.  Two innovating vendors highly leveraging web services in the telecom space are Sylantro and Iperia, which bring call control and management extended to web communications, and provide visual voicemail and unified messaging services as a solution.  Very cool stuff.

Web Services brings easy programming interfaces to industry standard transport (HTTP) to bring innovation to telecom services.  As enterprises become more distributed in nature, with remote offices in multiple countries, their key workers are also becoming more distributed and mobile.  Telecom needs to keep up with these trends and the increading demand for requirements of the changing workplace with real time communications.  This is bringing traditionally separate applications together via Unified Communications, and the "unification" or blending of these distributed applications can use a combination of signaling techniques and web services functions to bring a highly visual element to the solution.
