"AT&T WebService Connect allows different applications from different sources to communicate without time-consuming custom coding. And because it is XML-based (define), it's not tied to any one operating system or programming language.

Developed over the last year with partner Grand Central Communications, WebService Connect plays into AT&T broader strategy of evolving from a long-distance phone company to a provider of enterprise network services. "

...

"The service will be rolled out gradually in the coming months. It starts at about $34,000 per month, although prices could run higher depending on usage. In terms of its telecom competitors, AT&T believes it is farthest along in offering Web services (define) to its customers. "

Congratulations to GrandCentral!
