By 2012 almost half of all telecom users will be using at least one SIP-based service, but more than likely will have many services from multiple devices able to communicate with other users and services across the Web and between enterprise and public networks. This will generate over $150 bln in service revenue annually with cumulative infrastructure capital expenditure of over $10 bln by that date. By 2012, ABI Research expects almost 1.2 bln VoIP users to be active, most users also subscribing to several forms of messaging and video sharing driven by the interest in user-generated content. Additional services supported by SIP will include presence, click-to-dial, buddy lists, email and Web access which are assumed to be ?core? services and will be included as standard in any service offering, and bundled with broadband access.
