ABSTRACT:
A method and system for enabling voice over Internet for computer applications includes registering session initiation protocol (SIP) as a system service and providing SIP service through an application programming interface (API) to permit access to service functions by individual software applications. A SIP link is provided within a software application to permit user invocation of SIP service functions. The link may be passed as a parameter to permit external access to an invoked service function.
