摘要：
An implementation of a voice-over-Internet protocol (VoIP) system for accomplishing two-way, three-way and conference calling between two or more parties is disclosed, in which new call features are readily adapted. The VoIP system is implemented in a Session Initiation Protocol (SIP) framework in which aspects of Distributed Feature Composition (DFC) architecture are modified and applied to overcome known limitations in the adaptability of existing VoIP frameworks.
