The article presents information on the Session Initiation Protocol (SIP) that is a standard for IP enterprise communications. Over the past several months, SIP has come a long way toward empowering end customers to choose the right products to meet their application, cost and access requirements. Creating customer choice via interoperability is a prerequisite to move IP-telephony forward and will be a catalyst in helping customers migrate cost-effectively--at their own pace--from circuit-based communications to packet based. SIP is an application layer control (signaling) protocol for creating, modifying and terminating sessions with one or more participants. SIP's modular approach, free from infrastructure or architectural constraints, made it ideal to unify the VOIP infrastructure. Simple in nature, SIP became the preferred protocol for communications, besting H.323 and proprietary single vendor schemes. SIP is independent of the underlying infrastructure, making it ideal for setting up and tearing down interconnections over any network architecture.
