SIP is being embraced today by all major communications equipment manufacturers and many software companies. Because SIP is an Internet Engineering Task Force standard, it is inherently an open architecture, which serves to quicken its acceptance. The protocol readily enables voice and data convergence and is quickly becoming the protocol of choice for always-on integrated communications, adding rich media collaborative capabilities to business telephony and customer contact environments. Presence and the integration/interworking of SIP into desktop and business applications are central to the virtual enterprise, simplifying workflow, lowering transaction costs, enabling faster decision making, and improving customer and employee satisfaction.
