What is SIP?
SIP stands for Session Initiated Protocol (SIP). SIP is the “language” that devices speak to setup communication sessions between devices. The communication session can involve voice, video, or instant messaging, and can take place on one of many devices that people use for communicating: laptop computer, PDA, cell phone, IM client, IP phone, etc. After the call is setup, the devices use Real Time Protocol (RTP) for the talk path (just like h.323).
Unlike h.323, however, SIP is not proprietary and is developed as an internet standard.
Why is SIP so important?
SIP builds on a number of existing communications protocols. Developers and system administrators can easily work with SIP, customize it, and program with it. It is rapidly becoming a standard for service integration (how new services and applications are created and combined) within a variety of wireless and carrier networks, and is gaining momentum within enterprises. SIP is being adopted by Avaya, Microsoft, Cisco, Google and others as the standard of interoperability. SIP provides secure, real time communications, including presence, VoIP, video and conferencing regardless of what providers are used.
This growing acceptance in both enterprise and service provider networks offers the promise of a single unifying protocol that will transform not only communications within an enterprise, but communications between the enterprise and its ecosystem of partners, suppliers, and customers.
SIP is a revolution in communications architecture. SIP flexibly connects users, applications and systems – enterprise-wide.
The key factors that are driving SIP’s momentum across all aspects of enterprise communications include:
- SIP simplifies networks: a single pipe to the cloud
- The Result – 30% reduction in telecommunications cost per minute
- 300% return on investment within 3 years
- 9.4 months to pay back initial investment
- Reduce HARDWARE, footprint and power components
