| | Session Initiation Protocol - Wikipedia, the free encyclopedia |
 | | Others would argue that SIP is a stateless protcol, hence making it possible to easily implement failover and other features that are difficult in stateful protocols such as H.323. | | | The protocol was further clarified in RFC 3261, although many implementations are still using interim draft versions. | | | The free OpenWengo softphone and the proprietary Gizmo Project have implemented SIP in their clients and services. |

| | SESSION INITIATION PROTOCOL |
| | SIP is a very simple when compared to its counterpart H.323, which is inherently complex and has many overheads. | | | When the SIP server is queried about the location of a callee, it returns a list of possible locations. | | | As SIP has been designed by keeping Internet in mind, it avoids the extensibility pitfalls. |

| | Although SIP and H.323 can also be used to communicate to limited intelligence end points, they are especially well-suited for communication with intelligent end points. | | | For more information, see RFC 2543—SIP: Session Initiation Protocol, which can be found at http://www.faqs.org/rfcs/. | | | User agent server (UAS)—A server application that contacts the user when a SIP request is received and that returns a response on behalf of the user. |

| | Despite such high hopes, there are concerns that SIP could pose network security problems as it becomes more universal. | | | In fact, the company is already working with Microsoft on a beta version of a Windows XP server supporting SIP, says Henry Sinnreich, a distinguished member of engineering at WorldCom. | | | In one significant move, Microsoft Corp. built support for SIP into the Windows XP operating system. |

| | SIP ( Session Initiation Protocol) |
| | If your phone software says it supports SIP, what it means is that means it is able to use that protocol to talk to a server or router which will do the job of connecting your call. | | | Many devices support only one of these protocols, so ensure you check that all the devices that you buy use the same protocol as each other and your service provider. | | | The session itself could be used for video, multimedia conferencing or gaming, or of course for an IP phonecall. |

| | SIP (Session Initiation Protocol) |
| | That lets SIP user agents provide more features and operate in more of a peer-to-peer fashion. | | | Session Initiation Protocol was developed in the mid-1990s by the Internet Engineering Task Force as a real-time communication protocol for IP voice, and has expanded into video and instant-messaging applications. | | | The SIP model for telephony puts most of the intelligence for call setup and features on the SIP device or user agent - such as an IP phone or a PC with voice or instant-messaging software. |
