VON Magazine review of SIP-based products: "SIP turned out to be everything that H.323 was not: a lean, flexible, text-based protocol more in tune with the design philosophy of other Internet protocols .. Users are identified to a SIP system by location-independent, email-like names; e.g., zippy@home.com. And like a browser requesting a home page from a web server, a SIP client sends requests to a receiving server, which processes them and returns proper responses. The SIP messages themselves are very simple, such as "INVITE" (invites another SIP user to a session) and "OPTIONS" (asks a SIP server to reply with its feature set). SIP has kept up with the times. With the rise of Instant Messaging and Presence (IMP) services, another IETF working group developed an appropriate set of signaling extensions, called SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions). SIMPLE is practically a standard, but hasn't yet been finalized as one. Work is also underway to ensure that SIP will function with Mobile IP devices ­ SIP's registration capability lends itself to provide mobility and location functions"  4:10:06 PM  permalink
