SIP: Understanding the Session Initiation Protocol Alan B. Johnston
Publisher: artech-house

I have been speaking about Session Initiation Protocol (SIP) for over two years. And that's what you'll find below: an explanation of what SIP trunking At its most basic level, a SIP (Session Initiation Protocol) trunk acts as a connection between your company and your Internet telephony provider or ITSP (Internet Telephony Service Provider). Introduction The Session Initiation Protocol (SIP) [RFC3261] is a signaling protocol for creating, modifying and terminating multimedia sessions. The standard of its protocol uses open signaling technology to enable communication tools peer-to-peer. At its core IMS uses the Session Initiation Protocol (SIP) for session management, though many compulsory SIP extensions are required to ensure security and reliability. The Session Initiation Protocol (SIP) is another duplex communication protocol that is worth advising in Comet architectural design. Cisco IOS Software contains a memory leak vulnerability that could be triggered through the processing of malformed Session Initiation Protocol (SIP) messages. Session Initiation Protocol (SIP) was developed by the IETF (Internet Engineering Task Force). But you need to understand it, especially if your organization or company is at all involved with the Internet (which nearly every is these days). In that time, I have come to realize the inevitability of SIP in business and consumer communications. Internet-Draft Session Policy Framework February 2011 1. Standards Track [Page 40] RFC 3261 SIP: Session Initiation Protocol June 2002 traversed understand that extension, it MUST insert a Proxy-Require header field into the request listing the option tag for that extension. The Session Initiation Protocol (SIP) allows phone calls and similar communication sessions to be made over the Internet, private data networks, or cellular networks. Internet telephony and chat service provider Skype, owned by eBay, today announced a potentially game-changing move, opening up to the Session Initiation Protocol (SIP) standard for its VoIP services. It enables the delivery of instant messages and the ability of video or voice conferences between unlimited employees via the open Session Initiation Protocols suites SIP. DCF has also eliminated more than 20 percent of all the landline phones in the department and is taking advantage of Session Initiation Protocol (SIP) telephone technology.

Does SIP v2.0 permit to have the protocol running over non-standard ports (not 5060)?
