SIP is an IETF (Internet Engineering Task Force), internet-based protocol originally designed for call set-up and control. According to the SIP RFC, the protocol defines how two or more end-points can negotiate to set up and control a communications connection that suits the capabilities of the devices and the needs of its users. In simple terms, SIP supports any form of real-time communication regardless of whether the content is voice, video, instant messaging, or a collaboration application. Additionally, SIP enables users to inform others of their status, their availability, and how they can be contacted before a communication is even initiated.
Many companies have made the transition to VoIP; however, most are only using it for communication on the LAN. In this scenario VoIP is only being used as a one-to-one replacement for traditional telephony. These businesses realize a sound return on investment by lowering administrative costs as well as costs associated with calls made within the company. SIP trunking, on the other hand, provides a greater return because it takes VoIP a step further. For instance, full potential for IP communications can be realized only when communication is taken outside of an organization’s LAN. SIP trunks thus eliminate the need for local PSTN (Public Switched Telephone Network) gateways, costly BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces). Furthermore, it directly operates with existing IP PBXs so there is no need for additional hardware.
