| A SIP trunk is a service offered by an ITSP (Internet Telephony Service Provider) to use Session Initiation Protocol (SIP) to set up communications between an enterprise PBX and the ITSP. A trunk may include multiple voice sessions (as many as the enterprise needs). While some see SIP as just voice, SIP Trunking it can also serve as the starting point for the entire breadth of real-time communications possible with the protocol, including Instant Messaging, presence applications, white-boarding and application sharing. The potential for a rapid ROI is a key driver of SIP trunk deployments. However, maximum return on investment can be achieved when you extend VoIP outside of the corporate LAN. In terms of infrastructure purchases, SIP trunks provide an immediate cost-savings. They eliminate the need to purchase costly BRIs, PRIs or PSTN gateways. Audience:
