SIP Trunking allows service providers to extend it to other applications such as high-definition video/voice, mobility, conferencing, and presence.
SIP trunks are basically used in three broad contexts: 1) as an interconnection option to the PSTN (public switched telephone network); 2) as a SIP port on an enterprise server that offers interconnectivity between different enterprise servers such as telephony, voice mail, presence, etc., and, 3) for SIP interconnectivity between IP-PBXs, replacing traditional TDM (time-division multiplexing) lines. All the signal processing, protocol conversion, transcoding, call routing, quality of service (QoS), authorization, authentication and accounting functions, and switching control to and from gateways are performed by a softswitch or a session border controller (SBC).
There is no physical limit to the number of calls that could enter or exit the network at any given time, as SIP trunking allows a customer to oversubscribe the number of voice calls.

The value proposition of SIP trunking lies not so much in the cost benefits, but in the applications scalability offered by IP networks in general.
