Gregg SIP Trunking
SIP Trunking is an Internet Engineering Task Force (IETF) standard protocol for initiating an interactive user session that involves multimedia elements such as video, voice, and chat.
Many PBX platforms are based upon the evolving SIP (Session Initiation Protocol) standards, which provide a powerful platform to deploy, manage and use SIP based IP phones and other third party SIP devices, such as conference room accessories, paging equipment, application servers, video phones and video conference servers.
SIP Trunking
A SIP trunk is a service offered by an ITSP (Internet Telephony Service Provider) that connects a company’s PBX to the ordinary public switched telephone network (PSTN) via the Internet using the SIP Voice-over-IP (VoIP) standard.
Many enterprises want to make full use of their installed IP PBXs and not restrict themselves to communicating over IP only within the enterprise. A SIP trunk provided by an Internet Telephony Service Provider (ITSP) connecting the enterprise to the traditional PSTN network is the solution.
Unlike traditional telephony (POTS lines, T-1 circuits, PRI circuits, etc.), where bundles of physical wires were once delivered from the service provider’s central office to a business, a SIP trunk allows a company to replace these traditional fixed PSTN lines with PSTN connectivity via a SIP trunking service provider over the Internet.
