SIP Trunking

SIP Trunking

SIP, or Session Initiation Protocol, is the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network. A SIP trunk replaces the need for traditional analog or T1-based Public Switched Telephone Network (PSTN) connections with termination instead provided over a company’s public or private Internet connection through a SIP provider. While some companies may already enjoy the benefit of VoIP systems within their PBX across their Local Area Network (LAN) to connect to IP phones, SIP Trunking takes advantage of shared lines such as a company's Internet connection to allow more flexibility in communications.
