Session Initiation Protocol (SIP Trunking)
A SIP trunk is a direct connection between your organization and service provider. SIP solutions work with preexisting PBX equipment and VoIP phone systems . Most solutions will instantly deploy in the cloud.
In addition to VoIP calls, SIP trunks can also carry instant messages, multimedia conferences, user presence information, Enhanced 9-1-1 (E9-1-1) emergency calls and other SIP-based, real-time communications services.
SIP, the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network, is the basis of SIP Trunking. SIP configurations are popular because they are easy to design, operate, maintain, upgrade and scale. Plus, SIP trunking can provide immediate savings and substantial return on investment to most organizations.
