Session Initiation Protocol (SIP) is how your organization can support voice over IP (VoIP) calling. It’s a protocol for real-time audio sessions between two endpoints (phones). Those sessions could be one-to-one calls or one-to-many conference calling. SIP trunking is the technology behind connecting IP based communications infrastructure to the Public Switched Telephone Network (PSTN).
A SIP trunk solution is the best way to connect your organization's IP-PBX and the PSTN. It feels just like an analog phone line, but uses a SIP connection provisioned from a SIP trunk provider. SIP trunking is virtual, not physical. That makes SIP trunking significantly less expensive than traditional PBX phone systems — and much easier to scale.
