SIP Trunking

A SIP trunk is a virtual phone line that uses the Session Initiation Protocol (SIP) to deliver voice and other unified communications services over the internet. It replaces traditional telephone lines or PRIs, allowing businesses to make and receive calls using their existing internet connection.

SIP and VoIP

VoIP (Voice over Internet Protocol) is the technology that transmits voice calls over the internet. SIP trunking is the method used to connect VoIP-enabled phone systems to the public telephone network. Think of VoIP as the voice service, and SIP trunking as the connection that makes it accessible to the outside world.

Choosing the Right SIP Trunk Provider

The right provider should offer reliability, easy setup, flexible pricing, and strong support. Look for features like Tier-1 networks, contract-free terms, simple provisioning tools, and responsive technical assistance—especially if you're building a recurring revenue stream as a reseller.
