Voice SIP Trunking

What is SIP Trunking?

SIP trunking is a method of delivering telephone and other unified communications services over the internet. It works with a SIP-enabled PBX (private branch exchange). SIP stands for Session Initiation Protocol — the communications protocol for signaling and controlling multimedia communication sessions. SIP trunking replaces traditional telephone lines or PRIs (Primary Rate Interface).

Before SIP, voice calls were carried over the Public Switched Telephone Network (PSTN) — the copper phone lines we traditionally associate with the telephone. SIP trunks are virtual phone lines that allow you to make and receive phone calls over the internet to anyone in the world with a phone number, whether they are using VoIP or the PSTN.

Key Features of SIP Trunking

  • Quality of Service (QoS) — Ensures audio quality remains excellent even during high-bandwidth activities like video streaming or large file downloads.
  • Cost Control — SIP calls go through the Internet, significantly reducing costs for both local and international calls.
  • Dynamically Adaptable — Greatly simplifies business communications across multiple locations, assuring maximum availability and business continuity.
  • Excellent Call Quality — With the right solution and proper router configuration, SIP calls are indistinguishable from calls made over traditional telephone lines.
  • Easy Implementation — Shring provides easy setup instructions and a user-friendly online control panel for day-to-day management.
  • Converged Infrastructure — Brings voice and data communications together into a single, unified network, reducing costs and enabling a more scalable communication platform.

SIP vs VoIP

Although SIP and VoIP are sometimes used interchangeably, they are not the same thing. VoIP is a broad term covering any phone calls made over the Internet. SIP is one specific protocol that enables VoIP.

The Benefits For You

The primary benefit is lower communications cost. Whether you choose an unlimited SIP trunk that includes most local and long-distance calls to the US and Canada, or a plan with a bundle of minutes, you will save money versus the traditional approach. Our solution is flexible — purchase only what you need now and easily grow or scale back at any time.
