SIP TRUNKS – VOICE CALLS OVER THE INTERNET

SIP Trunking is a robust communication technology that allows Phone Systems to work through the Internet, enabling companies to save time, reduce costs and provide advanced features. SIP stands for Session Initiation Protocol. SIP Trunks are being widely adopted because the old copper network is getting decommissioned and the NBN is coming through. This document is made to help you with any questions you have and give you an understanding of SIP and how it will benefit you. If you have any more questions, feel free to call Squareone.

What is SIP trunking?

SIP trunks are a replacement for the traditional phone line connectivity. This is the newest and most advanced technology in the telecommunications industry that allows calls to be made and received over the internet, enabling companies to have cheaper and more flexibility in terms of access via multiple devices. In addition to voice calls, it also supports video and messaging communication.

FAQs

A SIP (Session Initiation Protocol) trunk is a virtual version of an analog phone line. It uses the internet to deliver voice services and unified communications.

SIP trunks work by connecting your on-premises phone system to the Public Switched Telephone Network (PSTN) via the internet. It allows for the transmission of voice, video, and other multimedia communications.

Cost savings
Scalability
Flexibility
Improved reliability
Enhanced features (such as unified communications and advanced call routing)

A SIP-compatible PBX (Private Branch Exchange) or IP-PBX
An internet connection
A router and possibly a Session Border Controller (SBC)

This depends on the bandwidth of your internet connection and the codec used. Typically, one SIP trunk can support multiple simultaneous calls.

A PRI (Primary Rate Interface) line is a traditional, physical connection that uses T1/E1 lines to deliver voice services, whereas a SIP trunk is a virtual connection that uses the internet.

Purchase a SIP trunking service from a provider.
Configure your PBX or IP-PBX to connect to the SIP trunk.
Ensure your network is configured to prioritize voice traffic (QoS settings).

Quality of Service (QoS) is a set of technologies used to manage network traffic and ensure the performance of critical applications. For SIP trunking, QoS helps maintain high call quality by prioritizing voice traffic over less critical data.

SIP trunks can be secure if proper measures are taken, such as using encryption (TLS for signaling, SRTP for media), setting up firewalls, and implementing SBCs.

Costs vary widely based on the provider and the number of channels required. Pricing models may include per-minute charges, per-channel charges, or flat-rate pricing.

Yes, SIP trunking often reduces costs by lowering call charges, especially for long-distance and international calls, and reducing the need for physical phone lines.
