What Is SIP Trunking? How It Works, Benefits, & How To ...

What Is SIP Trunking?

SIP (Session Initiation Protocol) trunking is a modern technology that enables voice and multimedia communications over an internet protocol (IP) network instead of traditional phone lines. It uses SIP, an application-layer protocol, to establish, modify, and terminate communication sessions between two or more endpoints.

The term “trunking” refers to the consolidation of multiple communication channels or lines into a single, logical connection or “trunk.” SIP trunks provision Voice over Internet Protocol (VoIP) connectivity between an on-premise phone system and the public switched telephone network, also known as PSTN. 

For instance, an office might have an existing PBX for phone service. SIP trunks provide phone service for the entire office so they can reach the outside world.

Running your small business phone system through SIP trunking is affordable, but it’s not necessarily for everyone. It replaces the need for physical lines. It also lets you easily add new phone lines or modify your phone service without disruptions or the need to buy new hardware.

If you’re still unsure about SIP trunking, Tom from Nextiva gives a great explanation in this 2-minute video:

SIP trunking can revolutionize your business by letting you upgrade your PBX to an internet-powered phone system.

It operates similarly to HTTP, which is the very basis of browsing web pages on the internet. SIP was embraced by the open-source community and acted as a catalyst for business phone service. Also, SIP’s capabilities extend beyond phone service into broader messaging functions.

How Does SIP Trunking Work?

SIP trunking works as an intermediary between your business phone system and the Internet Telephony Service Provider (ITSP). See the diagram below showing how calls flow from a SIP phone (VoIP) in a business to the outside world — it’s fascinating!

SIP trunking replaces traditional phone lines with a virtual connection, allowing your business to make and receive calls using your existing internet connection. It acts as an intermediary between your on-premise phone system (PBX) and the Internet Telephony Service Provider (ITSP) that delivers your service.

Think of it this way: traditionally, businesses relied on physical phone lines to connect calls. SIP trunking bypasses these lines by converting voice calls into digital data packets that travel over your internet network. This eliminates the need for expensive installations and clunky hardware.

Transitioning to SIP trunking

Here’s what you’ll typically need to make the switch to SIP trunking:

• Reliable Internet Connection: Since calls travel over your internet, a stable and high-speed connection is crucial for clear call quality.
• SIP-compatible PBX System: Your PBX acts as the brain of your phone system. Ensure it’s compatible with SIP technology, or you may need an upgrade. Some providers offer hosted PBX solutions, eliminating the need for on-premise hardware.
• VoIP Phones or Adapters: For making and receiving calls, you’ll need phones that work with SIP technology (VoIP phones). Alternatively, if you prefer to keep your existing phones, SIP adapters can convert them for use with VoIP calls.
• Network Connection for Phones: While voice calls travel over the internet, your phones themselves might still require a separate network connection for features like internal calls and intercom functionality.

Direct inward dialing (DID) numbers: Enhancing flexibility

DID numbers are an additional feature you can leverage with SIP trunking. They provide a cost-effective way to assign specific phone numbers to employees or departments within your company.

SIP trunking connects existing communications hardware to the telephone network.

Here’s how it works:

• Your ITSP assigns you multiple phone numbers, each linked to a specific SIP extension within your PBX system.
• Incoming calls with a specific DID number automatically route to the designated extension, eliminating the need for a receptionist or auto-attendant.
• The beauty of SIP trunking with DID is the elimination of separate phone lines for each number. You only pay for the service itself, reducing infrastructure costs.

Using DID numbers with SIP trunking, you can enhance call management for various departments like customer service, sales, or even individual employees, improving overall communication efficiency.

What Is SIP Trunking Used For?

The main role of SIP trunking is to replace PRI technology. PRI, or Primary Rate Interface, has been used for decades to deliver lines of voice and data using physical copper lines.

Essentially, it’s a bundle of analog phone lines put together. PRI can be costly to maintain since the hardware is becoming outdated rather quickly.

With SIP trunking, this happens using VoIP technology. SIP also supports other data like instant messages and video conferencing.

SIP trunking is the right choice for anyone ready to move their business communication on a light budget.

This warrants a follow-up question: how will you know that your company is ready for SIP?
Here are some questions to consider:

• Are you currently paying for call capacity that you don’t need?
• Is it expensive to maintain all your equipment?
• Do your voice calls drop unexpectedly or need higher reliability overall?
• Do you have remote employees and/or employees that travel or relocate often?

In short, SIP trunking is used for call setup, management, and teardown. It’s flexible, reliable, and quite lightweight. This means you can focus on your business instead of the technicalities. SIP is the basis for VoIP communications, and SIP Trunking is used to provide VoIP connectivity through a PBX.

These standards, prescribed by organizations such as the Federal Communications Commission (FCC) in the United States, ensure that providers maintain a high level of network integrity and reliability.

Moreover, providers are often required to comply with international standards such as ISO/IEC 27001, which provides specifications for an information security management system (ISMS). This global benchmark requires providers to systematically manage their sensitive information, applying rigorous risk management processes to ensure data security.

For businesses, partnering with a SIP termination provider that demonstrates compliance with these critical standards not only mitigates risk but also instills confidence in the resilience of their communication systems.
