SIP Trunking: 8 Things You Should Know

SIP Trunking: 8 Things You Should Know

You may have heard of SIP trunking. You may not. Either way, we’re sure we can teach you some valuable things about SIP technology.

SIP trunking is a communications technology. Specifically, SIP trunks connect businesses to the Public Switched Telephone Network (PSTN) via the internet.

Many businesses have a phone line, an internet connection and a phone system. SIP trunking allows you to eliminate your phone line, thereby simplifying your communications systems and reducing your costs. Clever stuff, right?

Here are 8 things we think every business owner should know about SIP trunking.


SIP is Popular

Today, many businesses are opting to ditch their phone line and go with SIP. Globally, the SIP trunking market is expected to reach $9 billion (£6.9 billion) by 2021. In fact, in 2018 42 percent of companies send 100 percent of their traffic over SIP trunks. Businesses across the world over are moving towards internet voice communications due to its improved reliability, centralised applications and flexibility.


SIP Saves Businesses Lots of Money

Put simply, IP connections are cheaper than ISDN lines in terms of rental costs. These savings are passed on to the customer, with the average business saving up to 90 percent on international calls and 40 percent on local calls. To put that into perspective, that’s a saving of around £895 per month for a business with 30 phones.


SIP Enables Unified Communications

Modern communications don’t have to be complicated. With SIP trunks, it’s possible to combine email, instant messaging, video conferencing and voice communications into a single solution. Equipped with unified communications, businesses no longer have to deal with multiple providers and benefit from consistent processes across multiple locations.


SIP Is Inherently Scalable

Unlike traditional phone systems, it’s incredibly easy to scale the number of SIP trunks up and down. This means that, if your business grows quickly or unexpectedly, or if you need to add or remove lines to accommodate seasonal call influxes, you can do so instantly. A SIP solution will grow with your business, meaning you never pay for unused lines or struggle with too many calls.


SIP Is Highly Reliable

Previously, SIP had a reputation for being unreliable. Because SIP was first designed in 1996, the public internet it used was a lot more unreliable than it is today. In 2018, the public internet is incredibly reliable and this means that SIP delivers high-quality calls and communications consistently.


SIP Trunks Make Multi-Site Communications Easier

For businesses which operate over multiple sites, SIP will eliminate the need to have separate PBX systems. Using SIP across multiple locations, businesses can reduce the number of connections as well as maintenance costs. By rationalising multi-site connections in this way, businesses will simplify system management and implement consistent communications processes.


SIP Maximises Bandwidth Utilisation

Most businesses already pay for a high-quality internet connection. By opting to use SIP trunks, you will get more value from your internet service since you will be using one connection to support multiple services. Most high-quality internet connections can support a SIP solution without compromising connection quality.


SIP Reduces Hardware Costs

SIP eliminates the needs for underlying hardware such as expensive PBX systems and call lines. This hardware costs a lot to purchase initially and requires ongoing maintenance. By removing the need to purchase this hardware, your business will save money on initial costs as well as ongoing maintenance costs.
