What is VoIP?

VoIP (Voice over Internet Protocol), also referred to as IP telephony, is the technology used for the delivery of communications (voice, voice messaging, SMS, fax) over IP (Internet Protocol) networks. 

Plainly speaking, VoIP is the technology used for people to communicate over the phone via the Internet. One´s voice signals are converted to digital signals, which then travel over the internet to reach the person one is calling over the phone. As the exchange is done online, you won´t need a cable wire as you would with PSTN.

As VoIP doesn’t use dedicated phone lines, the cost of phone calls is lower than with PSTN, making the transfer to VoIP a popular cost-saving move for businesses.

What is SIP?

SIP stands for Session Initiation Protocol. It is the protocol used for controlling and signalling communications done over the Internet, which covers most multimedia communications such as voice calls, video calls, instant messaging, as well as in private IP telephone systems. 

Basically, SIP is the direct connection from one device to another that utilizes VoIP to communicate. Computers and mobile devices connected to the internet, including phones communicating over LTE use SIP. 

Why switch to VoIP and SIP?

The switch to all-digital telephony isn’t just for the sake of abandoning your phone system because it’s old. Moving to VoIP and SIP will bring your business to the future with the benefits that all-digital communications have to offer.

Fixed and Reduced costs

As your voice and video calls are done via the Internet, the cost remains fixed regardless of distance. With the need for expensive line rental removed, reduction in the cost of communications may be up to 70% or even more. 

Advanced Features

With VoIP and SIP, you can use the same number on any device to make and take calls from any location. This flexibility from a cloud-based system also allows you to work from, or even move to, anywhere in the UK and retain the same business numbers. 

Collaboration with customers and colleagues becomes more efficient as this system will allow you to link business applications for seamless voice calls or video chat experiences.

Aside from being more flexible, your communications network is also more resilient. With multiple Internet connections, backup happens automatically. Even with a major site failure, you may still be able to use your business phone at other locations such as the Internet connection at your home. 

If your business already has an existing Internet connection, installation is quick as there will be no need for additional line installation.

ISDN Switch off

In 2015 BT announced they will be switching off their PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network) networks by 2025. 

Dismantling and phasing out of these systems as well as the migration to IP networks is well underway. In fact, ISDN services are not available to order anymore with the gradual phasing out of these legacy systems. 

This impending switch-off will have a significant impact on your business if you are currently using PSTN and/or ISDN lines. With 2025 fast approaching, many businesses are migrating their systems over to more advanced, cost-effective, and flexible IP networks.

In the ever-changing world of technology, this change is a natural part of the evolution of phone systems for businesses.

With lower costs and advanced features, it makes perfect business sense to go digital as soon as you can. Don’t wait until the last moment to make the switch.
