​​VoIP is revolutionising the way we communicate, offering cost-effective, versatile, and feature-rich solutions for businesses.

PSTN FAQ'S
-
What is VoIP and how does it work?VoIP stands for Voice over Internet Protocol. It’s a set of technologies that enable users to make and receive phone calls over the internet. It allows businesses to ditch traditional landlines and replace them with a solution that can fit into a versatile workplace. An Internet Protocol (IP) address plays a big part in how computers and other devices communicate over the internet. When VoIP technology and IP addresses are used to make and receive calls, it gives us the ability to communicate over the phone wherever we can get internet access. This is different from what analog phone systems use to make and receive calls. Traditional phone services require specialised hardware called a Private Branch Exchange (PBX) to connect phone extensions to the Public Switched Telephone Network (PSTN). Instead of running through the copper wires that make up phone lines, VoIP just needs a high-speed internet connection to function.
-
How VoIP worksWhen you make a phone call through VoIP, the audio is sent over the internet as small data packets. Using real-time transport protocol, these data packets are routed through your VoIP service provider and delivered to the call recipient in less than a second. Because you are now leveraging the power of the internet, VoIP also comes with advanced features like call recording, voicemail, and call routing. This allows you to have full control over your telecommunications. It also makes your team function more efficiently with fewer communication mishaps.

How does Managed IT Support differ from break-fix IT services?Traditional IT support often operates on a break-fix model, where you only get help when something goes wrong. Managed IT Support, on the other hand, is proactive and continuous. It involves constant monitoring and maintenance to prevent issues before they disrupt your business.
-
Will Managed IT Support save my business money?Yes, Managed IT Support can be cost-effective. Instead of dealing with unexpected IT repair costs, you pay a fixed monthly fee for comprehensive support. This predictability helps with budgeting, and proactive maintenance reduces the likelihood of costly downtime.
-
Does Managed IT Support include cybersecurity services?Absolutely! A key component of Managed IT Support is protecting your business from cyber threats. This includes implementing firewalls, antivirus software, security patches, and monitoring for suspicious activities. Regular security audits and training for your staff are also part of the service.
-
Is Managed IT Support suitable for small businesses?Managed IT Support is beneficial for businesses of all sizes. Small businesses can particularly benefit as it gives them access to high-level IT expertise and support without the need to hire full-time IT staff. Larger businesses can also benefit by augmenting their in-house IT teams and ensuring 24/7 coverage.
-
What should I look for in a Managed IT Support provider?When choosing a Managed IT Support provider, consider their experience, the range of services they offer, their response times, and their ability to scale with your business. It’s also important to choose a provider that understands your industry and can offer tailored solutions.


What is PSTN & ISDN?
The PSTN (Public Switched Technology Network) is the traditional, copper wire-based telephone network which has remained largely unchanged since the early days of public telephone networks.
ISDN (Integrated Services Digital Network) is a digital platform that came into use in the 1980s to deliver not only voice, but video and other data too.
What is the PSTN & ISDN Switch Off?
We’re all familiar with the copper wire telephone network: in use since 1876, it’s kept business communications’ going for years. But that’s all about to change.
​
In 2027, the Public Switched Telephone Network (PSTN) is being switched off by BT Openreach, which means everyone, including businesses, currently using PSTN-based services will need to move to another service before then.
​
The alternative? Voice over Internet Protocol (VoIP), a solution that transmits voice calls and data using an internet connection.
​
This is a major step towards the United Kingdom’s mass IP-network migration, with VoIP core networks set to replace all the legacy PSTN services in just a few years’ time.
​
Embrace the future of telephony by replacing your landline with VoIP before the Public Switch Telephone Network (PSTN) is switched off in 2027.



What is replacing PSTN & ISDN?
From 2027, all consumers and businesses will make phone calls over broadband using VoIP systems. Voice over Internet Protocol (VoIP) allows voice communications over IP networks such as the internet. VoIP does not require a circuit-switched network. Instead, data is transmitted over a digital network. BT plans to switch to a system where all voice calls are internet-based and delivered via a fibre network, correlating with the upgrade of fibre networks across the UK, to support the shift to VoIP telephony.
​
VoIP calls can be made using a wide range of devices, including desktop computers, mobile phones, landlines and pretty much any other internet-ready device.
​
What is VoIP?
VoIP stands for Voice Over Internet Protocol and is often referred to as IP (internet) telephony or cloud-based telephony. In plain terms, VoIP systems make phone calls using the internet, rather than the traditional telephone exchange or landline network.
​
VoIP allows calls to be made on any device that has a reliable internet connection, including smartphones and laptops. A VoIP phone system is much more flexible, as they can be provisioned remotely, meaning you can add additional lines to the system easily. Call costs via VoIP are much cheaper when compared to traditional phone systems and usually come with innovative features.

Benefits of VoIP
VoIP is a much better alternative to traditional landlines, and it will be the industry standard for years to come. This technology offers many opportunities and benefits for your business:

Lower Costs
VoIP solutions are software-based, which means you don’t need any infrastructure, upfront costs, or additional hardware.

Additional Features
VoIP deskphones come with a wider range of phone features as standard, including video calling, Presence status, voicemails to email and easy-to-use call settings when needing to manage calls.

Scalable
As they are cloud-based, VoIP phone systems are easier to scale, meaning you can add additional handsets as your business grows. You’re only ever paying for what you need.

Increased Call Quality
As VoIP phone systems use your internet connection, the call quality on phone calls is much higher than systems still using an older network. The reliability of this connection is also much better.

Flexibility
VoIP solutions can be accessed from a variety of devices, which means you won’t be tied to a desk phone anymore and you’ll be able to take your calls wherever you are.

Future Proof
You’ll be protected against the ISDN switch off while helping make your business more efficient and saving money.
