A VoIP (or voice over ip) phone is a device that uses Voice Over Internet Protocol (VoIP) technology to receive and make phone calls over an Internet connection. It converts voice signals into digital packets for transmission and translates digital signals from the internet into standard audio.
VoIp business phones provide an affordable solution for managing calls in companies of all sizes from UK small businesses to call centres, or large corporate organisations. Modern Business systems allow for additional business applications such as unified communication, allowing calls, texts, emails, and chats over the Internet. Phone systems for businesses can integrate with other business software, offering flexibility and versatility with many business uses. With the announced fade out of traditional systems at the end of 2025, many phone models will become obsolete and you will need ip phones.
Choosing cloud phone systems with voip allows an up to date solution for your business. A hosted voip phone system will allow you to make and receive phone calls using an internet cloud based service, without interruption as your business grows.
Benefits of Our VoIP System
Made for Business
Businesses will need to prepare by searching for a system using the latest voip technology as regular phones are phased out, and the great news is that VoIP systems provide many business phone features, and IP telephony along with tools like caller ID, video calls, SMS and features such as call forwarding, and most importantly with excellent voice quality, meaning that your office phones are no longer necessary and your number can now travel with you simply wherever you need to work.
Advanced Features
VoIP networks offer advanced call management features like call forwarding, voicemail, caller ID, and call waiting. Modern systems help businesses stay organised and improve customer service, whilst reducing your phone service costs. Traditional phone lines may have similar features, but they are often more expensive and require more equipment and setup compared to VoIP.
Quality of Calls
Voice over Internet Protocol (VoIP) offers good call quality, but it depends on your internet connection. A strong connection ensures clear and consistent audio, while a weak one can cause interruptions and poor sound.

Technical Requirements for Cloud VoIP Phone Systems
Businesses need the right equipment and services to make VoIP calls work.
Hardware
VoIP requires minimal hardware compared to a traditional pbx system. You’ll need a modem and router to connect devices to the internet. A modem links to your ISP, while a router connects multiple devices within a network.
Optional equipment includes a VoIP gateway, which converts analogue signals to VoIP and supports communication with traditional phone systems. You can also use VoIP desktop phones for familiarity or headsets for hands-free calls. However, a modem and router are the only essentials for basic VoIP functionality.
Internet Connection
An internet connection is often considered the only requirement for VoIP calls, but a slow connection can lead to poor call quality and reliability issues. To ensure clear and stable calls, you’ll need a fast and consistent internet connection.
A single VoIP line requires at least 100Kbps. It’s a good idea to add 15% to your bandwidth calculations to account for network traffic and fluctuations. Upgrade your internet connection when usage reaches 80% of your total bandwidth. Pushing your connection to its limit can cause performance problems.
Bandwidth
Internet speed is essential for good VoIP call quality, but speed alone isn’t enough for the best performance. VoIP requires an internet connection speed of 90 kbps to 156 kbps.
Phones need a stable, dedicated amount of bandwidth for clear calls and reliable faxing. Even a single computer on a high-speed connection can use up bandwidth, depending on its activity. This can lead to dropped calls, choppy audio, failed faxes, and other communication issues.
Software
Businesses will need compatible software like a VoIP softphone or mobile app for each employee, in addition to the necessary hardware and internet connection. Softphones work well with hosted VoIP systems and can be installed on computers, tablets, or smartphones.
For those using desk phones, purchasing extra software licenses might be required for features like phone call recording or conferencing. The cloud system software must also be set up to fit the business’s needs. This includes creating user accounts, setting up extensions, assigning call routes, and enabling other essential features to ensure smooth communication.
Adding intrusion detection systems and firewalls can strengthen security and protect the VoIP system from unauthorised access or potential threats.

Frequently Asked Questions
Have a question in your mind?
Can I set up my own VoIP system?

What phones can be used for VoIP?
VoIP works with many types of phones. You can use IP phones, which are specifically designed for internet calling. Traditional phones can also be used if connected to an adapter.

Cloud-based phone systems also offer flexibility and compatibility with all these options, making them a great choice for small businesses. Choose the option that fits your needs and budget.
Are VoIP phone systems cost-efficient?
Businesses choose VoIP mainly for the cost savings it offers. Unlike landlines, it uses your existing internet connection instead of a separate system. VoIP also offers advanced technology for voice calls over the Internet, which improves business communication. Additional features like call forwarding and caller ID, which are often extra with traditional phone systems, come standard with most VoIP services, making it a cost-effective and efficient solution.
