A VoIP phone system provides your business with standard telephony features and functions but route your call traffic over the internet, resulting in lower call costs and monthly line rental.  

Cloud-based or ‘hosted’ systems also mean that you no longer have to worry about looking after on-site hardware.

Communicate and collaborate from anywhere on any device

A VoIP phone system empowers your team to collaborate and work from anywhere using features such as Chat, Video Calling, File Share, Voice Calling and Contact Centre features. 

Bringing the internet into your telephony solution provides versatility, allowing your employees to make and receive business calls from wherever they have an internet connection. With little to no hardware involved, VoIP phone systems are easily scalable to match your growth ambitions.

From our offices in Bristol and Cardiff we can help you choose the right VoIP phone system no matter where you are in the UK.

Info on Hold

The on-hold experience doesn’t just have to be cheesy music. Use hold and queuing time to relay useful service and sales information to your customers.

With Blackstar’s Info on Hold service, you provide the script. A voice over artist will record it over your choice of background music. Recordings are high-quality, adding an element of professionalism to your business. With various pricing structures, you can choose how often you change your messaging.

Providing relevant information to your callers can benefit your business in multiple ways. Service information improves the caller experience by reducing hold time. Providing sales and marketing information can turn time on hold into a potential revenue stream.


Not only can calls be made or received from anywhere, but VoIP systems also turn anywhere into a meeting room with out-of-the-box conferencing tools.

HD video and audio conferencing with no meeting or minutes restrictions are available as a standard feature. You can join or host meetings from wherever you’re connected. Apps for Android and iOS mean you can share content from your mobile.

Blackstar’s VoIP conferencing solutions include all of the standard host controls, like meeting lock, lobbies and participant permissions. Integration with Google and Outlook calendars makes scheduling easy. Pair it with a personal meeting room solution from Konftel or Poly to bring the conference room experience to the home office.

The cloud allows us to make and receive calls from anywhere. However, not all workspaces provide an ideal calling environment.

Pairing a headset with your cloud phone system allows you to be more flexible about where you take calls. A high-quality headset will provide noise cancellation, meaning fewer distractions and a better calling experience for your customers and your employees. 

Deployment features like Bluetooth or interchangeable USB/stereo connectors allow you to use the same headset with multiple devices.

Blackstar partners with Poly, Jabra and EPOS to provide you with the best choice for comfort, features and price when it comes to headsets


A wide range of handsets is available for Blackstar’s VoIP and Cloud solutions for people who like to pick up and dial a phone. Handsets are delivered to site pre-provisioned. Simply plug them into a working network port, and they’re ready to use.

VoIP handsets adhere to the work from anywhere ethos and are a great addition to a home office. All that’s required to use a handset at home is a network cable to connect to the router and a power adapter.

Blackstar works with Poly and Yealink. With a wide variety of models to choose from – including wireless DECT phones – there are plenty of options available to meet your business’s needs.
