What is VoIP?

Voice over Internet Protocol – or VoIP – is the term for the technology that sends telephone and video calls over the Internet, as opposed to traditional phone lines. Dynamic uses market-leading software from 3CX to offer advanced VoIP systems, delivered as on-site or hosted solutions.

Our VoIP systems are secure, flexible and scalable - serving organisations of 5 or 5000 users equally well. And our VoIP systems provide both telephone, chat and video conference functionality as standard.

Future proof telephony 

In 2025, BT will turn off all ISDN and PTSN phone lines. This planned change to technology will make traditional phone systems obselete. All companes will, therefore, need to have transitioned to a VoIP solution by this time. 

If your phone system is nearly at capacity now, you'll want to act quickly! In preparation for a 2025 shut off, BT will stop selling new lines in 2020. This will make the expansion of existing phone systems impossible. Companies will be stuck with their current phone capacity. Migrating to VoIP telephones will now make your phone setup future proof.

Cost savings

By removing fixed telephone lines and replacing them with cheaper SIP trunks, and significantly reducing call costs (compared to traditional telecoms), moving to VoIP telephones, you can expect to save as much as 40% over your existing telecoms solution.
You may be concerned about the outlay for replacing phone hardware, well you don't need to be!. Our VoIP software has the option to allow you to access your telephone system and make calls from your PC with a headset or via your mobile phone with the 3CX app. This can effectively remove the need for a desk phone altogether.

Flexibility and functionality

With the ability to access your VoIP telephone system from a desk phone, your PC or your mobile phone or device, you need never miss a call again. Easy routing means you can take calls when out-of-the-office that appear as if you’re there. This makes our VoIP solution perfect for external working.
If there are times when you are unavailable, users have access to advanced voicemail functionality, with the option for messages to be automatically emailed to them. Alternatively, calls to your phone can be routed to any other phone on your system with ease.


Our VoIP telephone systems are also set to work with popular IP phones, VoIP gateways and SIP trunks out-of-the-box. Should you need assistance adding new desk phones to your system, it’s all part of the service - we can set them up at our office and courier them to you. Once received, just plug in a network cable and you’re ready to go. By doing this, you can give your regional offices or remote workers access to your central phone system. You’ll then get free-of-charge calls to these phones and any others on your network.
