Cut costs and improve your service with a powerful on-premises phone system
Is your phone system holding you back? Our powerful on-premises systems can transform your business, while keeping costs low.
Every person in your firm can have their own direct dial number and voicemail inbox. And as your business grows, you can add handsets when new people join.
Our systems can be linked to your database so your customers’ names pop up when they call. And for better communications you can add instant messaging and conferencing.

- Changing to an IP phone system (including BT Cloud Voice)
- Moving premises
- Kitting out a new building or greenfield site (we’ll give you a quote based on plans and drawings)
- Planning an office refurbishment or reorganisation
- Struggling with bandwidth-hungry applications like video conferencing or data streaming and you need faster servers and PCs

FAQs
