Introduction & History
Voice over Internet Protocol (VoIP) is a technology that enables businesses to make and receive phone calls using an internet connection instead of a traditional phone line. VoIP for business converts your voice into digital data, sends it online, and delivers clear, reliable audio on the other end.
VoIP was launched in 1995 and become widely known when Skype launched in 2003, offering PC to PC calls. Over the years VoIP has become more popular because it is easy to scale, offers advanced features like voicemail-to-email, call recording, auto-attendants, video calls, and CRM integration. VoIP also supports remote and hybrid working, enabling employees to take calls from desk phones, computers, or mobiles.
VoIP is a generic name for the service, not the brand or product.

Benefits of VoIP for Business
There are several built in benefits to VoIP which leave traditional phone lines way behind. Plus, with the 2027 PSTN shutdown (read about that HERE) all business will need to migrate to VoIP.
Lower and Predictable Costs
Traditional phone systems come with line rental, hardware charges and high call costs. VoIP removes most of these expenses. Complete Voice & Data offer tailored VoIP packages, so you only pay for the features and users that you need.
Work from Anywhere
With VoIP for business, your team can make and receive calls from the office, home or on the move. Plus, they are not restricted to a traditional fixed line phone, they can use a mobile app, desktop softphone (one that connects directly to the internet) or their laptop or PC. Complete Voice & Data will ensure your staff stay connected wherever they work.
Advanced Features as Standard
VoIP for business gives you powerful features which you won’t find on a fixed line phone (or you may be charged extra). These include:
- Call menus – to route enquiries accordingly.
- Call recording – for compliance and training.
- Voicemail to email – save time and increase efficiency.
- Hunt groups – make sure you never miss an enquiry.
- CRM integration – to measure call stats.
Built-In Business Continuity
If your office loses power or internet access, your calls can automatically forward to mobiles or alternate sites. Complete Voice & Data builds resilient VoIP systems so your customers can always reach you.
