VoIP FAQs

Common questions about business VoIP

Moving to VoIP is straightforward when it is planned properly. Here are some of the common questions businesses ask before switching.

We’ll help you understand the best setup for your users, numbers, broadband and day-to-day calling needs.

What is a VoIP system and how does it work?

VoIP stands for Voice over Internet Protocol. It allows you to make and receive phone calls over your internet connection instead of using traditional phone lines. Your voice is converted into digital signals and delivered like a normal phone call.

What are the benefits of using VoIP?

VoIP can reduce call costs, improve flexibility and provide useful features such as call routing, voicemail, call recording, mobile apps and remote working support.

Is VoIP reliable?

Yes, VoIP is reliable when used with a stable internet connection. We can also advise on broadband, failover and call forwarding options to help maintain continuity.

Can I keep my existing phone number?

Yes, in most cases your existing phone number can be ported to the VoIP service, helping you move across with minimal disruption.

Can I use VoIP on my mobile or laptop?

Yes, VoIP can work through desk phones, mobile apps and softphone software on laptops or desktops, giving your team more flexibility.

Will VoIP work with my current broadband?

VoIP can work with most broadband connections, but call quality depends on the speed, stability and reliability of the connection. We can review this before setup.

How long does VoIP setup take?

Setup time depends on the number of users, handsets and number porting requirements, but most straightforward installations can be planned and completed quickly.

What happens if the internet goes down?

If your internet connection fails, calls can often be redirected to mobiles or backup numbers so your business can continue receiving important calls.
