FAQ

VoIP Questions Answered

What is VoIP and how does it work?

VoIP (Voice over Internet Protocol) lets you make phone calls over the internet instead of a traditional phone line. Calls are compressed into digital packets, sent over your broadband, and converted back to audio at the other end — delivering high-quality, cost-effective calls from any device.

Can I keep my existing phone number?

Yes. KomTek supports number porting, so you can transfer your existing geographic or 03-prefix number to our platform at no extra charge. The process typically takes 5–10 working days.

What equipment do I need?

You need a broadband internet connection and either a compatible desk phone (Grandstream, Cisco, Yealink, or Snom) or our free Komtek Communicator softphone app on any smartphone, tablet, or PC. We can supply and configure hardware if needed.

What is the uptime guarantee?

KomTek guarantees 99.999% uptime backed by UK-based data centre redundancy and multi-node network architecture — that's less than 6 minutes of potential downtime per year.

Is there a free trial available?

Yes. KomTek offers a free trial for up to 5 users with 2 desktop phones and 50 minutes of domestic calls per user per month. Trial hardware must be returned within 21 days if you choose not to continue. Contact us to get started.
