Business telecoms FAQ

Answers before you request a quote.

What is VoIP?

VoIP (Voice over IP) carries phone calls over your internet connection instead of traditional copper lines. It enables cloud PBX features, flexible routing and easier scaling.

Can I keep my number?

In most cases yes — UK geographic and many non-geographic numbers can be ported. We plan cutover windows to minimise disruption.

How fast is setup?

Simple deployments can go live quickly; multi-site or custom integrations take longer. We give realistic timelines after a short discovery call.

Do I need new phones?

Not always. Many customers use compatible desk phones, softphones or a mix. We confirm hardware and licensing with you upfront.

Can staff work remotely?

Yes — apps and softphones let people take and make calls as if they were in the office, with consistent numbers and routing.

What call packages are available?

We offer PAYG, UK unlimited and international add-ons, plus bespoke bundles for larger teams. Packages are matched to your usage profile.

Is VoIP reliable?

With a stable connection and correctly configured QoS, VoIP is widely used for business. We design redundancy and failover where uptime is critical.

Do you provide support?

Yes — our UK team helps with provisioning, changes and troubleshooting as part of your agreement.
