Changing country often means changing telephone arrangements as well. A UK VoIP number offers another option: keep a UK contact number and have the calls delivered over SIP to a compatible device wherever you are living.
Keep a UK telephone contact point
With SIP, the telephone number and the physical location of the handset are largely separated. A UK number can be hosted by UKDDI while the device receiving the call is connected to the internet in another country.
That means you can retain a familiar UK contact number even when you are no longer physically based in Britain.
Make calling simpler for family members
A UK number can be particularly useful for relatives who prefer conventional telephone calling. They do not need a messaging app, a video service or an international dialling code; they call the UK number and your registered VoIP phone rings.
The caller's own provider remains responsible for the cost of the UK call.
Avoid publishing your overseas mobile everywhere
A separate UK VoIP number can also help you avoid using your personal overseas mobile as the contact number for every business, club, organisation or customer.
The UK number becomes a consistent contact point while your personal mobile number can remain private.
Use a real telephone instead of relying on an app
VoIP does not have to mean sitting in front of a computer with a headset. A dedicated SIP desk or cordless telephone can remain registered to the service and ring like an ordinary phone.
That can be more convenient in a permanent overseas home than relying on a laptop application being open whenever somebody calls.
Make calls back to Britain through your SIP service
Your SIP account can also support outbound calling when configured for it. Calls are then sent through the UKDDI service rather than being placed directly through an overseas mobile provider.
Call charges, destination restrictions, caller-ID rules and package allowances depend on the UKDDI service selected.
What if I move again?
Because the service uses an internet connection, moving does not necessarily mean changing the UK telephone number. Take the compatible phone with you or configure another authorised endpoint and register it to the service.
For expats, that makes a UK VoIP number a simple and portable connection back to the UK.
Choose your UK number and how you want to answer it
Search UKDDI number availability, then choose SIP trunk or hosted SIP-phone delivery. If you need a physical handset, compatible VoIP hardware can be added separately or alongside the service.
Service availability can depend on the local internet connection, firewall or router, local telecommunications rules and the UKDDI service configuration. Emergency calling should be handled according to the arrangements applicable where you are physically located.
