FAQ
Frequently asked questions
Do I have to change my phone number?
Yes — and it is simpler than it sounds. You get a new professional number active in minutes, while your old line keeps working in parallel. You announce the new number at your own pace (email signature, website, Google Business) and cancel the old line only when you are ready.
Can I keep my old line during the transition?
Of course. Nothing is cut off: your current line stays with your current provider until you decide to cancel it. Many customers run both in parallel for a few weeks and even set up a forwarding message on the old number.
What happens to my current extensions?
Extensions can be recreated and configured within Nexen. During onboarding, our team helps you map the full extension structure of your current PBX.
Is there a service interruption?
No. There is no migration to fail: your new number is activated instantly on our infrastructure, and your old line keeps working until you cancel it. Zero-risk transition.
