The number one worry when moving phones to the cloud is "will I lose my number?" You won't. Number porting in Malaysia — and the simpler bring-your-own-trunk option — both let you keep the numbers customers already call. Here's how each works and how to avoid downtime.
Two ways to keep your number
- Bring your own trunk (BYOC) — point your existing line or TM MLS trunk at the new cloud phone system. No port needed; same numbers, new system behind them. Fastest, lowest-friction.
- Port the number — move the number itself to the new provider's carrier. Useful when consolidating carriers or getting new capabilities.
How porting works
You request the port with the new provider, supply proof of ownership (a recent bill and account details), and the carriers coordinate the transfer. The number keeps working on the old service until the agreed cut-over, so there's no gap if it's planned properly.
Avoiding downtime
- Build and test first — recreate your call flows on the new system before cut-over.
- Keep the old line live until the port completes.
- Cut over off-peak — often after hours — with a fallback ready.
Which should you choose?
If your current trunk contract is fine, BYOC is usually the simplest path. If you're consolidating or want new numbers, port. A managed provider handles either — see our migration guide and the Managed PBX package.
