Your UC Provider Is Winding Down? A Singapore Guide

A Forced Move Is Different From a Planned One

Most businesses switch phone systems when they choose to. A provider ending or reducing a service changes the situation: there is now an end date you didn't pick, and everything has to be in place before it arrives. Dromlik, a cloud phone system for Singapore businesses, helps teams in exactly this position move across without dropping calls, and the sequence below applies whichever provider you end up with.

Step 1: Get the Facts in Writing

Before you plan anything, ask your current provider to confirm the following in writing. Don't rely on a phone call or on something you've heard secondhand.

The exact date service ends, and whether it ends for all features or only some
Whether they will support number porting to another provider, and what they need from you to start it
How long they will keep call logs, recordings, voicemail, and contacts available for export
What happens to prepaid fees and your contract term, including any notice period

Your contract will set out your rights here, so check it, or ask a lawyer if the terms are unclear. The key point is that your numbers are the one asset you can't easily replace, so everything else is planned around getting them moved before service stops.

Step 2: Protect Your Numbers First

Numbers can only be ported while the current provider still holds them and is still operating, so porting should start early, not at the deadline. Don't let the account lapse or terminate before the port completes.

List every number you use: main lines, direct dials, department numbers, fax, and any numbers on printed materials or Google Business listings
Gather the account details your new provider will ask for to submit the port
Ask for the port to be done in planned batches, rather than all at once, if you have many numbers

Dromlik offers free number porting from your current provider, and Singapore numbers (+65) are S$12 per number per month. Our guide to local numbers and porting covers what to check.

Step 3: Export What You Need Before It Disappears

When a provider winds down, the data stored in their platform can be removed on a short timeline. Export what matters while you still can:

Call recordings, if you keep them for compliance or quality. These can contain personal data, so store exports securely. See our guide to call recording and compliance.
Call logs and reports, for any period you need for billing or review
Contacts and speed dials, including shared directories
Voicemail greetings, IVR prompts, and hold music, so you can reuse the recordings
Call flow documentation: your IVR menus, ring groups, time rules, and holiday schedules, written down or screenshotted

Call flows are the part people most often forget. If nobody has documented them, take the time to map them now, because rebuilding from memory is where errors creep in.

Step 4: Rebuild and Test in Parallel

Set up the new system fully before any number moves. Create users and extensions, rebuild routing and departments, connect any CRM or helpdesk integrations, and set up desk phones or apps. Then test inbound and outbound calls, after-hours behaviour, and transfers. For larger teams, our guide to migrating 100+ users covers staged rollout, and multi-department routing covers rebuilding department structures.

Step 5: Cut Over and Watch Closely

Once ports complete, your numbers ring on the new system. Keep a short list of test calls to run straight away, and have a named person on your side watching the first few days for anything unexpected. Tell staff what has changed and where to get help.

A Realistic Timeline

When	What to do
As soon as you hear	Get the end date and port terms in writing, list all numbers
Weeks 1-2	Choose a new provider, start the port request, begin exporting data
Weeks 2-4	Build and test the new system in parallel, train staff
Cutover	Complete ports in batches, run test calls, monitor closely
Before the end date	Confirm everything works, then close out the old account

Porting times vary, so treat these as a planning guide rather than a promise. The earlier you start, the more room you have if something takes longer than expected.

What to Look For in the New Provider

Genuine local Singapore numbers and free, managed porting
Hosting that keeps your call infrastructure in Singapore
Support for the features your team actually uses today, such as routing, recording, and integrations
A clear migration process and a named contact, not just a ticket queue
Plans that cover your needs, from core business calling to a full contact centre. See our post on UCaaS vs CCaaS if you're unsure which you need

Common Questions

Can I keep my existing business numbers?

In most cases yes, through number porting, provided the port starts while your current provider is still operating and holds the numbers. Start early and confirm the process in writing.

How long does a migration take?

It depends on team size and the number of lines. Small teams can move within a few business days, while larger organisations are better off planning several weeks with staged ports.

What if I can't get my old data out?

Ask the provider what export options exist as soon as possible, and prioritise call flow documentation and any recordings you're required to keep. Contact lists and greetings can usually be rebuilt.

Will there be downtime?

A properly planned port, with the new system built and tested first, should involve minimal to no downtime. The risk rises when everything is left to the final days.
