01 · Assess your requirements
List your numbers, carrier contracts, staff, call flows and existing equipment. Check number-porting eligibility, connectivity and any fax, alarm or door-phone requirements.
PABX migration · Singapore
Replace your office PABX in Singapore.
Replace the cabinet with cloud calling. We assess number eligibility first, then scope the migration, supported devices and telco capacity.
Migration checklist
Know the full cost before you commit.
02 · Receive your full quotation
Review the proposed package, scope, setup, hardware, telco and call charges, applicable tax, payment schedule, annual commitment and any current-contract exit costs.
03 · Approve before setup
Accept the written quotation and agreed scope before paid service, installation or a number-porting order begins. An enquiry or plan recommendation does not commit you to a purchase.
04 · Build & test
Configure the agreed extensions, IVR, queues and integrations. Test incoming and outgoing calls, transfers and supported devices before moving your public number.
05 · Agree & complete cutover
Confirm the carrier-dependent change window, staff communications and fallback arrangements. Move eligible numbers only after readiness checks and your approval.
06 · Train & hand over
Complete administrator and user training, confirm support contacts and acceptance checks, then decommission old equipment when it is safe to do so.
Analog equipment
Assess fax, alarms and door phones separately.
Existing analog equipment is not automatically compatible with a cloud service. Some devices need a supported gateway; others need a separate service. Do not cancel those lines until the technical assessment is complete.
Your questions
Before you switch
Can I keep my business number?
Number portability depends on your carrier, line type and number. PSTN / ISDN and copper lines require a technical assessment. We confirm eligibility before agreeing a cutover.
Do we need new desk phones?
Supported IP phones or gateways may be reused after a compatibility check. Mobile, desktop and web clients are also available. Analog devices may need gateways.
What does the monthly price include?
The LinkusPBX phone-system package. Telco service, external calls, applicable tax, hardware, setup and third-party licences are scoped separately in your quotation. An annual commitment applies.
Can I request a product demo?
Ask for a product demo using the enquiry form or sales chat. Our team will confirm availability, timing, the features to demonstrate and any setup requirements. A demo request does not start a paid subscription.
What happens if the internet fails?
Cloud calling depends on connectivity, devices, power and telco service. We assess backup connectivity, alternative answering arrangements and your fallback requirements during scoping.
A migration checklist for your current environment
- Identify the carrier, service type, account owner and numbers that must stay reachable.
- Inventory phones, headsets, analog devices and gateways connected to the current system.
- Document reception, transfers, queues, voicemail and out-of-hours routing.
- Confirm commercial terms and carrier eligibility before cancelling an existing service.
- Agree the cutover contacts, test calls, rollback/fallback arrangements and training.
Accept the result before closing the project
Test the agreed routes from relevant external networks, check caller identification and verify answering on the intended devices. The written scope should identify who accepts the result and the support contact after handover.
Prepare for a business-number move and compare the deployment models.
A cutover decision record
Agree these decisions before the migration date. Name the responsible person and record whether each item is confirmed, pending or not applicable.
| Decision | Evidence before approval | If not ready |
|---|---|---|
| Number move | Carrier eligibility and agreed change window | Keep timing unconfirmed |
| Call routes | Results for agreed incoming, outgoing and transfer tests | Resolve and repeat failed tests |
| Special-purpose devices | Separate assessment of relevant analog equipment | Retain the existing arrangement until assessed |
| Staff readiness | Training and support contact communicated | Complete the missing handover |
| Fallback | Action, trigger and responsible person documented | Do not assume a move can instantly be reversed |
| Acceptance | Named business owner signs off the agreed checks | Keep unresolved items open |
A checklist supports the business decision; it does not guarantee portability or uninterrupted service. Cancel an old service only when the agreed migration conditions permit it.
