Concurrent calls describe PBX capacity, not a purchase of telco lines. We confirm how internal calls, transfers, queues and external calls use that capacity before ordering. External telco capacity is sized separately.
Prices and package allowances checked against the LinkusPBX published plans on 2 October 2026. Monthly rates require an annual commitment. Payment schedule, applicable tax, setup, telco, calls and add-ons are confirmed in your quotation.

*The source marks these integrations with an asterisk without explaining conditions. We confirm licences, implementation scope and any charges. WhatsApp, SMS, Teams and smart features are platform capabilities; package availability and third-party costs require confirmation. The source does not specify whether the 500 recording minutes reset, or the recording retention period.

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.
From requirements to a working office setup
Assess users and peak demand
Identify staff needing extensions, where they work and which teams answer incoming calls. Check peak conversations separately from headcount.
Choose supported endpoints
Review desktop, mobile and web clients alongside compatible desk phones. Assess existing analog devices or gateways before assuming reuse.
Test and hand over
Agree incoming/outgoing call tests, transfers, voicemail, administrator responsibilities and staff training before cutover.
Keep the service dependencies clear
The PBX package, external carrier capacity and local network are different parts of the design. A suitable software tier does not purchase telco service, confirm number eligibility or guarantee that every connection and device will work without assessment.
Understand extensions and call capacity, check network readiness and compare complete package rates. Choosing a provider? See our cloud PBX Singapore provider guide.
