Recording reset and retention terms require confirmation.
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.
Compare complete monthly costs
Enter the future costs from your quotation. Without those costs we show a software-only difference, never a savings claim.
The comparison uses the selected office package. Enter zero only if your quotation confirms no cost. Usage, contract exit charges and future price changes may affect the result. Annual commitment does not establish the payment schedule.

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.
