Why Simplicity VoIP

Our own SIP network

No middleman. We run the trunks, so you get better rates, faster fault resolution and one accountable provider.

Yeastar Cloud PBX

A full hosted phone system — extensions, IVR, queues, voicemail and apps — managed from a browser, no on-site hardware.

Keep your number

We port your existing geographic numbers across, so customers reach you on exactly the same number.

Local, hands-on support

South African engineers who set it up, port your numbers and answer when you call.

Yeastar Cloud PBX — your whole phone system in one app

We deploy and manage the Yeastar P-Series Phone System (Cloud Edition) — a hosted, all-in-one unified-communications platform built for South African businesses.

Linkus UC apps

Call from web, Windows/Mac desktop and iOS/Android — flip a live call between devices in one tap.

Smart call handling

IVR auto-attendant, ring groups, call queues, time-based routing and voicemail-to-email.

Recording & reports

Record calls, monitor live queues with the Operator Panel and pull detailed call reports.

Enterprise security

VoIP questions, answered

A hosted PBX is a business phone system run in the cloud instead of on-site hardware. Simplicity provides hosted PBX on the Yeastar P-Series Cloud Edition, so you manage extensions, IVRs and call routing from a web browser for a predictable monthly fee.
A SIP trunk delivers phone lines and numbers to a PBX you already own; a hosted PBX is the whole phone system delivered as a cloud service. Simplicity offers both — SIP trunks for existing PBXs, and fully managed Yeastar Cloud PBX.
Yes. Simplicity ports your existing geographic numbers onto our SIP network, so your customers keep reaching you on the same number.
VoIP works best on a stable fibre or fixed-wireless line. As a KZN ISP, Simplicity can supply the fibre and the phones together and prioritise voice traffic for clear calls.
Calls keep working if your router and phones stay powered — a small UPS or inverter is enough — and the Linkus mobile app or automatic call-forwarding to a mobile keeps you reachable during an outage.
Yes. The Yeastar Linkus app runs on iOS, Android, Windows, Mac and the web, so staff make and take business calls from anywhere and flip calls between devices.
Yes. The Yeastar P-Series encrypts calls with TLS/SRTP and adds two-factor authentication, automatic intrusion defense and STIR/SHAKEN to combat caller-ID spoofing.
Yes. Yeastar integrates with Zoho CRM, Microsoft Teams, Outlook and others for click-to-call and on-screen caller information.
From a single home line to hundreds of extensions across multiple sites — the cloud system scales as you grow.
Pricing depends on user count, numbers and call volumes. Simplicity quotes per business with VAT-inclusive, month-to-month pricing — request a tailored quote.
