Cloud PBX/Hosted PBX Platform | Single Unified Platform

Cloud PBX spreads across systems as it grows

Margins tighten and the work spreads out.

Per-user licensing eats into margins
Every enterprise customer needs another box
Voice, billing, and provisioning sit in separate systems
Every new service brings another system with it
Resellers add another set of prices and settlements to keep straight
Customers expect more features for less

PortaOne: One platform, one operation

Run the commercial and technical side of Cloud PBX from the same system.

Set your own pricing and reseller margins
Host many business customers as separate tenants on one platform
Run Class 4 and Class 5 together
Bill prepaid and postpaid in the same system
Manage provisioning, customers, and resellers in one place

“We got two big customers; they say the interface looks nice, modern, and they are very happy with it.”

No per-user platform licence

One unlimited perpetual licence covers the platform. What you charge per seat is your decision.

Bill the way your market buys

Per seat, per minute, flat-rate, or hybrid. Prepaid and postpaid can run on the same platform.

Set pricing at every level

Define your own rates, then let resellers build their own plans and margins.

Support reseller chains

Operator → reseller → customer → department, with separate pricing, branding, and account management.

Add services as the business grows

Switch on optional Add-on Mart modules when needed, each with a 30-day trial.

That means Cloud PBX can sit alongside SIP trunking, broadband, MVNO, and other services with:

One customer record
One billing system
One back office
One reseller structure

You add Cloud PBX to the operation you already run, instead of standing up another platform beside it.

Handle calls the way the business works

IVR, hunt groups, call queues, forwarding, recording, conference bridges, and business-hour rules.

IVR, hunt groups, call queues, forwarding, recording, conference bridges, and business-hour rules.

Give users more self-service

Customers and end users manage numbers, forwarding, voicemail, and other settings from their own portals.

Connect the tools they already use

Microsoft Teams, Salesforce, HubSpot, Zoho, Zendesk, Freshdesk, Xero, QuickBooks, Stripe, and other systems through the open API.

Add AI where it earns its place

Voice AI agents, speech-to-text, and text-to-speech are available as optional modules, with a 30-day trial.

Your branding in the app stores

HD voice and point-to-point video calling
Cloud PBX features from mobile and web
A daily touchpoint between your service and your customer

For operators who want the softphone on its own, PortaDialer is available separately.

PortaDialer

Launch or replace your softphone with a branded app built for service providers. Low-risk entry, predictable pricing, and full control across mobile and web platforms.

Provision phones with less manual work

Zero-touch provisioning for Yealink, Polycom, Snom, Grandstream, and Flyingvoice handsets.

Give each user the right level of access

Back office, reseller, customer, and end-user portals keep everyday tasks with the people who handle them.

Handle phone number moves in the same workflow

Number portability runs inside the platform instead of a separate process.

Automate repetitive operations

Low-code workflows reduce manual steps across provisioning and service management.

Keep the features your customers already rely on

Map the incumbent's feature set before anything moves, so end customers do not lose what they use every day.

Import existing subscriber data

Customer, account, and service data migrates across without manual re-entry.

Run old and new platforms in parallel

Migrate in stages instead of moving everyone at once.

Work with dedicated migration engineers

PortaOne specialists plan the data transfer and the cutover with you.

What is a Cloud PBX platform for a service provider?

A Cloud PBX platform is the system a voice provider, ISP, or operator runs to sell hosted phone service to business customers. PortaOne’s Cloud PBX runs on PortaSwitch, which handles Class 4 carrier routing and Class 5 subscriber features on the same platform, together with billing, provisioning, and reseller management. You operate the platform, set the prices, and own the customer relationship.What is a Cloud PBX platform for a service provider?

How is this different from reselling someone else's hosted PBX?

When you resell, you sell another vendor’s product under your name and their platform decides what you can offer and what it costs you. With PortaOne you run the platform, set pricing, configure the service, keep the customer data, and put your own brand on every portal and app your customers see.

How is PortaOne licensed – per seat or per system?

Per system. PortaOne sells an unlimited perpetual licence for the platform, with every function included from the start, rather than charging you per user or per feature. What you charge your own customers per seat is your commercial decision. Optional modules in Add-on Mart are priced separately from the platform licence.

How do I bill Cloud PBX customers?

PortaBilling handles this billing inside the same platform: per seat, per minute, flat-rate or hybrid, prepaid, and postpaid on the same system, with invoicing, taxation and payment collection. You can charge in whichever unit your market buys in – seats, extensions, channels, or minutes – and mix models across customer groups.

Can I serve many business customers from one platform?

Yes. PortaSwitch is multi-tenant, so every business customer is a separate tenant on the same platform, with its own users, extensions, call rules, branding, and billing, isolated from every other tenant. You do not install or license a separate system per enterprise, so the cost of winning the next customer is a configuration, not another system to buy and maintain.

Can I sell Cloud PBX through resellers?

Yes. PortaSwitch supports a multi-level chain: operator → reseller → end customer → department. Each level gets its own branded portal, its own pricing, and the ability to manage its own customers. Reseller margins are settled through the billing engine rather than tracked by hand.

Where can I see the technical details before talking to sales?

See docs.portaone.com, our public knowledgebase. Several thousand pages cover configuration, APIs and every PBX feature. Nothing is behind a login, so you can read it, search it, or point your own AI assistant at it and ask your own questions before you speak to anyone.

Can I migrate from Asterisk or FreeSWITCH?

Yes. Operators have moved to PortaOne from Asterisk and A2Billing builds, and from other systems they assembled themselves. The work is mapping what your customers use today onto PortaSwitch, importing subscriber data, and running both in parallel until the cutover.Can I migrate from Asterisk or FreeSWITCH?
