How you benefit

Experience a solution that will make your business run smoother, quicker, and even happier.

Reduce costs and increase confidence, knowing that perpetual licensing means your prices won’t increase
Save time on regular maintenance like fixing bugs by accessing our tech support – on call 24/7
Allow anyone on your team to develop and integrate new features with our low-code development platform and open architecture

Breezz has utilized PortaSwitch to support 80+ white-label resellers of hosted PBX services. Its open architecture allowed us to bring new product options to the market quickly; and the reliability enabled to do all this with only 2 engineers in the team initially.

Within 6 years we were the largest supplier of hosted PBX / SIP trunking service in the country with over 100.000 active users total.

Act fast!

Waiting means losing traction and getting left behind.

Consumers are already becoming comfortable with ‘new-age’ platforms like Messenger, WhatsApp and Teams.

Waiting could mean losing your current customers, forcing you into the high expense of looking for brand-new customers.

The PBX and UCaaS segments are seeing huge growth. Enterprise customers want access to tools like a mini cloud contact center, customer self-service, virtual receptionists, and more. Become an early provider and reap the benefits first.

What customers say

Our initial goal was to challenge the major incumbent in the Netherlands – KPN – with a VoIP platform that could offer more retail features at a competitive price.

Finding an independent technical platform versatile and scalable enough to support the task, provided difficult – until we found PortaSwitch.

Within 6 years we became the largest supplier of hosted PBX / SIP trunking service in the country with 35,000 SMB customers (over 500.000 phone lines).

While managing IT infrastructure of GTS Poland, the PortaSwitch system operated so smoothly and the PortaOne team managing it produced so few escalations that when I met them at a trade fair recently, initially I could not even recall their names.

I wish every operator would have as many systems as PortaSwitch that work properly, generate revenue, and allow executives to focus on their job.

Cloud PBX FAQ

What is a Cloud PBX and how does it benefit businesses?

A Cloud PBX (Private Branch Exchange) is a virtual phone system hosted in the cloud, enabling businesses to manage calls, voicemails, and extensions without on-premise hardware.

With PortaOne’s Cloud PBX platform, service providers can offer flexible, reliable VoIP services, with advanced features like call forwarding, auto-provisioning, and more.

How does a Cloud PBX differ from a traditional PBX system?

Unlike traditional PBX systems relying on physical hardware and PSTN lines, Cloud PBX operates over the internet using VoIP technology. This eliminates costly maintenance, supports remote access, and offers modern features such as video conferencing and AI-powered call routing. PortaOne’s platform enables service providers to deliver easily scalable UCaaS (Unified Communications as a Service) to clients, combining voice, video, messaging, and collaboration tools in a single cloud-based offering.

What features should I look for in a Cloud PBX solution?

If you’re a service provider looking for a Cloud PBX platform, you need the ability to scale up quickly, to offer excellent customer service, and to create specialized products and packages for your niche.

Your platform should be white-label, so you can customize it to promote your own brand. Look for real-time billing to support your bottom line, and an unlimited perpetual license to support your growth.

How does PortaOne’s Cloud PBX support business growth?

PortaOne’s Cloud PBX empowers businesses with a cloud telephony solution that is quickly scalable as you gain new clients. It integrates easily with existing CRM, IoT, and UCaaS platforms, lowering start-up or platform switching development costs. Its open architecture and comprehensive API allow extensive customization, while real-time billing with no per-user fees maximizes profitability. Trusted by over 500 telecom operators worldwide, PortaOne supports rapid service deployment and enhances customer experience.

Can cloud PBX integrate with other business tools?

Yes, a reliable Cloud PBX seamlessly integrates with CRM, ERP, and other enterprise systems to streamline communication workflows. PortaOne supports low-code integrations with platforms like Microsoft Teams and offers an Add-on Mart marketplace for various add-ons, helping businesses unify communications and improve operational efficiency.

PortaOne’s open API philosophy supports the diverse needs of telecom providers. If your team uses tools like a CRM or accounting system, PortaOne makes low- or no-code integration possible, via the API or PortaOne Workflows.

Already using a CRM with a web dialer? PortaOne’s partnership with PressOne enables calls directly from HubSpot, Freshdesk, or Zoho, and links incoming calls to contacts. These features are available through the Add-on Mart (PortaPhoneCRM modules). The result: streamlined workflows and unified communications.

What role does AI play in modern Cloud PBX systems?

Innovation-seeking service providers are asking Cloud PBX platforms to stay at the cutting edge of technology. PortaOne has answered the call, seeking ways to use AI to bring smart features to Cloud PBX systems, such as:

Call transcription: automatic speech-to-text for recorded calls, enabling faster review and insights (e.g., using OpenAI Whisper)
AI-powered analytics: using AI workflows to process transcripts and extract meaningful insights (e.g., sentiment or topic analysis) for CRM integration
Call routing: AI agents trained on business rules can route through the lowest cost providers to help lower the costs of doing business

These AI capabilities help service providers offer advanced Cloud PBX services with enhanced automation, better customer experience, and new monetization opportunities.

How do I choose the right Cloud PBX platform?

Choosing the right Cloud PBX provider depends on your business needs and technical priorities. Most companies look at things like integration with existing tools, scalability, cost, security, and customer support.

To help you navigate the decision, PortaOne created a comprehensive Cloud PBX Checklist. It outlines the most important criteria for selecting a cloud telephony platform — from must-have features to deployment options and compliance.
