Cloud PBX / Hosted PBX platform and Cloud Call Center with PortaSwitch

Deliver a business communication environment to your SMB and enterprise customers with PortaSwitch – voice, video, CCaaS, CRM integrations, and more.

In todays PBX market...

Hosted PBX and cloud-based PBX / UCaaS providers are losing money, losing their competitive advantage, and losing control over their solutions – and their customers. They know that its no longer possible to offer only cheap voice calls’ or ‘cloud PBX’ and expect to be competitive or profitable.

If this sounds familiar, you might be experiencing the following:

Youve been forced to move to SaaS

so you don’t control product development, integration, or troubleshooting. You’re left to resell the same solutions as your competitors, locked out of the ability to offer popular new tools like CCaaS.

Your PBX provider has been acquired

by a large corporation that is less worried about updates. That means you’re losing new sales as your system becomes more and more outdated.

Your customers are fleeing

to new-age platforms such as WhatsApp, Slack, or MS Teams.


Tatyana Massalskaya

PortaOne Head of Marketing

Cloud PBX customers are demanding more functionality, cheaper prices, and additional cloud contact center seats from CSPs – all while per-seat and per-active-call licensing fees drive margins downward and put the squeeze on growth.

PortaSwitch comes with the very unique offering of an unlimited perpetual license: we do not charge you per subscriber, so you can maintain a predictable total cost of ownership. That means your business telephony service can grow with your customers – while your profits grow, too.

How you benefit

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

Paul de Haan

former Senior VoIP Specialist/Architect at Breezz (now part of VodafoneZiggo)

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


Gert van den Berg

Founder of Breezz (now part of VodafoneZiggo)

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).


Krzysztof Zych

former Group Head of IT of GTS Poland now part of T-Mobile

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.
