Cloud Migration: Move your communications to the cloud without disruption
Wildix makes cloud communications migration seamless, from legacy systems to secure, cloud-native communications.
Businesses Are Migrating Their Legacy PBX to the Cloud
Your PBX wasn’t built for how business works today
Legacy phone systems were built for a different era of business. But as your businesses have evolved with distributed teams, hybrid work and new locations, your infrastructure has fallen behind.
Does this sound familiar?
- Your PBX vendor has announced end-of-life for your system: The longer you stay on unsupported hardware, the greater the risk to your business.
- You're opening a new office and can't scale quickly: What should take days takes weeks, and costs more than it should.
- Expensive contracts leave your IT team stretched thin: Every hour spent firefighting legacy infrastructure is an hour not spent moving the business forward.
- You're merging with another company or enabling remote work: Your infrastructure wasn't built for it, and making it work is becoming more trouble than it's worth.
- You want to automate processes or explore AI: Your current system can't support it, and you're falling behind businesses that already have.
Legacy PBX vs Wildix: The cloud migration benefits
Legacy PBX | Wildix | |
|---|---|---|
Setup | A technician needs to visit your site to plan, install and configure. Service disruption is part of the process. | Deployed remotely in minutes. No onsite visit, no downtime. |
Updates and maintenance | Hardware-based systems require a technician on-site to fix, update or reconfigure. Your team owns the problem. | Handled remotely by the Wildix partner. Nothing for your team to manage. |
When something breaks | Your responsibility to diagnose and resolve, often requiring a site visit and/or significant downtime. | Dealt with at the platform level, remotely and fast. |
Security | Your responsibility to maintain and update. | Enterprise-grade, built in and managed for you. |

What our Customers are Saying

“Having looked after Pellys’ communications for more than 15 years, I can say with certainty that the flexibility Wildix gives them has been invaluable. In the past, closing or relocating offices would have cost them a fortune in new hardware. Now, they simply reassign licenses at no extra cost. That change alone has saved them £20,000, savings that simply wouldn’t have been possible with a traditional PBX system.”

“When it comes to the two most significant benefits of implementation for Wildix, one of them will be future-proofing: the fact that it’s Cloud-based, and how easy it is to upscale it through the business through any growing sites, or adding additional users — that is one of the key elements.”

Technical Director,

“I think Wildix was very fast. It was set up very quickly by Yoozoom — we had virtually no downtime at all. It’s also proved invaluable. Cloud-based is definitely advantageous these days.”
