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.

Your Numbers: Live on day one

Migrating to Wildix doesn’t mean you have to change your number provider. You can keep your existing carrier and connect it to Wildix, so your numbers stay exactly where they are with no porting required.
If you do choose to move your numbers to CLASSOUND, Wildix’s own fully integrated cloud-based VoIP carrier service, Instant Virtual Porting means there is no lengthy wait.

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.”

“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.”
