Out of all the tools that IT teams manage, phone systems can often come with highly complex challenges. If you’re part of a global team, you might be juggling multiple providers, each with their own billing, admin portal, and contract. That makes things difficult to manage on your end and can lead to a poor experience for employees.
Or maybe you’ve been looking to migrate to a cloud solution but feel locked into your existing telecom contracts. You’d rather gain the benefits of cloud-based calling than stick with your clunky on-premises infrastructure, but you’re facing costly termination fees if you cancel.
You’re not alone. Many companies are retiring their traditional phone systems in favor of more modern cloud phone solutions, but the migration process isn’t always as straightforward as they’d like. Organizations need flexibility, especially global enterprises that operate in markets where cloud coverage can be limited or regulated. With a Bring Your Own Carrier (BYOC) approach, you can get just that.
Bring Your Own Carrier allows you to keep your existing phone service provider (the ‘PSTN’ public switched telephone network telephony carrier) while moving to a cloud-based phone system. Instead of replacing everything, you can connect your current carrier to the cloud platform using a secure network connection, often through a device called a session border controller (SBC). A BYOC strategy gives you flexibility with your corporate telephony solution and offers additional connectivity options to fit your organizational needs, while still taking advantage of modern cloud features. BYOC provides a clear and manageable migration path from your legacy on-premises PBX to a cloud solution.
As more organizations migrate their phone service to a cloud solution, too many cloud providers require you to go all in with them, which often means abruptly migrating away from your current carrier. With BYOC, you get the benefits of cloud-based communications and the flexibility your current carrier provides. Here are just a few of the benefits of BYOC:
You can bring your own carrier when migrating to Zoom Phone, our cloud-based phone solution that’s part of Zoom Workplace.
