You can rest easy when you choose OnSIP as your business VoIP provider. Forget about dropped calls, poor sound quality, and constant service interruptions. Our patented technology allows for geographically distributed, redundant data centers, meaning we keep your service running no matter what.

  • Built from scratch: We built our phone system from the ground up, opting for a customer-friendly distributed structure. If one part goes down, we can easily move our customers to a different data center.
  • Flexible: We register our customers’ VoIP phones to the closest data center, allowing for software upgrades with no service interruption and optimal call sound quality.
  • Scalable: We can easily scale out our platform by adding new servers in our data centers as needed.
