Starting a carrier business should not begin with hiring engineers to build a switch. Celvesta gives new and growing carriers a dedicated, branded switch that is installed, updated, backed up and monitored for them. You spend your time on customers, routes and rates.

We build on proven open-source carrier technology and add our own branding, installer and day-to-day management. Every client runs on a separate instance, so your traffic and data stay yours alone.

Next we are adding tools for US carriers: DNO filtering, scam call detection and audit-ready reporting, to help you meet your robocall mitigation duties.

• Dedicated by default

  One client, one server. No shared tenants.

• Managed for you

  Updates, backups and monitoring are part of every plan.

• Straight about the roadmap

  We mark what is coming soon and never list features we have not built.
