About Callivex

We sell voice wholesale, by the second, on direct EU carrier interconnects. The same network serves office PBXs, enterprises and contact centers. Resellers get a white-label portal under their own brand.

We provide the voice transport layer for cloud PBX, unified communications and contact-center platforms.

Operated by its engineers, not a sales floor. The person who answers your email is the person who configures your trunk. We pick up the phone when something breaks and explain what is happening when an upstream carrier has an incident.

What we say we do, we do.

Honesty about scope. We list what we offer and not what we'd like to offer. If we don't have the route, we'll say so.

Honesty about quality. ASR, NER and PDD are visible to every customer.

Honesty about price. We price for routes that stay on quality.

Honesty about incidents. When something breaks, we tell affected customers within the same hour, in plain English, with what we know and what we don't.
