Clear CLI on every call, per-second billing and a portal you can hand to your customers. SIP termination, DID numbers, SIP trunking and a white-label reseller program for VoIP carriers and ITSPs, CPaaS and AI voice platforms, cloud PBX operators, white-label resellers, enterprises, small businesses and contact centers.
Large carriers treat you as a traffic source. Grey routes treat your calls as inventory. Callivex is the carrier on your side of the call.
Your CLI is presented intact on every route, never stripped, never substituted. Your number arrives as your number, and your answer rates show it.
Every connected second billed as a second, five-decimal rates and a prepaid balance you watch in real time. The rate you test is the rate you run.
Direct EU carrier interconnects, and direct access to the engineers who operate them. No ticket queue between you and an answer.
Every account gets dedicated channel capacity sized to the traffic you actually run, burstable on request. Limits are per account, so one customer's peak never touches another's traffic.
Three layers of pricing get composed automatically. Wholesale cost on the bottom, your platform margin in the middle, the reseller's margin on top. Every CDR is split per second, balances drain in real time, and calls cut at zero.
Every call passes through one core that authenticates it, picks the route and rates it per second in real time. We do voice transport and nothing else.
A-Z outbound voice on direct EU carrier interconnects. Stable routes with clear CLI delivered end-to-end, per-second billing with five-decimal rate precision.
