Wholesale SIP termination is outbound calling to any destination, bought in volume over a SIP interconnect and billed per destination. Callivex delivers it on direct EU carrier interconnects, for VoIP carriers and ITSPs, CPaaS and AI voice platforms, cloud PBX operators, white-label resellers, enterprises, small businesses and contact centers, from a single trunk to carrier-scale interconnects.
Your calling-line identity passes intact from your SBC to the destination network - never stripped, never substituted. Higher answer rates on EU and North American termination.
Direct carrier interconnects with consistent quality, so the ASR you test with is the ASR you run with.
ASR and PDD monitored per destination in real time, with ASR-weighted carrier failover. Degrading routes are pulled before your campaigns feel it.
Whether you run a ten-seat office or a large dialer operation, your account is sized for the traffic you actually run, with capacity sized to your peaks, burstable on request.
Every second of every connected call is rated. Five-decimal precision keeps long-tail destinations economic. Real-time CDR streaming so your platform can react inside seconds - not at end-of-day.
Routes aren't ordered by price. Each destination has a primary, a backup, and a fallback, weighted by recent answer-seizure ratio (ASR) and post-dial delay (PDD). When a route's quality drops, traffic shifts within minutes, not at the next quarterly review.
Wholesale termination is a regulated service. Onboarding is intentional, not instant.
