VPX Carrier Voice
Global wholesale voice termination for carriers, diallers and IVR platforms.SIP interconnect, dynamic QoS routing, A-Z routes to 200+ countries.
What it
does
VPX Carrier Voice is the wholesale voice platform of the VPX Ecosystem: routing and termination that connects carriers, service providers and enterprise platforms to destinations in 200+ countries. Routing decisions are driven by dynamic rate tables that actively manage QoS parameters and seize opportunities within the spot market, keeping you competitive without sacrificing call quality.
Where most carriers penalise short duration traffic, we are built for it. VPX Carrier Voice is purpose-designed for contact centres, IVR platforms and voice broadcasting providers - supporting CATI surveys, ringless voicemail drops, voice broadcasts and live transfers with route diversity and call completion rates that diallers demand. We aggregate the top dialler termination carriers into a single, competitively priced product so you don't have to manage multiple supplier relationships.
Interconnect is established via SIP (RFC 3261). Rate tables are delivered via REST API or flat file on an automated sync schedule. Billing is per-second with full CDR export via SFTP or API, and settlement is available in GBP, USD and EUR.
The process,
step by step
From first peering session to live traffic - a straightforward path with no hidden complexity.
Interconnect Setup
Establish a SIP peering session with the VPX platform. Our team handles configuration validation and quality testing before the route goes live.
Rate Table Delivery
Receive your rate tables via REST API or flat file (CSV/XLS). Tables are updated on a scheduled sync so your LCR engine always reflects current market pricing.
Traffic Routing
Send traffic across the agreed interconnect. The VPX routing layer evaluates route quality - ASR, ACD, PDD, NER - on every call attempt and selects the optimal path in real time.
Quality Monitoring
Access per-destination quality metrics via the live portal dashboard. Alerts fire automatically on quality degradation so issues are caught before they affect your traffic.
CDR & Settlement
Full CDR export at per-second granularity via SFTP or API in CSV or JSON. Settlement in GBP, USD, or EUR with dedicated account management.

Built for
performance
Every capability is designed around real-world wholesale requirements - not a feature checklist.
Four route classes. Pick the one your traffic needs.
We do not publish a rate card: every client gets rates for what they send and what the market is doing that day. What we do publish is what each class is for.
Under the
hood
One connection, everything accessible
Rate tables, CDR feeds and quality metrics are all available programmatically. Interconnect via SIP - no proprietary hardware or specialist integration work required.

Get in touchWhat carriers ask us before they connect
How do I get rates?
Apply online. Once your account is approved, we send your rate deck by API or file, per route class. Rate increases come with 7 days' notice; decreases apply at once.
How do I pay?
Prepay first. Usage can be billed after the event only against a credit limit we approve in writing. Billing increments are set per destination and published in our Carrier Billing Policy.
What do you need from me to go live?
Your company and ownership details for our KYC and credit check, your traffic profile, and your SIP details. You sign our interconnect agreement online, we test the route with you, then it goes live.
How do you handle fraud?
Fraud-prone and premium destinations are blocked by default, and every number is checked before we connect it, at no charge. You are responsible for all traffic sent from your account, so tell us at once if your system is compromised.
Which codecs and fax do you support?
G.711 and G.729 on every trunk. HD voice (G.722 and Opus) and T.38 fax are available on request for your trunk.
