Services

Everything a wholesale voice operation needs.

Six service lines, delivered over one interconnect and one commercial relationship.

Voice termination

Wholesale A–Z and premium routes across 150+ countries, with route profiles selected for ASR and ACD rather than headline rate alone.

  • CLI and non-CLI route options
  • Per-destination quality targets
  • Competitive per-minute pricing

SIP trunking

Scalable trunks for PBX and UC platforms, with capacity that adjusts to your traffic profile instead of fixed channel blocks.

  • Elastic concurrent-call capacity
  • IP or credential authentication
  • Multi-site failover

International DIDs

Virtual numbers in 60+ countries for local presence, with provisioning and porting handled through one interface.

  • Local, national and toll-free
  • Number porting
  • Flexible inbound routing

Carrier interconnect

Direct IP and TDM peering with tier-1 and regional operators, shortening routes and removing intermediate transit hops.

  • Direct IP peering
  • TDM where required
  • Route optimisation

Fraud & security

Continuous traffic analysis with anomaly alerting, so IRSF and traffic pumping are caught while they are still small.

  • Real-time anomaly detection
  • Destination and spend caps
  • DDoS mitigation

CPaaS & APIs

REST APIs for voice, SMS and messaging so communications can be embedded directly into your product.

  • Programmatic provisioning
  • CDR and reporting endpoints
  • Webhook event delivery

Network

How your traffic actually flows.

Every call enters through a redundant edge, is scored against live route quality, and leaves over the best available path — with automatic failover if a route degrades.

Simplified call path. Failover and re-routing happen at the route engine, not at your switch.

Infrastructure

  • Redundant multi-carrier routing with automatic failover
  • Distributed points of presence across multiple continents
  • Real-time traffic analytics and per-destination reporting
  • DDoS protection and fraud detection at the edge

Operations

  • NOC monitoring with defined escalation paths
  • Quality reviewed per destination, not just in aggregate
  • Change windows communicated in advance
  • Named commercial and technical contacts

Coverage

Reach, by service line.

Rates and per-destination quality figures are issued per account, against your actual traffic mix — a published A–Z sheet rarely reflects what a given profile will really see.

Some destinations require documentation before activation — local presence, end-user registration or regulatory filings. We confirm these during technical review, before you commit traffic.
