What is a Class 4 softswitch?

A Class 4 softswitch connects VoIP carriers and routes wholesale call traffic between them, rather than serving end users directly. It decides which carrier carries each call, rates it in real time and keeps a record for billing.

Our Class 4 softswitch gives you that routing and rating in one platform, with the security and failover a carrier-grade business needs, and can be customised to your routing rules.

Built for

  • Wholesale VoIP carriers
  • Traffic aggregators
  • SIP trunk providers
