Softswitch modernization with safer routing, fraud controls, and operator dashboards.

Problem

Legacy routing was undocumented, fraud spikes were hard to trace, and operator changes were risky.

Solution

We redesigned routing policy, hardened the edge, added CDR visibility, and delivered runbooks for change windows.

Results

  • Mean time to diagnose route issues cut significantly
  • Fraud rule set with alert channels
  • Documented failover path for primary interconnect
