Carrier Integration

Technical onboarding of carrier interconnects—SIP profiles, testing, failover, and ops handoff.

Bringing a new carrier online is a technical project, not just a signed rate sheet. We handle SIP profile setup, test vectors, codec/CLI expectations, failover behavior, and the runbooks your NOC needs when the carrier side misbehaves—so interconnects become operable assets instead of fragile tribal knowledge.

Who it’s for

  • Carriers adding peering partners
  • Aggregators expanding interconnect footprint
  • Enterprises dual-homing voice providers

Problems we address

  • New carriers go live without a repeatable test plan
  • CLI, codec, or timer mismatches cause intermittent failures
  • Failover between carriers is unproven

Expected outcomes

  • Structured interconnect onboarding checklist
  • Profile configuration and acceptance testing
  • Documented failover and escalation paths
