A carrier connection is the organization-owned security and policy boundary for a SIP carrier. It can define:
  • provider and display name;
  • active/disabled status;
  • whether inbound calling is enabled;
  • outbound digest authentication;
  • inbound digest or source-IP authentication;
  • allowed source CIDRs;
  • CPS, concurrent-call, and daily-minute limits;
  • codecs and media capability flags.
Carrier secrets are encrypted in control-plane storage. Public responses expose booleans such as has_outbound_credentials rather than returning stored secrets.

Validate a connection

POST /v1/carrier-connections/{carrier_connection_id}/validate performs bounded validation, including SIP endpoint checks. The response reports an overall valid flag, issues, endpoint reachability, response code, latency, and error details when present.

Source-IP authentication

Add a trusted CIDR with:
Active source-IP policy is applied to new carrier traffic without requiring a customer-visible runtime restart.
