01

Authentication and transport

Use IP authorization or generated SIP credentials. TLS is preferred for credential trunks, with strong secrets shown once and rotated on demand.

  • IP allowlisting
  • TLS, TCP and UDP policy
  • Codec controls
  • Failover addresses
02

Limits at the edge

Every trunk is bounded before traffic reaches a wholesale route.

  • Concurrent call limit
  • Calls-per-second limit
  • Country allowlist
  • Maximum call duration
03

Transparent operations

CDRs, wallet entries, rates, SIP responses and support references are visible without exposing wholesale carrier details.

  • Searchable CDRs
  • CSV exports
  • Credential rotation
  • Call-linked support
