Before testing

  • Confirm whether authentication uses source IP, registration, or another assigned method.
  • Exchange signalling addresses, ports, RTP ranges and allowlisted IPs.
  • Confirm number format, codecs, DTMF mode and concurrency.
  • Prepare inbound, outbound, answer, reject, no-answer and hang-up test cases.

Production note

Important

The SIP FQDN, ports, authentication, codecs, DTMF mode, capacity and media security are project-specific. Confirm them with VonnexAI technical staff before configuration.
