What does the SIP Route Tester measure?

The SIP Route Tester measures audio quality, CLI presentation and DTMF (touch tone) functionality.

  • Audio Quality - Spearline will provide you with an in-country toll number to dial out to. These numbers are set to auto answer incoming calls and playback Spearline's audio quality prompt, allowing us to measure the audio quality on the outbound call.
  • CLI - The SIP Route Tester allows you to set whatever CLI you require for each carrier tested. Because you are dialing out to a Spearline number, we can report on how that CLI is presented at the terminating end.
  • DTMF - Spearline numbers also send DTMF tones before the audio quality prompt is played, allowing us to report if these tones are received at the origination point.
