The SIP Route Tester measures audio quality, CLI presentation, and DTMF (touch-tone) functionality.
- Audio Quality – Spearline will provide an in-country toll number to dial. 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 you’re testing. 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.
