These numbers connect to a useful IVR script to help with audio quality, DTMF testing, and a simple conference bridge. I use this test script almost daily when I'm working with phones, WiFi, smartphones, soft clients and trying to figure out why calls sound awful.
Menu options include:
- Record and playback, the most requested feature, use the # key to stop the recording
- DTMF testing - Enter a long string of DTMF keys and press # to get a read out
- Real time Echo test
- Playback Music on Hold
- Test conference bridge
- 0-4Khz audio sweep
- Caller ID readback
- Real time DTMF test (instant readback of key pressed)
- Asterisk Milliwatt tone
