Voice Mail Test

To test the modem’s voice function:

1. Set up the MultiModem for voice mail.

2. Use another phone to call and leave a message and then play it back.

If your modem does not play sound files in voice mode:

1. Open the Windows Control Panel and double-click the MultiModem icon.

2. Click Audio tab, select Modem Wave Driver as your preferred device for both playback and recording.

3. Repeat the voice mail test.

Loopback Test

1. Connect a microphone and speaker to the modem. To avoid feedback, separate the microphone and speaker

or use a headphone instead of a speaker.

2. Select Start, point to Programs, point to Accessories, and click HyperTerminal.

3. Click Cancel in the Connection Description dialog box.

4. In the HyperTerminal terminal window, type AT&&S and press Enter. This command causes input from the

microphone to be looped back to the speaker.

5. Speak into the microphone. You should hear your voice on the speaker or headphone.

6. Type ATZ and press Enter to reset the modem.

Speakerphone Test (with voice option)
