An echo test is a feature created to check the quality of your sound and make sure your headset is working properly. It helps you troubleshoot issues with your VoIP calls.

A DTMF test checks that your hardware is sending the correct DTMF signals.

You can perform a self-test for echo and DTMF functionality by dialing 07777712125552665 from any SIP account in the CommPeak platform. This special phone number is free of charge and available to all SIP clients.

Running an Echo Test

To perform the echo test:

1. Log in to the softphone application you use for CommPeak VoIP services.

Below, we give instructions for testing with CommPeak Softphone and Zoiper.

2. On the dial pad, enter *13 and click the dial button.

3. The test call will be placed.

If you’re using CommPeak Softphone, there is another option to run the echo test:

1. Go to Settings and click Test Call.

2. Say something using your computer microphone or headset microphone. Everything you say will be repeated back to you as soon as the machine receives your voice.
3. Check if the sound quality and Network Latency are fine.

NOTE

CommPeak Softphone supports the G.722 Wideband codec that makes HD VoIP possible and can be used only with providers that support that option.

An HD icon appears when the softphone detects wideband calls (HD). This indicates that the call will broadcast in high definition according to the following flow: agent device → dialer → CommPeak → ISP → callee device.

If you have any issues, make sure your Internet connection is stable and that your microphone and headphones are connected. Also, feel free to contact our support team.
