# I talk but no-one can hear me.

Should you find that the medical provider or the patient cannot hear you during the call, it might be one of the following reasons.

Check that you have sufficient bandwidth and that your device is connected to the internet.

To successfully conduct a call, you must ensure that your device has the necessary microphone feature. The device you are using will determine the set-up procedures should you use an external microphone.

When using the external microphone do ensure it connects successfully using Bluetooth or that your microphone jack is correctly entered into the device.

After troubleshooting the above steps successfully, check that your session is not muted on the call.
