When you receive an incoming call or conference invitation, the username (or event name) will be displayed. The call type will also be indicated: TrueConf audio call or TrueConf video call.

In addition to the buttons for accepting and declining a call, the following actions will be available to you:

/docs/client-android/media/gui/incoming_call_message/en.png – send a message instead of answering the call. You can choose a quick response from the default options or write your own message. It will be sent to the caller, and the call will be automatically declined. This feature is available for incoming one-on-one audio or video calls and invitations to an ongoing conference from one of the moderators.

/docs/client-android/media/gui/incoming_call_mic/en.png – accept the call with the microphone on, or mute it in advance /docs/client-android/media/gui/incoming_call_mic_off/en.png.

/docs/client-android/media/gui/incoming_call_cam/en.png – accept a call with the camera on, or disable the camera in advance /docs/client-android/media/gui/incoming_call_cam_off/en.png.

/docs/client-android/media/gui/incoming_call_speaker/en.png – accept the call using an ear speaker or loud speaker /docs/client-android/media/gui/incoming_call_speaker_2/en.png. If a Bluetooth headset is connected to the smartphone, you will see the corresponding icon /docs/client-android/media/gui/bluetooth/en.png.

# Call to a phone number

To make calls to a phone number, your TrueConf Server instance has to be integrated with the gateway of a corporate PBX.

# From the dialer

TrueConf applications also allow users to make calls to phone numbers from the dialer where you can find the list of users whose phone numbers are registered on the server.

The dialer can be opened by tapping the /docs/client-android/media/gui/dialer/en.png button on the Calls tab.
