Actions for an incoming call

When you receive an incoming call or invitation to a conference, a push notification displaying the username or event name will appear.

How to make a call

Call a user

To make a call to a user, go to the Contacts section. Click on the user's name, and you will then have access to the following buttons:

– user profile;

– audio call;

– video call;

– chat with a user.

To view the call and conference history, go to the Calls section.

Here you can see the history of your calls, including the conferences you have participated in.

During a call, you can use the built-in iOS/iPadOS features to enhance your voice and video. Below is a detailed description for audio and video.

Call to a phone number

To make phone calls, the server administrator must set up integration with the corporate PBX gateway.

From the address book search field

Enter the phone number in the input field in the international format and tap on the call button in the menu that will be displayed below. For example, to make a call to our sales department, enter +1 833 878-32-63 and tap on the call button.

For example, if a user has a 910 extension number, enter the string in #tel:910 format in the search field of your address book to make a call.

Dialer call

You can call a phone number from TrueConf applications using the dialer. Go to the Calls section and click the button. Enter the user's phone number and press the call button.

Call via SIP/H.323

To call a third-party device or server, use the call string format that corresponds to the type of the call destination.

Supported devices and call string formats:

• SIP endpoints (including DTMF commands)
• H.323 devices
• RTSP devices.

Utilizing the built-in iOS/iPadOS features for enhancing integrated video and audio

To utilize the video and audio enhancement features built into iOS/iPadOS:

1. During a call, swipe down from the top-right corner of the screen to open the Control Center.

1. Tap the TrueConf controls to access audio and video settings.

These features are available for iOS 15+ on devices powered by A12 Bionic chip and later.

Audio settings

The following audio modes are supported:

• Automatically — the feature automatically selects the optimal microphone settings for various communication scenarios. For example, when using a headset, Voice Isolation Mode is activated, whereas a standard setting for natural audio capture is applied when using a built-in microphone.

• Standard — standard voice processing is used.

• Voice Isolation Mode — this microphone operation mode uses machine learning to separate your voice and remove background noise. For example, engine noises outside the window or a dog barking nearby will not interfere with your communication.

• Wide Spectrum Mode — this microphone operation mode allows capturing and transmitting all outside sounds. This feature can be useful for immersive online lectures and other use cases when you need to transmit all sounds around you to meeting participants.

Video Settings

The following modes are available for configuring your video:

• Portrait — a feature that allows background blurring. This function can be used for both point-to-point calls and video conferences. By pressing , a menu will expand where you can increase or decrease the blurring effect.

• Studio Light — this effect allows you to darken the background and illuminate the face without using additional equipment. It is especially useful when shooting in low-light conditions, such as with backlighting when the subject is positioned in front of a window. Click to adjust the intensity of the studio light.

• Reactions — during video conferences, you can use full-screen video effects and add reactions with hand gestures that fill the frame with 3D effects. Learn more about all reactions in the Apple documentation.
