# Setting up the application
This section presents various application settings responsible for its behavior in conferences, appearance, notifications, and much more. In addition to changing the application's operating parameters in the Settings section, you can:
go to your profile;
request a PRO license;
go to Favorites.
# Conference
In this section, you can flexibly configure the conference's main settings, audio, and video. We will discuss this in more detail below.
# Main
In the General section, the following settings are available:
Accept new conference participants automatically – if you are the owner of an active conference and a user calls you, they will be automatically added to the conference;
Receive calls only from my contacts – you will receive incoming calls and conference invitations only from the contacts in your address book; other users will not be able to call you.
Show the preview window before joining a conference – the window for selecting equipment and other settings is described in detail here. You can disable it to avoid configuring the equipment each time.
Number of video windows in the conference layout – by default, the layout displays 4 participant video windows, with the remaining video windows placed on additional screens. You can change the number of visible windows to any number between 1 and 20. Below is an example with 1, 4, and 14 video windows.
# Audio
Join with microphone – the behavior of your microphone during an incoming call or conference invitation.
Voice Activity Detection – highlighting the active speaker with an orange border in the video layout and in the participant list of the conference.
# Video
Join with video – the behavior of your camera during an incoming call or when invited to a conference;
Virtual background – a feature for changing the background, where you can also activate the blur effect. Similarly, the blur effect can be enabled in the video settings of your device. You can choose one of the standard virtual backgrounds or upload your own by clicking the
button.
The switcher Video quality optimization is activated by default. In this case the video received during one-on-one calls will have smaller resolution which is needed for reducing the use of device resources and network load.
Use Hardware H264 Codec – enables the use of the built-in H.264 hardware codec, which positively impacts the device's power consumption and performance when using the application.
H264 codec is enabled by default because it is built into iOS at the hardware level and consumes much less resources than the software codec.
# Network
This settings section is responsible for the application's network parameters.
In the Connected to section, the address of the TrueConf Server you are connected to is displayed.
Below are the parameters:
Direct Connection – connection during a point-to-point video call will be conducted directly, bypassing the server;
Use system DNS – allows the use of the system DNS server in networks with complex configurations. By default, this option is disabled;
We do not recommend enabling this option unless necessary, as its operation may negatively affect connection stability.
Keep the Check for available servers in LAN when launching the app switcher active to make sure that the application can detect available instances of TrueConf Server in the corporate network.
View list – to view the list of available servers.
The Bandwidth Control section enables you to adjust your network settings.
In the case of using a low-speed internet connection, for example, 2-3 Mbps, you can limit the bandwidth consumed by the client application. As a result, the quality of your video will be reduced, and the load on the communication channel will be decreased, allowing other applications to operate more stably.
For detailed guidance on configuring channel limitations in your organization, please contact your server administrator.
# Notifications and sounds
In TrueConf for iOS/iPadOS, two types of notifications are implemented: system and built-in.
System notifications work when the application is closed or the device screen is locked. Their behavior is controlled by the OS settings.
Built-in notifications are used when directly working with the application. The sound of these notifications can be turned off in the corresponding section:
After enabling the Show system messages in conference chat option, you will receive notifications of the following types:
# Miscellaneous
To enable the display of users categorized by groups in the address book, activate the Display contacts by groups toggle switch.
# Group management
To create a group, proceed to Options → Other → Group management → New, enter the group's name and tap the Create button.
# Editing or deleting groups
To delete or edit a group:
Go to the list of groups in the address book (if they are not visible, enable the group display).
Find your group, tap the
button opposite its name and choose Edit Group or Delete Group in the pop-up menu.
# Data and Memory
TrueConf for iOS/iPadOS caches all media files downloaded on your device. To check or limit the size of cache, go to the Storage management section.
To delete cache, tap on the Clear Cache button; otherwise, just select the maximum size so that the application could automatically free up space when the limit is reached.
In the Automatic downloads section, you can select the type of network for automatic downloading of images in chats. If you are in group chats with a large exchange of images, activate the Never option to save cache volume and traffic. In this case, images will need to be downloaded manually.
If your mobile plan has limited internet data, we recommend selecting the Wi-Fi option.
# Appearance
In the Appearance section, you can change the application theme.
By default, the system theme is used. Switch to the Light or Dark option to change the application to the respective mode.
Below you can set the color scheme for the application. The selected color will be applied to your messages, icons, and other interface elements of the application. The appearance of the application with a dark theme and modified accent color:
Additionally: for the Home screen, you can replace the original app icon with
