# Main Window

The TeamTalk application consists of a menubar, a toolbar, a channels view in the left side with volume controls below and a tab control with four tabs to the right. Between the channels view and the tab control is a so-called splitter which can be used to change the size of the channels view and tab control.

The following screenshot is included to help explain the TeamTalk application's user interface.

## Menu Bar

In the top of the application are six menu-items: Client, Me, Users, Channels, Server and Help. The Client-menu is for configuring the TeamTalk application and connecting to servers. The Me-menu gives access to options which should be set for the local user (meaning you), like e.g. changing your nickname or status. The Users-menu is used for interacting with other users, like e.g. changing their sound volume or sending them text-messages. The Channels-menu is used for controlling channels, like e.g. creating new channels or updating existing ones. The Server-menu is for changing or viewing the server's options and finally the Help-menu is for assistance.

## Toolbar

The toolbar simply provides easy access to common tasks which are also available though the menu items.

- Connect button
  - The first button in the toolbar, which looks like a plug, is for connecting to a server. Once pressed it opens the Connect to a Server Dialog.
- Enable Push to Talk button
  - The second button in the toolbar, which looks like a button, is for enabling a push to talk button. Push to talk is a key combination which must be held down whenever you are talking. If not push-to-talk key is defined it will open the Push to Talk.
- Enable Voice Activation button
  - The third button, which looks like waves, are for enabling voice activation. Enabling this will make a slider show up in volume controls below the channels view. Move this slider left and right either changes the voice activation level.
- Enable Video Transmission button
  - The fourth button, which looks like a webcamera, is for enabling video transmission. Before this can be used a camera must be set up in the Video Capture-tab in Preferences. Once the camera is started one can click the Video-tab in the tab control to see one self.
- Enable Desktop Sharing button
  - The fifth button, which looks like a blackboard, is for sharing a desktop application with other users in the same channel. A shared will be displayed in the Desktop-tab for other users.
- Mute All button
  - The sixth button in the toolbar, with a speaker icon, is for muting all users in the channel you're participating in, so you can no longer hear them.
- Recording Conversation to Disk button
  - The seventh button, which looks like a record button, is for storing text chat-logs and audio files to disk. See section Record Conversations to Disk on how to record conversations.
- Show Blinking Icon button
  - The last button, which looks like a hand, is for enabling the Question status mode. This will make you appear as a user with a blink hand.

## Channels View

The channels view is in the left side of the application above the volume controls. Once you have connected to a server you will see channels and users appearing here.

The channels will appear as folder icons and the computer icon in the top is also a channel, namely the root channel, where you will first appear when you connect to a server.

The user impersonating you will appear with bold text, so in the screenshot below Bjoern is me. The blue box surrounding the user-icon means that I'm currently transmitting video, so the other users in the channel can see Bjoern in the Video-tab.

The user Ida is also transmitting video but the blinking red line on her name means that the reception from her is very poor (video data is being lost). The user Randi has a green line over her name which means that she's currently transmitting audio, i.e. other users in the channel are hearing her talking. The blackboard behind Randi's user-icon means that she sharing a desktop application which can be seen in the Desktops-tab.

Notice that Bjoern in the above screenshot has a red star. This means the user is administrator of the server. The user Randi has a yellow star which means she is operator of the channel and can thereby kick people out of the channel and modify the channel's settings. People who are operators are usually the users who created the channel.

The channels view only shows users in channels. To be able to see all users on the server it's possible to use the Online Users Dialog.

## Volume Controls

The volume controls are placed below the channels view. The first slider with a speaker to the left of it controls the master volume. Changing this increases or decreases the volume for all users. If you only want to change the volume of one person you can select this person and press Ctrl+Left arrow to lower volume and Ctrl+Right arrow to increase the volume. These two keyboard shortcuts are placed in the Advanced-menu.

The slider below the master volume with a microphone to the left controls your microphone's gain level, i.e. amplifying your volume so you become louder to other users.

To the right of master volume is progressbar with a wave to the left of it. This progressbar shows how much sound your microphone is picking up.

If voice activation is enabled the there will be a slider below the progressbar which sets the voice activation level. When using the voice activation slider to set the voice activation level ensure that it is not active all the time, since it can be annoying for other users. When voice activation becomes active the user in the channels view impersonating you will become green.

## Chat Tab

The Chat-tab is used for text chatting with the people in your channel. A screenshot is shown there:

The Chat-tab also maintains a list of events which occurred in your channel, like e.g. when a new user joins or leaves the channel. To send a text message to all users in your channel simply type in the line to the left of the Send-button. If the server supports channel commands it's also possible to send commands to the server using channel text messages.

## Video Tab

The Video-tab contains a grid of all the users who are currently transmitting video to the channel. The users who are transmitting video will have a blue frame around their user icon in the channels view as can be seen in the following screenshot:

The button with the '-' sign in the Video-tab can be used to remove users from the grid so you will no longer receive video data from that user.

Pressing the button with the '+' sign will add the user to the grid again.

The button with the two frames, one above the other, is for detaching a user from the grid so the user will be shown in a separate window.

The last button the Video-tab is for starting and stopping your video camera. If you want other users to also see video sent from you press the video camera in the toolbar to the right of the voice activation icon.

## Desktops Tab

The Desktops-tab contains a grid of shared desktop applications. Here is a screenshot of a shared desktop application:

Moving your mouse over the desktop window will show who owns the desktop. Press and hold the mouse to scroll the window if it's bigger than the Desktops tab. Check out the Desktop Share section on how to share a desktop application.

## Files Tab

If the server allows, users can upload and download files to and from a channel. When you join a channel you can see the files which are currently available in the Files-tab as shown in this screenshot:

Only users who have a user account on the server can upload files. Anyone can download files in a channel. Only the owner of a file, an administrator or an operator of a channel can delete a file. Instead of using the upload and download button in the Files-tab one can also drag/drop files from Windows' Explorer.

# Client-Menu

The Client-menu is used for connecting to TeamTalk servers and configuring the TeamTalk application.

Each of the menu items in the Client menu are described here:

- New Client Instance
  - Start a new TeamTalk instance, so you're able to connect to multiple servers. When starting a new instance you'll be asked to set up a profile. That way it's possible have use different configurations depending on which server you're connected to. There's a maximum of 16 profiles.

    - If you've received a .tt file from another TeamTalk user you can import the server to the Server List by pressing this button.
    - Other users can send you .tt files that have been generated to contain the information you need to join their server.

### Setup Encryption Dialog

TeamTalk Pro servers can enable encryption so all data sent and received cannot be decoded by anyone other than the client and server.

Using an encrypted connection is, however, not enough to ensure the server you're connecting to is authentic, i.e. someone else could intercept your initial connection and pretent to be running the server you're connecting to. This is known as a man-in-the-middle-attack. The way to avoid such abuse is to use certificates that verifies that the server you're connecting to is authentic.

To use certificates the owner of the TeamTalk Pro server must provide the client with a cerficate from a common/shared Certificate Authority (CA). This CA certificate can either be provided in a .tt file or in a *.cer file* (in PEM format).

To enable a CA certificate for a TeamTalk Pro server press the Open file button in the Certificate Authority (CA) row as shown below.

The CA certificate is valid if Issuer, Subject, Effective date and Expiration date are printed in the edit field.

Once a CA certificate has been set up the Verify server certificate checkbox is enabled and the client can now verify the connection will be establish only if the server is authentic.

Some TeamTalk Pro server owners may also want to verify that the clients who connect are also authentic. This is done by using Client certificate that has been issued by the TeamTalk Pro server owner along with a Client private key. The client certificate and private key can be provided in either a .tt file or in two .pem files (in PEM format).

Press the Open file button in Client certificate row and add the .pem file to enable a client certificate. If the client certificate is valid then Issuer, Subject, Effective date and Expiration date are printed in the edit field.

A Client private key file is required for a client certificate and this is added by pressing the Open file button in the Client private key row. If the private key is valid then the encryption algorithm is printed along with the key size.

Press OK to activate the encryption settings in remember to press Save to Server List in the Connect to a Server Dialog.

## Preferences Dialog

The Preferences dialog is used for configuring the TeamTalk application. Users should at least run through the General and Sound System-tabs to ensure everything is configured properly.

Please read section TeamTalk Preferences for a guide on how to configure TeamTalk.

## Sound Configuration-Menu

The Sound Configuration submenu is used for quick access to settings that are otherwise in Preferences Dialog's Sound System-tab.

Echo cancellation, automatic gain control and denoising can be enabled using shortcut keys. The currently active sound input devices and sound output devices can also be selected in Input Devices and Output Devices submenu.

Sound input devices with the [Loopback]] postfix sends audio played on the select input device back into TeamTalk as its microphone input.

## Record Conversations to Disk

Conversations with others users, both audio and text messages, can be stored to disk using the Record Conversations to Disk dialog in Client-menu or by pressing the recorder button in the toolbar.

The record conversations dialog looks as follows:

Each of the items in the dialog are explained here:

- Storage mode
  - Single audio file for all users
    - Audio from all users in your channel is merged into a single file.
  - Separate audio file for each user

The menu items in the menu group Me are options you want to perform on yourself. The possible options are shown here.

Each of the menu items in the Me-menu are described here:

- Change Nickname
  - This will change your name on the server. Your current nickname is the one shown in bold text in the channels view. The nickname is simply a display name. It has no relation to your username (if you have a user account). In User Accounts Dialog it's possible to lock the nickname so it cannot be changed. This is especially useful if you use BearWare.dk Web Login and want people to use their registered name.
- Change Status
  - This is used to change your status mode, like e.g. Available, Away, Question-mode and set a message regarding your current status.
- Hear myself
  - When in a channel this option can be used to hear your self to e.g. determine your voice level. This is actually the same as subscribing to your own voice stream in [Subscription-menu](Subscriptions-Menu).
- Enable Push To Talk
  - Push To Talk is a key combination you need to hold down whenever you are talking. Using a Push To Talk key combination is especially usefull if you are using speakers and have problems with echos. To transmit voice data from microphone requires the User Right User can transmit voice data.
- Enable Voice Activation
  - Instead of using Push To Talk one can have TeamTalk detect when you are talking and then start transmitting. To transmit voice data from microphone requires the User Right User can transmit voice data.
- Enable Video Transmission
  - Enable this item to start transmitting video to other users in your channel. Note that you need to configure your web camera before doing this. To transmit video data from webcam requires the User Right User can transmit video data.
- Enable Desktop Sharing
  - Share an application on your desktop with other users in your channel. This can e.g. be used for doing a presentation. See the Desktop Sharing dialog for more information. To transmit shared desktops requires the User Right User can transmit desktop sessions.
- Notifications
  - Sub menu items to enable/disable [Sound Events](Sound Events) and Text to Speech.

## Enable Push To Talk Dialog

Using Push To Talk is a good way to ensure people do not overlap each other when they are talking and to avoid echos from speakers. To set up a hotkey simply hold down the keys you want to use as your key combination and release them all again. The Push To Talk dialog will show the keys you're holding down like here.

Using Ctrl is a good choice for a Push To Talk key. Note that using regular keys can make Windows beep unlike when using non-modifier keys like Ctrl, Alt, Shift. Therefore Ctrl or Alt or Shift is recommended.

## Enable Desktop Sharing Dialog

The window of an application on your desktop can be shared with other users in the same channel. This can be used for doing a presentation in an eLearning scenario.

The Desktop Sharing dialog is shown here:

To be able to share a desktop window requires the User Right User can transmit desktop sessions.

Each of the items in the dialog are explained here:

- Share entire desktop
  - Instead of sharing only one application you can share your entire desktop. Note that this may require a lot of bandwidth usage.
- Share active window
  - Share the window on your desktop which currently have keyboard and mouse focus. This option is useful if you intend to show several application windows during your presentation.
- Share specific window
  - Only share a single application window and it has to be the one with the title specified in the selection box.
- Color mode
  - The more colors you use for showing your application the better it looks, but it also requires mode bandwidth.
- Update interval
  - Enable this option if the window you're sharing changes during your presentation. TeamTalk will then update the window on a timely basis.
- Share desktop cursor
  - Enable this option if remote users should be able to see where your mouse cursor is point to.

# Users-Menu

The menu items in the Users-menu are used for changing the settings of other users and interacting with them. The Users-menu is shown here:

Each of the menu items in the Users menu are described here. A user has to be selected in the channels view for the Users menu items to be active.

- Allow Desktop Access
  - If you're sharing a desktop window using desktop sharing then you can allow the users you select in the channel view to control mouse and keyboard on your computer by enabling this menu item. Note that Allow Desktop Access is actually the same as enabling the Desktop Access-subscription in Subscription-menu.
- Op
  - Op is short for channel-operator. Read section Channel Operators to learn more about channel operators.
- Volume
  - If a user is either too loud or too quiet one can use the volume dialog to turn the volume up and down. Most users would probably prefer to use the volume controls in the Advanced-menu.

## Channel Operators

A channel operator is typically a channel owner, i.e. the user who initially created the channel. As channel operator one can kick people out of the channel, make changes to the channel's properties and control who can transmit in the channel.

Being channel operator is similar to having the User Right User can create/modify all channels but instead of "all channels" the user can only make changes to the channels which the user is operator of.

When creating a channel one can also set an Operator password so others can become channel-operators by entering this password.

In the User Accounts Dialog it's possible to set up users to automatically become channel operators.

As channel operator use the Transmit Control to toggle who can transmit to the channel.

## Subscriptions-Menu

Subscriptions are used for ignoring certain data or events from a user. If e.g. you do not want to receive text messages from a certain user you can tell the server that you want to unsubscribe text messages from that user.

## Create Channel Dialog

To chat with other users in TeamTalk one has to either create a channel or join an existing channel. A new channel can be created by pressing F7 and the following dialog will show up:

Each of the fields in the create channel dialog are described here:

- Channel Path
  - Each channel can have subchannels which again can have subchannels. In TeamTalk channels are separated with / and the full path of your new channel will be displayed here.
- Channel name
  - The name of your new channel. Ensure that / is not in the name.
- Topic
  - Each channel can have a topic which both users who are in the channel and who are not in the channel can read.
- Password
  - The password required to join the channel (optional).
- Operator password
  - The first person to create a new channel will automatically become operator of that channel. This means the user can kick people out of the channel and update its settings later on. If the person leaves the channel at some point and comes back that person can click the Op item in the Users-menu to become operator again.
- Max users
  - The maximum number of users allowed in the channel.
- Disk quota (KBytes)
  - The maximum number of KBytes available for file storage in the channel when uploading files. This field can only be modified if user has User Right User can create/modify all channels. The default Disk Quota is set up when configuring the TeamTalk server.
- Permanent channel (stored on server)
  - Only users with User Right User can create/modify all channels can create permanent channels.
- No interruptions (no simultaneous voice transmission)
  - If this option is enabled only one person can talk in the channel. In other words where will be no overlapping conversations. To talk in this type of channel you must wait until the channel becomes "silent". In Sound Events in Preferences there's an option to play a sound when a channel is "free for chat".
- Classroom (operator-controlled transmission)
  - If this option is enabled the channel operator can control who is allowed to talk, send video and share desktops in the channel. See section classroom for more information.
- Operator receive only (only operator see and hear users)
  - This channel type can be used for reducing network traffic when e.g. TeamTalk is used for teaching. Only user's with User Right User can create/modify all channels and operators of a channel will see and hear users in the channel.
- No voice activation (only Push-To-Talk allowed)
  - Enable this channel type to disallow voice activation
- No audio recording allowed (save to disk not allowed)
  - Don't allow users to use the Record Conversations to Disk option.
- Hidden channel
  - Create a hidden channel that can only be seen by users with User Right User can see hidden channels. Creating a hidden channel requires User Right User can create/modify all channels. To join a hidden channel that cannot be seen use the Create Channel Dialog and type the name of the channel, its password and press OK. Ensure to be in the parent channel of the hidden channel while doing this.
  - A hidden channel must be a sub channel with no other sub channels, i.e. a leaf node.
  - Note that it is not possible to update an existing channel to a hidden channel, and vice versa.
- Audio Codec
  - Codec Type
    - In TeamTalk each channel must specify which audio codec all users in the channel must use to join the channel. TeamTalk currently supports Speex and OPUS.
  - OPUS codec
    - Application
      - Use VoIP if channel is primarily used for users talking together. Use Music if channel is primarily used for streaming high quality audio, like e.g. music.
    - Sample Rate
      - The sample rate to use. The higher the better audio quality.
    - Audio Channels
      - Mono or Stereo. OPUS automatically switches to mono if bitrate is less than 30 kbit.
    - Bitrate
      - The bitrate to use. OPUS supports 6-510 KBit/sec.
    - Variable Bitrate
      - Enable to reduce bandwidth usage.
    - Ignore silence (DTX)
      - Discontinuous transmission (DTX), i.e. if the OPUS codec detects there's silence then it will output empty packets to conserve bandwidth.
    - Transmit interval
      - The number of milliseconds of recorded audio before the TeamTalk client should transmit. If transmit interval is higher than 120 msec then a Frame size must be specified.
    - Frame size
      - A higher frame size gives less bandwidth usage but more latency. If transmit interval is higher than 120 msec then a frame size must be specified.
  - Speex codec
    - Sample rate
      - The sample rate to use. The higher the better audio quality.
    - Quality
      - Increasing the quality will require more bandwidth but the sound quality will get better. Ensure to use a setting which is not higher than everyone you want to talk to have an Internet connection which supports the required bandwidth.
    - Transmit interval
      - The number of milliseconds of recorded audio before the TeamTalk client should transmit.
  - Speex Variable Bitrate
    - Sample rate
      - The sample rate to use. The higher the better audio quality.
    - Quality
      - Increasing the quality will require more bandwidth but the sound quality will get better. Ensure to use a setting which is not higher than everyone you want to talk to have an Internet connection which supports the required bandwidth.
    - Max bitrate
      - The encoder should stay below this bitrate.
    - Ignore silence (DTX)
      - Discontinuous transmission (DTX), i.e. if the OPUS codec detects there's silence then it will output empty packets to conserve bandwidth.
    - Transmit interval
      - The number of milliseconds of recorded audio before the TeamTalk client should transmit.
- Audio Configuration
  - Enable fixed audio volume for all users
    - In most cases users have microphones with different audio volume levels which makes some users louder than others. Enabling this option ensures that all users in the channel speaks at the same audio volume level. Note that this option may reduce audio quality.
  - Volume level
    - The reference volume all users in the channel should use.
- Stream Timeout Timer
  - Voice stream max duration
    - The maximum time a user can transmit voice to a channel without toggling the Push-to-Talk button or retrigger voice activation.
    - This feature is especially useful when using channel type No interruptions because no one is then able to block the transmission queue for an indefinite amount of time.
  - Media file stream max duration
    - The maximum time a user can stream a media file to a channel without starting a new media file.

## Classroom Channel Type

If there's many people in a channel it's often nescessary for someone to control who is talking. The classroom channel type can be used for controlling which users are allowed to transmit audio, video and media files to a channel.

If a channel is configured as a classroom then the channels view will look something like this:

The checkboxes in front of each user are used to control who can transmit to the channel. In the above screenshot Ida and Liv are e.g. allowed to transmit video from webcams. The user Randi is allowed to transmit shared desktop but cannot transmit video since she is not checked.

As can be seen on the screenshot there's also checkboxes to the right of the channel name Room 11B. These checkboxes can be used as a shortcut for allowing everyone to transmit. So voice and media files can be transmitted by anyone in the channel.

As an alternative to the checkboxes it's also possible to use the Transmit Control menu to toggle who can transmit.

For a non-operator of the classroom channel the view of the Room 11B channel will look like this:

A non-operator cannot modify any of the transmission settings. They will have to ask the channel-operator to toggle the checkboxes for transmission.

## Stream Media File to Channel Dialog

In the Channels-menu there's an option to stream media files to others users in the same channel. For fast access the play icon in the toolbar can also be used.

Here's an example of streaming a media file with video content to a channel:

The users receiving the media stream can use the volume dialog in Users-menu to control the volume level of the media file. If it's media file containing video content then the video can be seen in the video-tab.

# Server-Menu

The Server-menu is mainly intended for server administrators to administrate users who have access to the server. The Server-menu contains the items shown here:

Each of the menu items in the Server-menu are described here.

  - List all the users who are banned from the server. Users are banned based on their IP-address. Since user's IP-addresses often change from day to day it might be that a user who was previously banned can log on to the server again a day or two later. Only users with User Right User can ban users from server can list the banned users on a server. More is explained in section Banned Users Dialog.
- Online Users
  - List all users who are currently connected to the server, also those who are not in a channel.
