# Working with the address book
The TrueConf Group terminal supports the use of an address book for easy calling. It allows for the division of the contact list into groups and a shared address space with TrueConf Server, TrueConf MCU, and H.350 LDAP.
# Sections of the address book
To configure the contact list on the main screen, select Contacts or press the
button on the control panel.

The address book can have multiple lists of users:
Favorites – these are contacts added locally and marked with the corresponding
button in the contact editing window;History - call history of the terminal, where you can find contacts of any of the types described below;
Local contacts – the local list stored on the endpoint
NDI – NDI streams available on the local network are automatically discovered in the background;
TrueConf MCU – contacts imported from TrueConf MCU during integration with it;
LDAP – with integration with the LDAP service;
TrueConf Server – contacts from TrueConf Server when integrated with it;
TrueConf Group – other TrueConf Group endpoints available on the local network. When this option is selected, they are automatically searched. The endpoint name is set by the administrator in the field .
# How to change the view and call a user
Any list can be shared (default view), and in addition, the tab supports grouping. To switch to group view, click Groups under the search field. To switch back to the shared list, click the same button. You can navigate to contacts in any group by pressing the OK button.
To call a subscriber, select them from the appropriate list (and group, if necessary) and press
or the call button
on the remote control. If there are many users in the list, start typing the desired name at the top, and the list will automatically filter. When making a call, the port for each protocol is automatically added if it has not been explicitly specified in the dial string.
# Edit the list
In the local address list, one can add a new contact or edit the contact that had been saved previously.

To edit, click the corresponding button after selecting a subscriber. The contact card will open:

You can change its name; specify SIP, H.323, RTSP, VNC, or NDI address; and set a bitrate limit for communication with it. You can specify up to 5 addresses for each contact, and protocols can be repeated. Any address can be marked by clicking the
button, making it the priority when calling the user.
To add a new contact to the list, click on the Add new entry button which is under the search field.
# Call History
In the Call history section, a list of completed calls is displayed, showing:
Username
call information: incoming
, outgoing
, missed
, as well as the call status:Canceled – you declined the outgoing call before the recipient accepted it.
Decline – the subscriber you called has declined the call;
Disconnect – the call was successful, and the participant has disconnected from the call;
Missed – you did not answer the incoming call within the allocated time;
Busy – during an outgoing call, the subscriber is already on another call;
Doesn't answer – during an outgoing call, the recipient did not answer within the allotted time;
Unknown – an error occurred during the outgoing call, and the call could not reach the subscriber.
Time (for today's calls) and date (for earlier calls).
To call a contact, select them from the list and press
or the call button
on the remote control.
You can attach a subscriber's address from the history to a contact in the local address book by clicking the Add to contact button and selecting the desired item from the list. If the subscriber is not among the local contacts, you can add them by clicking Create.
