# Working with the address book
The TrueConf Group terminal supports working with an address book for convenient calling. It also supports dividing the list into groups and integration with TrueConf Server, TrueConf MCU, Email, and LDAP.
# Address Book Sections
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 – contacts added locally and marked with the
button in the contact editing window;
History – call history of the terminal, displaying contacts of any type described below;
Local contacts – the local list stored on the endpoint
NDI – NDI streams available in the local network (the streams are searched for automatically when they are selected)
TrueConf MCU – the contacts imported when running the endpoint in integration with TrueConf MCU
LDAP – when integrating with the LDAP service;
TrueConf Server – contacts from TrueConf Server when integrated with it;
TrueConf Group – other TrueConf Group terminals available on the local network. When this option is selected, they are automatically searched. The terminal name is set by the administrator in the field.
# How to change the view and call a user
Any list, except for TrueConf Group and NDI, can be general (default view) or grouped. To switch to the grouped view, click Groups below the search field. To switch back to the general list, click the same button. You can access contacts in any group by pressing the OK button.
To call a subscriber, select them from the desired list (and group, if necessary) and click or the call button
on the remote control. If the list contains many users, start typing the name of the desired user at the top, and the list will automatically be filtered. When making a call, the port for each protocol is added automatically unless it was explicitly specified in the call line.
# 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, press the corresponding button after selecting a subscriber. The contact card will open:

You can change its name, specify a SIP, H.323, RTSP, VNC, or NDI address, and set a bitrate limit when communicating with it. Each contact can have up to 5 addresses specified, and protocols can be repeated. Any of the addresses 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, indicating:
Username
call details: incoming
, outgoing
, missed
, and the call status:
- Canceled
- Decline
- Disconnect
- Doesn't answer
- Unknown
Time (for today's calls) and date (for earlier calls).
To call a subscriber, select them from the list and click 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.
