# Integration with services
TrueConf Group supports integration with various services and provides additional features when connecting to other TrueConf solutions.
In the Settings section of the control panel, one can check when the endpoint was last synchronized with a third-party service. Besides, there is the button for forcefully updating data.
In addition to LDAP integration, discussed in the section "Working with the address book", the following options are also available.
Integration with a mail service makes it possible for TrueConf Group to receive invitations to the conferences scheduled on TrueConf Server and display them in the calendar on the device screen.
At first, it is necessary to configure the reception of invitation emails:
Use the remote control to go to the Configuration → Services → EMAIL section.
In Enable, choose On.
Enter the following information in the mail service connection fields:
Email box address to which conference invitations will be directed
Mail service address
Username (login) and password for the email box
The protocol used for receiving the invitation emails from the mail service (additional configurations may be needed on the side of the mail service)
The time interval for checking if new email invitations have been received.
When the first invitation is successfully received from the mailbox, you will see the list of upcoming meetings in the TrueConf Group calendar.
# TrueConf MCU
Integration with the mixing video conferencing server TrueConf MCU makes it possible to import the list of MCU contacts to the address book of TrueConf Group.
To do it:
Use the remote control to access the Configuration → Services → TrueConf MCU section.
In Enable, choose On.
Specify the following information in TrueConf MCU connection fields:
Its address (IP or domain name)
Administrator login and password needed for connecting from the endpoint and downloading the address book.
4. To apply changes click Update address book.
If synchronization is disabled, the contacts imported from TrueConf MCU will be deleted from the endpoint address book. To bring them back, one should enable synchronization again, and update the address book.
# TrueConf Server
If integration with TrueConf Server is enabled, you can import the contacts of the specified server user to the TrueConf Group address book.
Go to Configuration → Services → TrueConf Server section.
