VC400/VC120 system can display: local contacts, Yealink Cloud contacts and YMS contacts.
 Local contacts: The VC400 system can store up to 500 local contacts and 100 conference
contacts. The VC120 system can store up to 500 local contacts, and does not support
conference contacts.
You can add multiple numbers for a local contact (at most 3). A conference contact
consists of one or more local contacts (at least 1, at most 3). You can establish a conference
call quickly by calling conference contacts.
You can import or export local contact list to different systems to share the local directory.
The system only supports the XML and CSV format contact lists. You can view local
directory via web user interface, remote control and the video conferencing phone. But
you can edit or delete the local directory via web user interface and remote control.
 Yealink Cloud contacts: If you log into the Yealink VC Cloud Management Service
platform, Yealink Cloud contacts which are created by your administrator, appear in your
directory. Note that only the administrator can add, edit and delete Yealink Cloud contacts
on the Yealink VC Cloud management service. On your VC400&VC120, you can only search
for and place calls to the Yealink Cloud contacts. For more information on Yealink VC
Cloud management service, refer to Yealink VC Cloud Management Service Administrator
Guide .
 YMS contacts: If you log into the Yealink Meeting Server, enterprise directory which is
created by your administrator, appears in your directory. Note that only the administrator
can add, edit and delete the YMS contacts and permanent VMR on the Yealink Meeting
Server (YMS). The administrator can also determine whether synchronize the permanent
VMR to the VC400&VC120. On your VC400&VC120, you can only search for and place calls
