The quick infos and context-related information are displayed for the contact person who is currently calling. In the case of two or more parallel connections, the information is displayed for the contact who is on the active line at the time. If you switch to a connection on hold, and activate the line you choose, the display of contact details is updated accordingly.

For further information on how to switch between active connections and those on hold, please refer to 5.6 Switching between several subscribers.
