Hot Desking
Hot desking originates from the definition of being the temporary physical occupant of a work
station or surface by a particular employee. A primary motivation for hot desking is cost
reduction. This feature is regularly used in places where not all the employees are in the office at
the same time, or not in the office for very long, which means that actual personal offices would
be often vacant, consuming valuable space and resources.
You can use hot desking on the SIP-T48S IP phone to log out of existing accounts and then log
into a new account. As a result, many users can share the phone resource at different times. To
use this feature, you need to configure a hot desking key in advance.
Note
To configure a hot desking key via phone user interface:
1. Tap More.
2. Tap the desired line key.
3. Tap the gray box of the Type field, and then select Key Event from the pull-down list.
4. Tap the gray box of the Key Type field, and then select Hot Desking from the pull-down
list.
5. (Optional.) Enter the string that will appear on the touch screen in the Label field.
6. Tap the Save soft key to accept the change or to cancel.
Hot desking key is configurable via web user interface at the path Dsskey->Line Key.
Hot desking is not available on all servers. Contact your system administrator for more
information.
