ABSTRACT:
A switching system in which telecommunications features are improved by the use of the proximity status of a telephone station set user. The status is transmitted to the switching system over the same telephone line used for the station set. The proximity status information simply defines the presence or absence of a person to answer calls to the station set without identifying a particular person.
