A telecommunications system comprising:
- a first base;
- a second base;
- a first plurality of handsets, wherein each handset of the first plurality of handsets is localized to the base;
- a second plurality of handsets, wherein each handset of the second plurality of handsets is localized to the second base;
- and
- a status database for storing a status information of a first handset of the first plurality of handsets,
- wherein the first base broadcasts to the first plurality of handsets a status broadcast that comprises the status information and enables a busy monitoring capability of a second handset of the first plurality of handsets to monitor the status information of the first handset, and the second base broadcasts the status broadcast to the second plurality of handsets, and
- wherein:
- the status database also stores a shared-line status of a line shared among at least two shared-line handsets;
- and
- the status broadcast comprises the shared-line status and enables a key line emulation capability of a shared-line handset to monitor the shared-line status of the shared line.
