Afterwards, the network generates a NOTIFY request on any registration
update for the supervised PUI. The registration states are « Registered »
and « Unregistered » . The service variable for DND supervision will be
discussed in next section.
Upon reception of a NOTIFY request, TB30 update the lamp associated to the
supervised phone accordingly.
Implementation and configuration
Table below describes an overall TB30‟s behavior that is used for
implementation, based on the Dialog and Registration and DND
supervision of a same target:
If user presses the function Key:
BLF Key is pressed in OFF state --> phone initiates a call toward the
supervised SIP-URI
BLF Key is pressed in STEADY ON state --> phone initiates a call toward
the supervised SIP-URI
BLF Key is pressed in BLINKING SLOW state --> NO action is taken
BLF Key is pressed in BLINKING FAST (supervised phone is ringing)
state --> phone launches a call Pickup of the supervised phone
Call pickup is launched by initiating a call toward a service code that includes
the number to pickup. It can work with Soft Key or with Function key (user
orientated BLF)
For call pick up service, please refer to “TB30 SIP New Features SG vx.62 P.
145 How to activate call Pick-up Service.
Remark:
If the status of the phone is in ringing, in communication and all others,
except idle, function key should remain inactive if the user presses them.
But, the supervision (LED blinking or other, including state change) should
remain active during call.
