from any state => terminated
from any state => trying
from any state => early
from any state => confirmed

D8XX_BLF-XML_FR-2

On D8xx IP phones, any PFK (programmable function key - physical or virtual) can be assigned to a function, which allows monitoring state changes of the configured SIP extension (UAS) on another IP phone. This function shall be called "BLF-XML". The following states of the monitored SIP extension (UAS) shall be processed:

UAS state	Dialog state (NOTIFY)	Processed state
idle mode	terminated	idle
line seizing	trying	dialling
incoming call ringing	early	ringing
incoming call accepted outgoing call accepted	confirmed	talking

Must Have

Fully implemented

3

D8XX_BLF-XML_FR-3

The assignment shall be configured either manually via web user interface (WUI) and/or phone user interface (PUI), and automatically via auto-provisioning (HTTP/TFTP setting server), SRAPS, or remote management (TR-069).

Must Have

Fully implemented

D8XX_BLF-XML_FR-1-1

On D8xx series, during an active subscription, state changes of the monitored SIP extension shall be visualized on both, PFK LED and PFK label.

Must Have

Fully implemented

The PFK LED behaviour and colour shall be according to this table

Dialog state	terminated	trying	early	confirmed
LED behaviour	off	on	blinking	on
LED colour	-	red	red	red
