Configuring Eventlist BLF
Grandstream GXP2130/2140/2160/2170/2135 Enterprise IP Phones support both Grandstream UCM Busy
Lamp Filed and Event List BLF features and allows end users, such as attendant, to monitor the call status
of users in the list. GXP2130/2140/2160/2170/2135 supports this feature by sending out the subscription
request to the UCM and changing the indicator status of the Line keys, MPKs, or virtual MPKs that
associated with the monitored users. Additionally, the phone is also able to display the original caller’s call
ID and to pick up the calls to the monitored extensions by using a pre-defined feature code called BLF-
Call-pickup Prefix.
