Configuring Eventlist BLF
Grandstream GRP261X Carrier-Grade 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. GRP26XX 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.
