Configuring BLF on Polycom phones

BLFBusy Lamp Field - A set of indicators that monitor the current state (online, offline, busy, on a call) of a phone extension. (Busy Lamp FieldA set of indicators that monitor the current state (online, offline, busy, on a call) of a phone extension.) is a light placed on a telephone device. BLF notifies you if another extension is busy or not.

Setting BLF on Polycom telephones is not as easy as on other telephones. You need to prepare a configuration file and upload it to Kerio Operator.

Preparing a configuration file

Prepare a file with the following content:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><attendant attendant.resourceList.1.address="sip:10@192.168.12.91" attendant.resourceList.1.label="Ten" attendant.resourceList.2.address="sip:11@192.168.12.91" attendant.resourceList.2.label="Eleven"/> <call call.directedCallPickupMethod="legacy" call.directedCallPickupString="*8"/>

This example file enables two BLF buttons. Button one monitors extension 10 on Kerio Operator with IP address 192.168.12.91. This button is labeled Ten. A second button monitors extension 11 on same Kerio Operator and has label Eleven. Call pickup PBX service is set to *8.

Upload the file to /var/tftp/polycom-0004f223510b-manual.cfg where 0004f223510b is a phone hardware (MAC) address.

Uploading the configuration file to Kerio Operator
