Busy Lamp Field for Trunks
On SIP extensions, NAVAN supports the Busy Lamp Field (BLF) Subscription feature for Trunks, enabling SIP extension
users to monitor the status of desired trunks.
Using BLF, SIP extension users can monitor the status of different Trunk types, namely CO, Mobile and SIP.
To provide this feature to SIP extension users, you must enable this feature on their SIP phones and configure the trunk to
be monitored on the BLF key of their SIP phones. The number of trunks that can be monitored will depend on the number
of BLF keys supported on the SIP Phones.
With BLF subscription and BLF key configured, whenever, there is a change in the state of the monitored trunk,
NAVAN sends a NOTIFY message to the SIP Extension. The NOTIFY message contains the Call State. On
receiving the NOTIFY message, the SIP Extension updates the LED indication of the BLF key on the SIP phone.
The SIP extensions will indicate the following calls states for the outgoing and incoming calls on the monitored
trunks:
SIP phones may differ in the BLF indication (LED color and cadence, text message display) they provide
for the Call States. Refer to the manufacturer’s documentation for BLF Indication supported on the SIP
phones.
How it works
•
An Open Standard SIP Phone is registered as a SIP Extension, with the extension number 3301.
•
As the user of extension 3301 wants to monitor the trunk CO-001, BLF subscription is enabled on
extension 3301 and CO-001 is assigned to the BLF key on the SIP phone.
