Sounds like a problem on the PBX side. For clarification, BLFs do not monitor other phones directly; all they do is ask the pbx to send messages indicating what state other phones/devices/etc are in (i.e. ringing, unavailable/busy, idle, etc). The PBX does the actual heavy lifting to keep track of what phones are doing and send out the BLF notifications as needed.

If you do a packet trace or capture you should see the phone conversing with the PBX, and getting replies in the from of SIP Notification packets.
