BLF Light stuck on busy for select users

[papergavin]

Hi Folks,

I deployed about 17 voip phones for a company. All provisioned and set up the same. There is about 4/5 users whos blf light is always busy even if they aren't on a call. They can still receive transfers/calls, but the users are never truly sure if they are on the phone or not.

I tried to factory reset them, but they all just immediately went back to "busy".

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.
