Blf stays red

[rubberducky]

I'm using yealink t27g on a multi tenant system. One client mentioned that all extensions show the receptionists extension being red. Then, within 3 days, I had four other clients with the same issue.

What should I be investigating?
Also, anyone know a good rum? I like to sip while I troubleshoot sip.

Seems to me like a firewall issue.
It is likely the PBX is trying to updates the phones, but the message can't get through.
Check sngrep as you might see the messages failing to be delivered.

First step is to have the phone rebooted. I've done that and heard no more complaints before.

Next, maybe change the mode of delivery by changing the Keep Alive Type.

No, this absolutely shouldn't be the case otherwise they couldn't make and receive calls normally.

Look in the following file

/etc/freeswitch/autoload_configs/lua.conf.xml

Down at the bottom you will see a number of options commented out, blf subscribe etc.

Uncomment what you need and restart freeswitch.

<!-- FusionPBX: Support BLF for call flow -->
    <!-- There 2 way to handle this
      1 - Monitor - ignore SUBSCRIBE and just send NOTIFY each X seconds
      2 - Event handler - handle each SUBSCRIBE request
    -->
    <param name="startup-script" value="call_flow_subscribe.lua"/>
    <!--<param name="startup-script" value="call_flow_monitor.lua"/>-->

At the risk of asking a stupid question, I see there are the two methods. Do I need to disable one when I enable the other?
