Freepbx sending packets like crazy

Using FreePBX 13.0.196.2… I noticed that freepbx is sending non-stop packets to one of my yealink t48g phones. The phone is doing nothing. It’s on hook. Not sure how to figure out that is going on. Here is a sample packet capture. The system and phone is working fine otherwise. I have 10’s of these t48g’s and this is the only one doing it. Can anyone tell me what is happening?

(edit - even with the phone powered off freepbx is still sending packets non-stop to it’s ip address)

(edit2 - I ran lsof on that port and here is what I get…)
