I have a v15.5 SP6 PBX (hosted in datacenter) and phones connect to it by STUN. Has been working for more than a year without problems. We have not made any changes in server, network or phones for weeks now.
Since this week all users report their BLF is not working anymore. I had a look in the activity log and it is flooded with these messages:

What is happening here?
