Hello,

on every installation of Operator I have these errors in warning logs:

Everything Works, so this is not something that causes any complications, but it's really annoying anf Google didn't help much.
Anybody has an idea what is the cause of this ?

Hi,

these warnings are mostly caused by botnets attacking SIP. They send an INVITE packet to Operator, Operator replies Unauthorized and the bot fails to respond. Operator retransmits the reply several times before giving up and logging the warning.
