What is the remote endpoint? The message itself is occurring because we are receiving encrypted traffic and failing to decrypt. I've seen this in recent times but it's been because of the remote endpoint and not Asterisk itself. Since it's encrypted and visibility into things isn't great, it's hard to point to precisely what is going on though. -- Joshua C.
