I am trying find out if anyone has successfully (without the creation of a blacklist) blocked these spam calls. I opened a support ticket with Palo Alto and they suggested that I reach out to this board for help.
We are constantly getting our conference systems coming off sleep mode to respond to the calls.
There are few articles floading around the web in regards to this issues like the link below
I am sure this issue can be mitigated by a custom profile or signature.
Attached is a PCAP output from one of the packets. I am guessing if a custom signature can match a pattern in the PCAP output, we can block these annoying calls.
