Hello,
My company offers SIP services over the public internet and I was ask if there are any best practices to make the network more secure.
Apart from using TLS authentication in SIP, is there any way for the firewall to inspect SIP in L7? I am referring to a traditional firewall and not a NGFW.
The current policy is to allow from all on the SIP ports (5060-1 and some random high ports).
