I have a customer with some Cisco ip phones that's are currently registered and in use with an asterisk PBX server.
I am wondering if there is a way to enable tls and/or srtp on these phones to use connected to an asterisk machine.
My current thinking is that they do support it, however it may be difficult to generate the ctl file that may be needed to create the trust with the asterisk server.
Can anyone provide any insight here?
