I have been successful in adding this information into manager.conf
tlsenable = yes
tlsbindport = 5039
tlsbindaddr = 0.0.0.0
tlscertfile = /var/lib/asterisk/keys/xxxx.pem
tlsprivatekey = /var/lib/asterisk/keys/xxxxx.pem
Now I need to know if there are any other steps to enable it and/or how to test it to be sure it’s working. I used Blink to test the Sip over TLS
Any helpful tidbits would be appreciated.
