I’m trying to setup secure (encrypted) communication with Twilio as my SIP trunk provider.
Their instructions for setting up freePBX start by downloading a .pem file to be installed in /etc/asterisk/keys
Their instructions then seem to assume the existence of an asterisk.pem file and a asterisk.key file from that directory. There aren’t any such files in that directory. And a .pem file by itself does.'t appear to be an installable certificate.
How do I proceed?
