Want to have the 3rd-party CC interface more secure, rather than passing username/password in clear text. I hunted a bit for any work in this area, didn’t see it. Does anyone know of such work in progress?
As far as I know the Manager API interface will remain a plain text telnet/tcp interface. If you want something encrypted, the best way to go would be to write a proxy, where on your Asterisk box you have the Manager API and the proxy, then the proxy serves a TLS connection elsewhere.
