Is anyone currently using s705 endpoints on Freepbx 17 with Openvpn via EPM?
My conclusion is that Openvpn v2.6.3 simply can not be forced to use TLSv1, cipher TLSv1/SSLv3 ECDHE-RSA-AES256-SHA, 2048 bit RSA.
Sangoma claims the s705 phone supports TLS v1.2. but I can not force the phone to connect any higher using the ovpn file manually or with EPM. Does anyone have insights on the client side openvpn version and what it actually supports?
Yea this is unfortunate they didn’t push one last firmware update for the S series phones with a newer version of openvpn before the eol. The only conclusion is to run a standalone openvpn server that supports the 2.2v the endpoints are using. Cumbersome but do-able. Support naturally advised against downgrading the server side. You can not from what i’ve dug through and tried set explicit configs on the newer server version to work with the 2.2v endpoints. Ive exhausted all options and simply swapped my endpoint with a P series phone for now. Good Luck All!
