A few of the phones are remote phones that we have an OpenVPN certificate applied to. The VPN certificates we're using are RSA-SHA1 which is a weak digest/algorithm and no longer supported on our firewalls. Since upgrading the firewalls and creating new certificates for SHA-256, the phones no longer work. Are these phones only compatible with RSA-SHA1?

Hi,

Please correct me if I'm wrong, but as far as I know, the phone supports AES 256 and not SHA 256.

I'm referring Auth digest algorithm. I found some documentation on Yealink's site and noticed it says IP Phones support MD5 and SHA1 signature algorithms.

Kind regards,
