What you can do to deactivate TLS1.2 and activate TLS1.1 is auto provisioning:
static.security.default_ssl_method = 4
This configures the TLS version to use for handshake negotiation between the phone and server (for example, SIP registration server, provisioning server)

Hope this will help.

Thanks for your reply! In the meantime i stumbled across another thread mentioning this option. I had already tried - but without success. Seems like the TAPI driver is not compatible with HTTPS at all and not "only faulty" due to the mentioned TLS bug. Sad

So only chance seems to be to disable HTTP -> HTTPS redirection in phone webserver. But I think such feature has to be added from Yealink development team. Maybe they can add a checkbox in EWS to enable / disable this

Then try:
static.wui.https_enable = 0
(Network > Advanced > Web Server > HTTPS)
This disables to access the web user interface of the phone over a secure tunnel (HTTPS)

Kind regards,
Frank.
