T4x: Possible to deactivate TLS 1.2 / disable HTTP redirection?
Greetings community!

We are using the PhoneSuite CTI Software with Yealink phones - the TAPI Driver of this Software is connecting to the phone using IExplore core component. This was working fine some Firmware versions ago. After recently updating to the TAPI Driver throws "HTTPS/SSL error" - This is caused due to a bug / incompatibility in IE with SSL2 in conjunction with TLS1.2 preventing successful connection to the phone. Workaround would be, to deactivate HTTPS function in Yealink phone completely. We would prefer, to not do this "workaround". We would rather like to just deactivate TLS 1.2 in phone config and fall back to TLS1.1. Is there a way to do this? Other solution would be, to disable HTTP redirection in phones webserver. TAPI Driver is only functioning properly with HTTP - but phone is forcing HTTP requests to be redirected to HTTPS in recent FW causing the mentioned bug above.

Are there any other solutions than "disable HTTPS" right now?

Thanks in advance!
