3CXPhone for Windows (16.3.0.264) and Yealink (96.87.0.16) no CTI

[Arthur.b]

Hi,

Since the release of the new firmware for the Yealink T5X (96.87.0.16), the CTI functionality via the "3CXPhone for Windows (16.3.0.264)" client no longer works. When dialing and clicking the green button to initiate the call, nothing happens.

3CX is running V20 U5.

Many customers are forced to use version 16 of the client to benefit from TAPI integration or CRM client intégration.
And they cannot download the new version of the client because the Microsoft store is unavailable.

Thank you for your help !

The new 3CX softphone has the CRM and TAPI capabilities



You can deploy the 3CX application through Intune, Group Policy etc by getting the .MSIX file from the download page of the 3CX Customer or Partner portal.

Thank you Nicholas for this quick answer !
I'll forward to our customer.

And do you know why it no longer works ? it's about the TLS 1.1 and TLS 1.2 that is not supported anymore on that new firmware ?
