Hello Team,

Please find the temporary fix for the 3 CX web client call control issue.
We can share this with our Customers until the new EPOS Connect is released, September 3rd 2020.

There is a setting in Chrome, if we change that it will still work with our existing software.

@Nusan Dubey<mailto:[email-masked]> lets align on Monday so we can add this as a public FAQ in our knowledge base so we can only send the link to our Customers.

Step 1:
Open chrome and go to chrome://flags/

Step 2: Search for “tls”, you will find “Enforce deprecation of legacy TLS versions”

Step 3: Set the Default to Disable and Relaunch browser

Now you will be able to connect to Web-socket.

Best regards,
Filip Trajkov
