1. Go to Dashboard > Updates and perform updates.
2. You will see Phone Templates update for Snom (Look screenshot)
3. Select and download
4. Then go to Settings > Templates and from the drop down list select Snom template.
5. On the top of the XML template make sure that the Version is 68850:
<type>phone-template</type>
<version>68850</version>
basically same Problem here - Updated Snom D375 to current firmware und 3CX Clients to 15.5 SP1 (At the same time...), and CTI stopped working. (We are using customized templates.)
Can you please provide the solution here instead of PM? Thank you.
