I would like to make a phone call directly from within eM client
Sorry, not possible.
It is possible to call e.g. via Skype through the Sidebar on the right of eM Client’s window:
If you right-click the telephone number, you will see a context menu with the option ‘Call (contact’s number)’. Click on it, select which program you’d like to proceed with and check ‘Always use this program’.
If that doesn’t work, you can also manually assign the CallTo command in Control Panel\Programs\Default Programs\Set Associations. Scroll to the second part of the Window that says ‘Protocols’, select CALLTO and Change program with the button in the top right corner.
I do not get that option when i right click and when i enter associations , call to is associated with skype and i cannot select any other program. I running windows 10 and em client 7.02
What program exactly are you trying to use? Can you please verify that it works with the callto protocol?
