In Outlook (2016/365), when you select a contact, there's an option to call that contact
When you select the option to call the person, Outlook seems to ignore the Windows 10 settings for 'tel:' or 'callto:' protocol handlers and present you with a dialer. Or, when Microsoft Teams is running, it will call the number through Teams.
I'm looking for a way to make the call through my own VOIP app.
Does anyone know if Outlook follows a specific protocol handler or how I can override its default behaviour?
I know it's possible to create a plug-in to add my own dialing options in a separate menu, but I'm looking for a way to override the behaviour of this default menu.
Thanks!
