Skype for Business calls from Access form? (1 Viewer)

My workplace is moving to Skype for business for telephone calls. Initially it will be for internal communication, but the next stage will be to use Skype for VOIP calls for all phone communication.

I would like to set up a command line to be able to click-to-call phone numbers directly from Access forms. I assume it will be through a SHELL function.

Any suggestions as to how I might be able to set this up?

It would appear you can use a web URL based api type call :
