I'm looking for a mechanism that would allow for easy scheduling of in person appointments from a service desk project.
The generic use case is: a customer emails us to get help with their office desktop (we're an IT shop) and we want to send a technician out to meet them in person. Right now we ask them to call us to set up an appointment and someone has to manage the google calendar. Ideally there would be some sort of mechanism that would allow the customer to select an appointment time via the portal.
I've looked around for an add-on, but can't seem to find anything. Does anyone have a recommendation or know whether or not this is possible with service desk?
