Yes let me explain my point as I was not that clear.
When an Agent receives a phone call, email or a chat on teams, instead of opening directly a ticket (incident or request) he will open a call and then from that will create a ticket a ticket (incident or request) by assigning the correct Help Topic.
I've attached an example from Service Now.
Consider the following
Call type is : Request or Incident (in our case the correct Help Topic)
Contact type : Phone, Email, Teams
