Incall mean you visit the girl. Outcall means that she visits you.
Incall: The client comes to the place of business of the escort.
Outcall: The escort goes to the place where the client is staying.
Notes:
- Not all escorts will do both. A lot will have a preference for one or the other. Ensure you check their website or advertisement before you call.
- It is not guaranteed that an escort will go to your home. Normally a hotel is preferred. In Australia, some outcalls will only go to 5 star hotels.
- In Australian brothels, if you have never been there before, it may be required that you come and prove your identity before they allow a escort to come to your hotel.
In general,
Incall is when you go to a place to receive a service, as opposed to an outcall when the person providing the service comes to the place where you are.
