The method used by an escort booking agency to ensure maximum utilization of their resources. The objective is have the next customer available on site to ensure minimum down time, but at the same time ensure the previous customer has left and the girl has had a chance to clean up before her next "date".

The first call will provide general location information (such as the name of a hotel) while the second call (which occurs after arrival at the location) will provide more detailed information such as a room number.
After making an appointment with the agency, it was a standard two-call system to get to the girl's room.

Get the two-call system mug.
Two Call Process is where an escort uses two phones calls from you to verify you're legit. The first will take you to a a neutral spot such as a gas station or a fast food parking lot (This usually puts you within 3 blocks or 3 minutes of the place, the "3x3 Rule" ). Once you get there, she will have you call again to get the address.
Yes, i use a standard two call process. Go to the gas station on the corner of MLK and Getiton. Call me when you get there, and I'll give you my address.
