An incall address means a flat or a room that somebody is keeping for this purpose. Somebody has to rent it, somebody has to be there, and in Delhi somebody has to deal with the neighbours, the landlord and whoever eventually knocks. That risk does not fall on the agency and it does not fall on you. It falls on the women who are sitting in it.
The second problem is what an incall address turns into. A room with several women working out of it stops being an arrangement between adults fairly quickly - it is the structure that makes it possible for somebody to be kept there. The absence of a premises is not an inconvenience on a site like this; it is most of what makes it honest.
So the practical consequence: you arrange the room, and nothing is taken from what you pay for it. The note on which Delhi hotels take a guest covers the part of that which is actually difficult.
An incall address advertised anywhere in this city comes with a share of somebody else’s danger attached to the hour, and it is usually discounted for precisely that reason.
