Sorry pal, the image you're giving here is one of a control freak keeping a prostitute in your thrall for the exact period of the booking...
Yes, she should be able to use her phone every now and again to check in with her pals/pimp to let them know you haven't murdered her.
You shouldn't be expecting to spend a whole overnight fucking her or talking to her, that's crazy talk...
I'd suggest if you're asking such a question you're maybe not ready for it.
