Be sure the call comes to a phone that you won't have on when you have any company around.

Tell her to leave you a time that you can call back and reach her.

Im interested in making an appointment with
an escort. But she has someone else scheduling
appointments for her over the phone.

Thanks.

of time when it's OK for her to call you.  Many providers use assistants to make their appointments, it's not really a big deal.  Just say, 'you can call me at whatever number, between this hour and that hour.'  Many providers will not return calls if they do not know when it's safe to call, so you need to tell her.

great thanks for the info
