I, personally, do not answer my phones during an appointment, having said that I have been given abuse by guys saying that they're been ringing me & I don't answer, I do tell them I only answer my phone when I'm not with a client. I have also had guys turn up at my door because I haven't answered their call so they think it's more discreet to just turn up without an appointment, they fail to understand that me not answering my phone means I'm not available.
