Is it really common practice to ask for payslips? Jesus, that sounds way too far for me. I was once asked for a payslip, but I'm young, am in a well-paying speciality field, and was being interviewed for a position outside of it as a favour to a recruitment agent. If I were ever asked for a payslip at an interview that wasn't in some way anomalous, I'd balk at it and probably walk out.
Also, what kind of company/HR department gives out salary details to randoms who call them for references? That's enormously unethical. While I'm effectively a salaried worker, I am remunerated at an hourly rate (at a fixed number of hours a day). Thankfully, in the past, that's allowed me to reply to, "How much do you earn?" with, "Well, I would charge you x."
