Input: Question: If you, for example, have to add a person to an application whilst that person is on the phone, how do you politely ask for that person's gender if the voice and/or name has not proven decisive? To clarify why I posted this question on this site: I was looking for an answer within the context of the English language and usage. The given answers have proven that this question really isn't off-topic, other languages know different distinctions that are relevant to addressing this issue. 
Answer: I would simply ask, "Which box should I check?, M or F?, and keep in mind, this phone call is monitored"...a barely audible snicker should convey 'politeness', followed by , "seriously, we have a pool going on and I need to get this one right!".

no
