There are obviously going to be some circumstances when a player may have to take an emergency call, and that is understandable. I am currently in that position and so on the 1st tee I always advise my playing partners of the circumstances and ask if it's ok with them that I might have to take a call. If I do have to take a call I try and make sure that I don't inconvenience or delay anyone playing. I have phone on silent and check it from time to time. Calling back when it is appropriate for me to do so, take as little time as possible, and absolutely don't initiate calls.
I do this … my parents are both in their 90s, so there is the occasional emergency.
