I dislike phone calls, but handle them in two ways: If a chat conversation isn't getting a point across after a couple of back and forths (five minutes is too long,) then it's time for a phone call. Discussions in chat are fine. Flat out lack of understanding is best fixed when they can hear and interrupt for clarification. If I do need to call someone, I simply message them and ask if they're available for a call. There's no need for preamble.
