Or better yet, provide the important details over email and then if there is some unimaginable reason why an audio medium is still required to convey information (identify a bird call? place a long distance call with a whistle?) then contact over the phone.
Because this assumes the person is always contactable by email. There is a none zero chance that the person is available for a phone call but not in front of email.

Just put your phone on silent or don’t answer it if you’re not available.
