If I have my number displayed I have an autoreply that tells them the times I'm available, where I am and please call to book or leave a message. I'll pick up if I can but if I miss the call / text they get the autoreply. I prefer emails anyway but alternatively a phone call. A text tells me nothing apart from they are lazy, it's fine if I know someone but not for new.
A phone call tells me a lot, rough age, accent, polite or not, pushy or not, stupid, cocky, friendly etc, all things a text would not reveal. A text alone will not get a reply from me other than my autoreply.
