These people would be able to converse with you on Telegram but would not be able to find your phone number on the app/site.
Wire is a platform/client that allows setting up accounts with email address and/or phone number, although when I set it up I had to provide a phone number. Contact sharing is not perfect yet. It also has end-to-end encryption by default, has multi-device and multi-platform sync, and some other cool features (doodling, for example).
