Twilio Proxy simplifies the task of masking the communications between two parties (aka [masked phone numbers](/docs/glossary/what-are-masked-phone-numbers) or masked calling). Proxy automatically provides a number and associates two numbers together in order to forward messages and calls back and forth.

With Proxy, Twilio facilitates any use case that can benefit from a temporary conversation between two parties.
