Number masking is a method used to protect personal phone numbers by routing calls or messages through a temporary proxy number. This ensures that the caller’s or recipient’s real number remains hidden.
IMPORTANT: Aircall does not currently support **Number Masking**. This feature is distinct from **Call Spoofing**, which is also not supported by Aircall.
