Two-way number masking allows both parties to initiate calls to each other using the masked number. Unlike one-way masking where only one party can call, two-way masking works in both directions: either party dials the same virtual number and is bridged to the other, with routing decided by who is calling. Essential for ongoing buyer-seller relationships and service provider communications. This is available today through the Session API — one request binds two real numbers to a virtual number for a set lifetime (from a minute up to 30 days), and either party can call that number until the session expires. Persistent pairs with no expiry are supported too, and you can extend, pause, resume, or end a session at any time.
