DIDx or DIDXchange is the world's first and largest DID/DDI (Direct Inward Dialing Numbers) exchange. It made the debut with 100 future-thinking ITSP members in August 2005. Just over one year later, it is 3500+ members strong. With one simple interop, the a new member has an immediate interconnect with all.

DIDX is a wholesale only DID number marketplace that enables ITSPs to be a DIDX Seller and provide numbers from different parts of the world, from their own web sites. DIDX pays the DID Seller after the DID Buyer buys.

DIDX provides free of charge billing service to sell DID numbers via the DIDx network to any other ITSP anywhere in the world using SIP or IAX2 protocol.

Didx gives FREE APIs to add DIDs to DIDx network and free API for DIDs to be displayed on provider's web site, free of charge, until sold.

Once they are sold, the DID's are instantly routed to the customer's SIP address.
