A DID (direct inward dialing) number is a phone number that routes incoming calls directly to a specific endpoint on your phone system, without a separate physical line for each number. Calls arrive over a SIP trunk or the internet, so one connection can carry hundreds of numbers to your PBX, softswitch, or contact center platform. didlogic DIDs are an integrated SS7-SIP product: the same local carrier connection carries inbound and outbound calls with the native caller ID, so outbound calls show the same local number your customers dial. In 17 countries the service runs on a licensed local voice model, supporting emergency calling and short-code dialing like a national telephone provider. ## FAQ ### What is the difference between DID numbers and traditional phone numbers?
