DID actually stands for Direct Inward Dialing. When I've set this up in the past you have a PBX (private branch exchange-either a commercial product purchased by your company or Asterisk) which you connect to a PRI (voice T1-basically a special network connection that has 16? voice lines on it). The phone company sends a digital signal containing the phone number people are dialing so the PBX can figure out who to send the call to.
What are you trying to do with DID?
