Two-way DID Trunk - An ISDN PRI (or T1) line equipped for direct inward dialing. Most trunks are related to a given phone number, either alone or as part of a hunt group. In the case of a "normal" (ie analog) DID Trunk a group of phone numbers are associated with that DID trunk (or group of trunks) and incoming calls include the DID Number, so the PBX can route that call to the correct DID Extension. This is exactly how ISDN PRI functions, with the DID information coming in over the D Channel. There is a big difference between a normal DID Trunk and a Two-way DID trunk over ISDN PRI. For one thing, ISDN PRI is digital. More importantly, you cannot dial out over a true DID trunk and you can dial out over a PRI. See DID
