Section 700 - Operation Chapter 3. System FeaturesICX-40-700 ICX (International) issued December 1999 3-15Depending on the assignments in the DID Table, names or exchange line numbers are displayed.(Names can be up to 10 digits long.)DID Ringing can be very useful by sending calls directly to a specific extension, hunt group, etc.based upon the number dialed. Since a relatively small number of exchange lines handle the DIDcalls, this can be more cost efficient than DIL exchange lines or attendant group answering andtransfer. (DID may send a call to a group using the Virtual Extension feature.) DID Busy/DelayedRinging is also available with DID Ringing. (See “DID Day/Night Busy/Delayed Ringing” on page 3-41.)For more information on DID CO/Exchange line Interface, see “CO/Exchange Line Interface - DID(H.K. Only)” on page 3-17.Considerations• Caller ID takes priority over the DID name assignment.• Only one of the two DID tables may have name assignments.• If the DID/DIL destination is a Directory Number (DN), the call goes to an extension that has adestination key even if the Primary Directory Number extension is busy or does not answer.• If the DID/DIL destination is an UNA extension, the UNA will ring depending on DID numbertenant group/ DIL incoming CO/Exchange line tenant group.DIL RingingDIL Ringing allows calls on a specific CO/Exchange line to be directed to ring a specific extension,System Speed Dial (SSD) number (for redirecting calls out), and hunting group.This can be very useful when an exchange line is dedicated to a specific person or purpose. However,this can be a more expensive use of the line since it has a more limited use.Prior to Version 4.0, it was impossible to distinguish between Private Line incoming calls andDirectory Number incoming calls. Version 4.0 and higher allows the person receiving the call toeasily distinguish between these types of incoming calls.Considerations• If the DID/DIL destination is a Directory Number (DN), the call goes to an extension that has adestination key even if the Primary Directory Number extension is busy or does not answer.• If the DID/DIL destination is an UNA extension, the UNA will ring depending on DID numbertenant group/ DIL incoming CO/Exchange line tenant group.
