• 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 a
destination 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 number
tenant group/ DIL incoming CO tenant group.

DIL Ringing

DIL Ringing allows calls on a specific CO 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 a trunk 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 3.0, it was impossible to distinguish between Private Line incoming calls and
Directory Number incoming calls. Version 3.0 and higher allows the person receiving the call to
easily distinguish between these types of incoming calls.
