•

Caller ID takes priority over the DDI name assignment.

•

Only one of the two DDI tables may have name assignments.

•

If the DDI/DL 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 DDI/DL destination is an UNA extension, the UNA will ring depending on DDI number 
tenant group/ DL incoming trunk tenant group.

DL Ringing allows calls on a specific trunk 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.

DISA Ringing (which is related to the DISA feature) allows a trunk specified as a DISA trunk to ring 
and give off-site users dial-in access to the System. Once the DISA trunk is accessed, the user receives 
dial tone and may dial an extension. 

For more information on DISA, see “Direct Inward System Access” on page 38.

Multiple Ringing allows trunk calls into the System to be directed to ring multiple extensions in the 
System. This can be very useful when anyone in a group may answer a call. This can also be very 
useful at night when only a selected number of people are available to handle calls.
