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 3.5, it was impossible to...

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 3-28.

The DID number may have from 1 to 4 digits (typically 4).
Each DID Trunk Interface card (VB-44520) supports up to 8 DID trunks.
