Each system directory and personal directory number stored in the configuration can be optionally assigned an index number. That index number can then be used by M-Series and T-Series phone users to dial the directory number. This short code feature allows the creation of short codes to perform the same function. However, the short code is diallable from any type of telephone extension on the system.

For example:

• If Feature 0 is followed by a 3-digit index number in the range 000 to 999, the system directory record with the matching index number is dialed.

• If Feature 0 is followed by * and a 2-digit index number in the range 00 to 99, the personal directory record with the matching index number is dialed. Alternatively Feature 0 can be followed by 00# to 99#. Note: Release 10.0 allows users to have up to 250 personal directory entries. However, only 100 of those can be assigned index numbers.
