NEC 28i System Manual page 113

- In Program 0416, disable (0) Item 1. This disables Voice Mail
Call Screening. If you left screening enabled, Voice Mail ports
could call the wrong extensions. For example, a Voice Mail
port trying to call screen extension 130 would outdial 1130.
This would call extension 113 instead. Extension numbers now
will correspond to room numbers, and all the Service Codes in
the 100 series will be in the 700 series.
If you are programming two digit codes in the PC Program,
make sure the Dial Type entry for nX is F. This "unlocks" the
two digit entries. This step is not necessary when using the
Telephone Program (which automatically enters 15).
