Programming Steps

NOTE: In this example, Mode 1 is defined as Day, Mode 2 is defined as Night, and we will make Trunk 04 ring exclusively to extension 105.

1. Go to Program 22-02: Incoming Call Trunk Setup

2. Set Trunk 04, Mode 1 and Mode 2 to DIL


3. Go to Program 22-07: DIL Assignment

4. Set Trunk 04, Mode 1 and Mode 2 to Extension 105
This will now terminate Trunk 04 to only ring on extension 105 for Day, Mode 1 and for Night, Mode 2.


5. Go to Program 24-09: Call Forwarding Fixed Settings

6. Select Extension 105 from the ICM Extension dropdown menu


7. Set Program 24-09-01: Call Forward Type to Call Forward Busy/No Answer

8. Set Programs 24-09-02 through 24-09-05 to “3999”
Note: 3999 is the default Virtual Extension Voicemail Pilot number. If you have altered your system and/or extension numbering, then confirm your virtual extension voicemail pilot number in 11-07.
