More About Voice Mail 
Voice Mail Ports are configured on Form 43-Port-02. Setting this parameter to a value of 8 identifies it as a 
voice mail port. It will then receive the integration digits selected for the system. All voice mail ports in a system 
must be set to type 8. 
All Message Waiting levels for Voice Mail ports must be 9. Message Waiting level is set on Form 46-ext-02. 
Voice mail ports must be assigned to Hunt Group 1 in the TD-1648i. The Pilot number for Hunt Group 1 is 
assigned on Form 67-01. Individual member of Hunt Group 1 are programmed on Form 68-01-01 for Day 
Service and 69-01-01 for Night Service. 
When a voice mail port sets a message waiting on an LCD display set, the callback number displayed will be the 
first member of the hunt group. Message callbacks will call the station displayed. If it is busy, the system will 
hunt, just as if you had dialed the pilot number of the hunt group.
