Matrix ETERNITY NE System Manual 563
If there is no reply from the dialed extension, you can have the call disconnected instead of routing it to the 
Operator by enabling the Disconnect DID call, when dialed number is not responding flag in the 
System Parameters.
DID with Voice Mail Auto Attendant
When the Voice Mail Auto Attendant of ETERNITY NE is selected as the destination for incoming calls on a trunk, 
this is how DID will work:
• A call lands on a CO Trunk.
• The Voice Mail System (VMS) installed in the ETERNITY NE answers the call.
• The VMS greets the caller with the Welcome messag and the Greeting Message selected for the current 
time zone (working hours and non-working hours).
• The VMS plays prompts to the caller to process the call further according to the Voice Mail Auto Attendant 
Profile you assigned to the trunk. 
Delayed DID
You can use Delayed DID to have incoming calls not answered by the landing destination(s)—Operator or 
Extensions—within a certain time period, to be handled either by the Built-In or the Voice Mail Auto Attendant.
When you use Delayed DID,
 
• As a call lands on a trunk, the system checks the Incoming Call Route configured for the current time zone 
for the trunk.
• On finding Operator or Extensions as the landing destination, the system rings on the destination 
extension(s) for the duration of time defined for ringing the extension (default: 10 seconds).
• If no reply is received from the extensions, the system routes the call to the auto attendant you selected: 
Built-In or Voice Mail Auto Attendant.
• The call is processed further by the auto attendant you selected.
How to configure
To use the Voice Mail Auto Attendant on trunks, do the following:
1. make a list of the trunks by their port type (“CO Trunks”, “Mobile Trunks”, “SIP Trunks”) and port number 
on which you want to use the Voice Mail Auto Attendant. 
2. configure Welcome and Greeting messages. You may either use the default, pre-recorded welcome 
messages of the VMS, or record in WAV format, the custom welcome messages that meet your 
requirements. See “Recording Voice Messages”
3. configure “Graphs and Nodes”.
