• The VMS greets the caller with the Welcome message and the Greeting Message selected for the current
time zone (working hours, break hours and non-working hours).
• If the system detects the day as a holiday, the VMS plays the Holiday Message. To know more, see
“Holiday Table”.
• The VMS plays prompts to the caller to process the call further.
Delayed Auto Attendant
You can use Delayed Auto Attendant to have incoming calls that are not answered by the landing destinations—the
Operator and the Trunk Landing Group—within a certain time period, to be handled either by the Voice Mail Auto
Attendant.
When you use Delayed Auto Attendant,
• as a call lands on a trunk, the system checks the incoming call routing configured for the current time zone
for the trunk.
• on finding Delayed Auto Attendant enabled, the system rings on the destination extensions (Operator and
Trunk Landing Group) for the duration of time defined for ringing the extensions (default: 10 seconds).
• if no reply is received from the extensions, the system routes the call to the Voice Mail Auto Attendant.
• the call is processed further by the VMS.
How to configure
To use the Voice Mail Auto Attendant on trunks, do the following:
1. Make a list of the SIP trunks and their port numbers on which you want to use the Voice Mail Auto
Attendant.
2. In the “Trunk Feature Template” assigned to these trunks,
• enable the Voice Mail Auto Attendant check box for the desired time zones.
• select the desired Voice Mail Auto Attendant (VMAA) Menu.
3. Complete the VMS related configuration.
• Configure Welcome and Greeting messages. You may either use the default, pre-recorded welcome
messages of the VMS, or record the custom welcome messages that meet your requirements, in .WAV
file format.
• Configure the Voice Mail Auto Attendant (VMAA) Menu parameters.
