To configure the Incoming Reference Table,
• Determine the SIP Trunk on which you want to apply the DDI logic.
• On the SIP Trunk, assign an Incoming Reference ID number. To do this,
• Login as System Engineer.
• Under Configuration, click SIP Trunk Parameters.
• Click Incoming Call to expand. Scroll to Incoming (IC) Reference ID.
• Assign an Incoming (IC) Reference ID number for each time zone.
• Under Configuration, click DDI Routing.
•Click Incoming Reference Table and configure the following parameters:
• IC Reference ID: You must configure the parameters to apply DDI Routing against the same ID as
assigned on the SIP Trunk. This ID is a link between the port settings and the Incoming Reference
Table.
• DDI Routing Reference ID: Enter the DDI Routing Reference ID number. As per the this reference
number the system checks the DDI Routing Table and determines the final landing destination for
placing the call.
This ID is a link between the Incoming Reference Table and the DDI Routing Table.
• Route on First Destination: When the final destination extension is identified as per the DDI number
table, the system checks if this check box is enabled. If it is enabled, every incoming call will always be
placed on the first extension configured in the DDI Table. If the check box is clear, the call is routed to
the respective extension number.
• Ring Timer: This timer signifies the time for which the extension on which the incoming call is placed
must ring. On expiry of this timer if the call is not answered the call is routed as per the option you
configure for the parameter When No Reply.
• When No Reply: When the call is not answered by the DDI extension, the system checks the option
you have selected for this parameter and processes the call further. You may select any option from the
following:
• Disconnect the call
• Route the call to Trunk Landing Group
• Route the call to Voice Mail, that is to the Mail box assigned to the DDI extension. For this, a mail
box must be assigned to the extensions. If the extension is not assigned mail box, the caller will
hear the welcome message of the VMS, but will not be able to access the mail box.
• When Busy: If the DDI extension is busy, the system checks the option you have selected for this
parameter and processes the call further. You may select any option from the following:
• Disconnect the call.
• Route the call to Trunk Landing Group.
• Route the call to Voice Mail, that is to the Mail box of the DDI extension. For this, a mail box must be
assigned to the extensions. If the extension is not assigned mail box, the caller will hear the
welcome message of the VMS, but will not be able to access the mail box.
