SIP "To" Header
Select this if this auto-attendant interacts with a SIP server that uses the SIP To header to
do the DDI/DID mapping. If this SIP trunk outbound line group has DDI/DID mode
enabled, using this deletes all of the this SIP trunk outbound line group’s DDI/DID
mapping settings and sets the DDI/DID Mask to 0.
Clear this to use the SIP request URI to do the DDI/DID mapping.
DDI/DID Mask
Enter a number (0~10) to decide the number of digits you want to enter for the next DDI/
DID number(s). 0 means you can enter any number of digits for the next DDI/DID
number(s).
