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 trunk outbound line group has DDI/DID mode enabled,

and sets the DDI/DID Mask to 0.
Clear this to use the SIP request URI to do the DDI/DID mapping.

number(s).
Use this section to manage the DDI/DID numbers which allow outsiders to call and reach
extensions directly.
