6.9.3 Post-Answer Redirection With UUI to a SIP Destination
This section provides an example of post-answer redirection with UUI passed to a SIP destination.
In this example, the inbound call is routed to VDN 10003 shown in the following screen. The
originally dialed Verizon toll-free number may be mapped to VDN 10003 by Session Manager
digit conversion, or via the incoming call handling treatment for the Communication Manager
trunk group handling the call.
To facilitate testing of NCR with UUI, the following vector variables were defined.
VDN 10003 is associated with vector 3, which is shown below. Vector 3 sets data in the vector
variables A and B (steps 03 and 04) and plays an announcement to answer the call (step 05). After
the announcement, the route-to number step includes ~r+18668512649. This step causes a
REFER message to be sent where the Refer-To header includes +18668512649 as the user portion.
The Refer-To header will also contain the UUI set in variables A and B. Verizon will include this
UUI in the INVITE ultimately sent to the SIP-connected target of the REFER, which is toll-free
