State table applications

I want to make a call from Blueworx Voice Response to a SIP phone. How do I write a state table application that can do this?
Create the following actions:
  1. AssignData:
    • Operand=Put Tag
    • Operand 1=TO_HDR
    • Operand 2=sip: sip address of client
    • Result=SV541
  2. MakeCall

    Set Dialled Number and the format string to dummy values such as 0000 and ####

  3. PlayPrompt
  4. CloseEverything
I try to make a call into Blueworx Voice Response from a SIP phone, but the INVITE is not received.
Ensure that the stack has been started on the same Ethernet port that you are sending to. See Setting the SIP transport IP address.
