In order for authentication to work it seems that the standard UAC scenario XML file needs to be extended as follows (copied from the example in the manual):

Built in scenarios are part of the executable code. In order to dump an existing scenario into a file use the following command:

...

Panel

-3pcc ip:port : Launch the tool in 3pcc mode ("Third Party
call control"). The passed ip address
is depending on the 3PCC role.

  • When the first twin command is 'sendCmd' then
    this is the address of the remote twin socket.
    Example: 3PCC-C-A scenario.
  • When the first twin command is 'recvCmd' then
    this is the address of the local twin socket.
    Example: 3PCC-C-B scenario.

-nr : Disable retransmission in UDP mode.

Panel

-nd : No Default. Disable all default behavior of SIPp
which are the following:

  • On UDP retransmission timeout, abort the call by
    sending a BYE or a CANCEL
  • On unexpected BYE send a 200 OK and close the call
  • On unexpected CANCEL send a 200 OK and close the call
  • On unexpected PING send a 200 OK and continue the call
  • On any other unexpected message, abort the call by
    sending a BYE or a CANCEL

-rsa host:port : Set the remote sending address to host:port.
