ORS: how to retrieve SIP URL (including URL parameters) of INVITE

A SIP UA connects to SIP Server on a routing point for which a SCXML document is defined. How can I retrieve the SIP URL of the INVITE in the SCXML. As far as I can see, I can only access the DNIS which is the number of the routing point.

I want the testers of my routing application to be able to define additional test parameters on the SIP URL (e.g. sip:5556667777@sipserver;time_of_day=21:00;date=20131225) directly by modifying the URL in the SIP soft phone they’re using for testing the app. So I would need ORS to access the URL parameters in order to have a special test behaviour.

thanks.

SCXML do not have direct access as VXML to SIP messages or any other CSTA message. What can be done with SIPS is to map header or R-URI to attached data and access attached data from SCXML. In case of R-URI please add section INVITE to SIP Server options and inside section add options:
userdata-1 = INVITE:time_of_day
userdata-2 = INVITE:date

Thanks
