I'm curious to know what call legs exist and where the 180/183 is and is not

Does anybody know a way I can get FreeSWITCH to generate a 180 or 183 with SDP upon receipt of a 180 without SDP?</div><div style="font-style: normal; font-size: 16px; background-color: transparent; font-family: arial, helvetica, sans-serif; ">

example).</div><div style="font-style: normal; font-size: 16px; background-color: transparent; font-family: arial, helvetica, sans-serif; "><br></div><div style="font-style: normal; font-size: 16px; background-color: transparent; font-family: arial, helvetica, sans-serif; ">
The context behind my enquiry is that I send traffic to another SIP carrier that then hands the traffic off at ISUP. Where the ISUP carrier sends back an ACM with a backward call indicator of "subscriber free" the carrier sends a 180 without SDP to me/FreeSWITCH assuming that any ringback tones will be generated by the SIP user agent (RFC 3398 blah, blah, blah).</div>
