Hi Mick,<br><br>What is the call flow in this case? I'm curious to know what call legs exist and where the 180/183 is and is not happening. FreeSWITCH generally does all this for you, so I suspect there's a gremlin in the works. Can you pastebin a console debug log w/ SIP trace? That may give the gang here just enough information to figure out what's going on.<br>
<br>Thanks,<br>MC<br><br><div class="gmail_quote">On Mon, Oct 8, 2012 at 2:26 AM, Mick Stevens <span dir="ltr"><<a href="mailto:mickstevens@yahoo.com" target="_blank">mickstevens@yahoo.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

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">

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>
