hello, i got a strange issue ... I'm using FS as a redirect server (route server) and it does work fine ... except if the original INVITE contains a Diversion header, the same header is lost in the responding 300 or 302 message. Is this by design or its a bug ? this is a part of the code in sofia where u construct redirect response message... if (argc > 1) { nua_respond(tech_pvt->nh, SIP_300_MULTIPLE_CHOICES, SIPTAG_CONTACT_STR(dest), TAG_IF(!zstr(extra_headers), SIPTAG_HEADER_STR(extra_headers)), TAG_END()); } else { nua_respond(tech_pvt->nh, SIP_302_MOVED_TEMPORARILY, SIPTAG_CONTACT_STR(dest), TAG_IF(!zstr(extra_headers), SIPTAG_HEADER_STR(extra_headers)), TAG_END()); } so, why the original diversion header is missing ? ... m'I missing something ? also, should the 3000/302 message always contain a diversion field saying the call is diverted ? Thanks for your answer, Tihomir.
