[OpenSER-Users] Why 'sip_trace' desn't show ACK for a "200 OK" from OpenSer to UAS?

(Sorry, I sent this mail to devel maillist) Hi, the first I do in my OpenSer script is: -------------------------------------------------------- modparam("siptrace", "trace_flag", FLAG_SIPTRACE) modparam("siptrace", "trace_on", 1) route { ### SipTrace. if ! is_method("OPTIONS|REGISTER") { sip_trace(); setflag(FLAG_SIPTRACE); } ... -------------------------------------------------------- When an INVITE gets a 200 OK the UAC sends an ACK (end to end). This ACK from UAC to OpenSer is stored in 'sip_trace' table, but the same ACK from OpenSer to the UAS (in-dialog ACK) is not stored, why? Is there any reason for this? AFAIK this ACK is like any in-dialog request and 'sip_trace' stores correctly both legs of any in-dialog request, except in the case of an ACK for a 200 OK. Since the "special" treatment OpenSer performs in the ACK, maybe there is a technical issue that makes imposible ACK from OpenSer to UAS to appear in "sip_trace"?
