Per RFC3261, SDP answers can actually come in any non-100 1xx provisional reply, not just necessarily 183, or 180, or PRACK.

Thanks Ovidiu,
readme is online at: http://kamailio.org/docs/modules/devel/qos.html
Is the module keeping track of all session negotiated, or is stores the last one (used)?
Happy holidays! Daniel

Hello,
QoS is an new module that can be used to track per dialog SDP sessions. The QoS module is sitting on top of the dialog module and provides an API to be used by other module. The QoS module does not provide any scripting functionality (it is a passive module). See the module documentation for more informations.
SDP session(s) can be inspected via the dialog dlg_list_ctx MI interface command: dialog:: hash=3732:573385728 state:: 4 timestart:: 1230068558 timeout:: 1009 callid:: d3d816cce3e24a19b937b56e4689e524 from_uri:: sip:111111111@10.11.10.63 from_tag:: 8c85c079 caller_contact:: sip:111111111@10.11.128.129 caller_cseq:: 100 caller_route_set:: caller_bind_addr:: udp:10.11.10.63:5060 to_uri:: sip:222222222@10.11.10.63 to_tag:: 43FED9C4-20CF callee_contact:: sip:222222222@10.111.3.241:5060 callee_cseq:: 100 callee_route_set:: callee_bind_addr:: udp:10.11.10.63:5060 context:: qos:: negotiated_sdp sdp:: m_dir=1 m_id=1 method=INVITE cseq=100 negotiation=1 session:: callee cnt_disp= bw_type= bw_width= streams=2 stream:: 1 media=video IP=10.111.3.241 port=0 transport=RTP/AVP payloads_num=0 stream:: 0 media=audio IP=10.111.3.241 port=17240 transport=RTP/AVP payloads_num=3 payload:: 2 rtpmap=100 codec=X-NSE payload:: 1 rtpmap=101 codec=telephone-event payload:: 0 rtpmap=0 codec=PCMU session:: caller cnt_disp= bw_type=AS bw_width=400 streams=2 stream:: 1 media=video IP=10.11.128.129 port=22804 transport=RTP/AVP payloads_num=2 payload:: 1 rtpmap=34 codec=H263 payload:: 0 rtpmap=107 codec=H263-1998 stream:: 0 media=audio IP=10.11.128.129 port=22800 transport=RTP/AVP payloads_num=12 payload:: 11 rtpmap=112 codec=iLBC payload:: 10 rtpmap=100 codec=AMR payload:: 9 rtpmap=13 codec=CN payload:: 8 rtpmap=101 codec=telephone-event payload:: 7 rtpmap=111 codec=G726-40 payload:: 6 rtpmap=110 codec=G726-32 payload:: 5 rtpmap=109 codec=G726-24 payload:: 4 rtpmap=108 codec=G726-16 payload:: 3 rtpmap=4 codec=G723 payload:: 2 rtpmap=18 codec=G729 payload:: 1 rtpmap=0 codec=PCMU payload:: 0 rtpmap=8 codec=PCMA
