The scenario is as follows:<o:p></o:p></p><p class=MsoNormal>(A) -- INVITE (SDP1) --> (Freeswitch)<o:p></o:p></p><p class=MsoNormal>(A) <-- 200OK (SDP2) – (Freeswitch)<o:p></o:p></p><p class=MsoNormal>(A) – ACK --> (Freeswitch)<o:p></o:p></p><p class=MsoNormal>(A) – INVITE (noSDP) --> (Freeswitch)<o:p></o:p></p><p class=MsoNormal>(A) <-- 200OK (SDP3) – (Freeswitch)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>For clarity i skipped non important messages. The important thing is that when Freeswitch receives noSDP reInvite it responds with last negotiated SDP (same codecs list) so in above scenario SDP3=SDP2. According to RFC UAS should send its full capabilities so i think Freeswitch should send as many codecs as it would send in response to initial Invite in late-offer.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Moreover when Freeswitch receives an initial noSDP Invite it respond with it’s full capabilities which is desired behaviour.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The version of Freeswitch we are using is 1.2.10 but i confirmed on newest version that the behaviour is the same.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I would appreciate any clues and hints how to deal with this issue.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Helv",sans-serif;color:black;mso-fareast-language:PL'>Best Regards<o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-size:10.0pt;font-family:"Helv",sans-serif;color:black;mso-fareast-language:PL'><br></span><b><span style='font-size:8.0pt;color:black;mso-fareast-language:PL'>Tomasz Skaba</span></b><span style='font-size:7.0pt;color:#00A1E0;mso-fareast-language:PL'><br></span><span style='font-size:8.0pt;color:#00A1E0;mso-fareast-language:PL'>Projektant<br>Pion Telekomunikacji i Mediów</span><span style='font-size:7.0pt;color:black;mso-fareast-language:PL'><br><b><br></b></span><b><span style='font-size:8.0pt;color:black;mso-fareast-language:PL'>Asseco Poland S.A.</span></b><span style='font-size:8.0pt;color:black;mso-fareast-language:PL'><br>ul.
