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.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Moreover when Freeswitch receives an initial noSDP Invite it respond with it’s full capabilities which is desired behaviour.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></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.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I would appreciate any clues and hints how to deal with this issue.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Helv,sans-serif;color:black">Best Regards<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:10pt;font-family:Helv,sans-serif;color:black"><br></span><b><span style="font-size:8pt;color:black">Tomasz Skaba</span></b><span style="font-size:7pt;color:rgb(0,161,224)"><br></span><span style="font-size:8pt;color:rgb(0,161,224)">Projektant<br>Pion Telekomunikacji i Mediów</span><span style="font-size:7pt;color:black"><br><b><br></b></span><b><span style="font-size:8pt;color:black">Asseco Poland S.A.</span></b><span style="font-size:8pt;color:black"><br>ul.
