With SIP over UDP, when packet fragmentation happens, it destroys the SIP packet as UDP does not auto-reassemble the fragments… this happens once your sip packets exceed MTU… the only fix is small packets. That means compact headers, eliminating extra headers, or just don’t use such a big SDP by eliminating CODECs you don’t need.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">The affect with FS is if you don’t have media_mix_inbound_outbound_codecs set to true, only codecs offered to FS on the A leg are passed to the B leg, this reduces the size of the SDP and has the side effect of greatly reducing the amount of transcoding.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif"> <a href="mailto:freeswitch-users-bounces@lists.freeswitch.org" target="_blank">freeswitch-users-bounces@lists.freeswitch.org</a> [mailto:<a href="mailto:freeswitch-users-bounces@lists.freeswitch.org" target="_blank">freeswitch-users-bounces@lists.freeswitch.org</a>] <b>On Behalf Of </b>Luiz Fernando Softov<br><b>Sent:</b> Thursday, July 14, 2016 5:10 PM</span></p><div><div class="h5"><br><b>To:</b> FreeSWITCH Users Help <<a href="mailto:freeswitch-users@lists.freeswitch.org" target="_blank">freeswitch-users@lists.freeswitch.org</a>><br><b>Subject:</b> Re: [Freeswitch-users] INCOMPATIBLE_DESTINATION -
