When a re-invite happens the Adtran gets all confused about call stats and marks the pre-reinvite leg of the call as losing large numbers of packets. BTW, IIRC reinvites happen when a codec changes or the channel switches to T.38.</span></p><p class="ecxMsoNormal"><span style="font-size:10.5pt;font-family:Consolas;color:#1F497D;"> </span></p></div><p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;">Also Adtran SIP gateways appear not to support OPTIONS packets when running in SIP proxy mode, which is very annoying. At some point I’ll try and arrange a slugfest between Digium and Adtran and they can figure out why it doesn’t work.</span></p><p class="ecxMsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D;"> </span></p><div><div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in;"><p class="ecxMsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";"> asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] <b>On Behalf Of </b>Todd R.<br><b>Sent:</b> Monday, January 19, 2015 1:45 PM<br><b>To:</b> Asterisk-Users List<br><b>Subject:</b> Re: [asterisk-users] sip show channelstats reliable?</span></p></div></div><p class="ecxMsoNormal"> </p><div><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";">Additional info:</span></p><div><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";"> </span></p></div><div><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";">At the moment I am running 1.8.x but the other day I was getting the same results on 11.x</span></p></div><div><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";"> </span></p></div><div><p class="ecxMsoNormal"><span style="font-family:"Calibri","sans-serif";">Here is a sample from show channelstats.
