You've successfully captured the SIP call leg between your phone and your FreeSWITCH. That's good, but it's incomplete. You really want SIP and RTP both, and you want the call leg between FreeSWITCH and the telco. You have a few options:<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>Expand your tcpdump. In other words, cast a wider net. Pro: easy to do. Con: creates massive pcap files through which you must sift to find the call in question.<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>Use pcapsipdump. Pro: does all the work for you by putting SIP and RTP for each call leg into a single file. Cons: You have to compile it yourself, and it creates a whole lot of files, so you'll need to get used to it.<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>My personal opinion is this: if you never, ever have to debug a SIP call ever again then just use tcpdump. However, if you're the phone guy and you'll be doing this again in the future then bite the bullet and learn pcapsipdump. Believe me it's worth it.<o:p></o:p></p></div><p class=MsoNormal>-MC<o:p></o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'><o:p> </o:p></p><div><p class=MsoNormal>On Thu, May 16, 2013 at 3:31 PM, Sean Devoy <<a href="mailto:sdevoy@bizfocused.com" target="_blank">sdevoy@bizfocused.com</a>> wrote:<o:p></o:p></p><div><p class=MsoNormal><img border=0 width=31 height=31 id="_x0000_i1025" src="cid:image001.gif@01CE5283.81116F80"><o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'>Hi all,</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'>First, I am on version: FreeSWITCH Version 1.2.5.3+git~20121219T035317Z~2b4aa48049 (git 2b4aa48 2012-12-19 03:53:17Z) I hope to move to the Stable 1.2.9 this weekend.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='color:#1F497D'>I am having very reliable one way audio when calling Sprint Cell Phone users, though not every time.
