I was taking frame 8 as a new invite. I'll see what I'm doing wrong.
No, it's a reinvite. The distinguishing feature of an in-dialog request
(aka in-dialog invite aka reinvite) is the presence of a To-tag:
To: <sip:+1callerid-did@[PSTN-IPADDRESS]:5060>;tag=gK0e4a212a
The Route headers also give it away:
Route:
<sip:[PUBLIC-KAMAILIO];lr;r2=on;ftag=gK0e4a212a;vst=AAAAABkJAw0IDQ4PAQF2AXIWFwYXGQEWHQc4OjUwNjA-;did=7.a51>
Route:
<sip:127.0.0.8;line=sr-XLSMq0lrx0hrq6lrx0lgX0dzPLkgP9dgTvDWTH2vZH1Se5CmxIuWqyTHF621E-R1E-uaZhRyxCSC-IDEEKR5xhRiZKF5F2SiD2RRKtWDiHD48SKyI.Q1fIwh8sEzemYWeIC*>
These are built from the Record-Routes in the initial INVITE transaction:
Record-Route:
<sip:[PUBLIC-KAMAILIO];r2=on;lr;ftag=gK0e4a212a;vst=AAAAABkJAw0IDQ4PAQF2AXIWFwYXGQEWHQc4OjUwNjA-;did=7.a51>
Record-Route:
<sip:127.0.0.8;line=sr-XLSMq0lrx0hrq6lrx0lgX0dzPLkgP9dgTvDWTH2vZH1Se5CmxIuWqyTHF621E-R1E-uaZhRyxCSC-IDEEKR5xhRiZKF5F2SiD2RRKtWDiHD48SKyI.Q1fIwh8sEzemYWeIC*>
It's definitely a reinvite.
