I've opened the captured traffic with Wireshark

that Kamailio is actually forwarding the call with a double SDP
header. ngrep was showing only a partial header. I think this happens
because when forwarding the call I use rtpengine_offer() and not
rtpengine_manage(). I've tried using rtpengine_manage() and I get only
one SDP header but with the (wrong) private IP address. I've tried
also rtpengine_delete() before rtpengine_offer() but there's always a
double header. Ideas? Still digging..
Duplicated SDPs in combination with rtpengine are usually the result of
manipulating the SDP multiple times, e.g. using sdpops first and then
passing the SDP to rtpengine (or the other way around) without
msg_apply_changes() in between, or perhaps invoking the rtpengine
methods multiple times within the same script run.
