ok. right now from tcpdump I can see the session progress and OK
messages are sent to the correct ip:port of my phone, but either the
phone doesn't receive it or it doesn't process it.
I assume the problem to be the headers sent by freeswitch, and perhaps
not changed appropriately by kamailio, but I'm not sure:
Call id and Cseq are the same as in RINGING, but contact header has
freeswitch's IP (on the same server as kamailio)
Contact: <sip:3@127.0.0.1:5070;transport=udp>
Could that ever work this way?
