Hi List,
Phone-1 ------->Proxy1 (kamailio)-------------->Proxy-2(3rd party)
-------------> phone 2
Calls from phone-1 to phone-2, proxy-2 is sending early media without sdp in
provisional reply, this early media is sourced from different port than
response (200), what port proxy-1 will use to transmit actual voice, the
source port in early media or source port in response(200) which is
different than early media.
Thanks,
Asim
