[SR-Users] force_rtp_proxy[flag, ipaddress] not rewriting c and o ?

[MingHon]

Hello,

I also tried rtpproxy_offer/rtpproxy_answer but no luck.

my rtpproxy is running..

rtpproxy -l 192.168.2.3 -l 127.0.0.1:7722 -u user

and kamailio on 192.168.2.3 asterisk on 192.168.2.23

all three in behind same nat 175.136.223.112.

and uac is behind another nat.

below is my wireshark INVITE and 200OK.

route[RTPPROXY] { #!ifdef WITH_NAT if (is_method("BYE")) {
unforce_rtp_proxy(); } else if (is_method("INVITE")){
rtpproxy_offer("rco","175.136.223.112"); xlog("offer"); } if (!has_totag())
add_rr_param(";nat=yes"); #!endif

onreply_route[REPLY_ONE] {
        xdbg("incoming reply\n");
#!ifdef WITH_NAT
        if ((isflagset(FLT_NATS) || isbflagset(FLB_NATB))
                        && status=~"(183)|(2[0-9][0-9])") {
                rtpproxy_answer("rco","175.136.223.112");
                xlog("answer");
        }
        if (isbflagset("6")) {
                fix_nated_contact();
        }
#!endif
