Hi Gonzalo,
Thanks a lot for your reply. I took a closer look at the issue and I guess we
figured out the reason why this is happening. But, still couldnt get the
solution unfortunately. Our topology is like this:
sipml5(behind NAT) -> (Public Interface)kamailio(Private Interface) <---->
Freeswitch
So, when we are sending calls to to freeswitch via Kamailio; Freeswitch is
updating the SDP with its private IP. Therefore the client tries to send RTPs
to the private IP of freeswitch. We have rtpproxy installed in our Kamailio
server. We tried bunch of stuffs to solve the issue like ICE handling with
rtpengine but nothing worked out. Can you please give me some more advise that
I may try ?
Thanks in advanced.

Hi Kamrul,
Can you provide more details about the call flow:It is important to understand
the following:-Topology-Web browser models and versions (Chrome vs
FireFox)-Kamailio version
When you say:"It works perfectly within local network"
Please take a look at ICE negotiation.
I have sipml5 placing calls to Asterisk via Kamilio working without any issues.
sipml5 ---> kamailio --> fs --> asterisk ------------------ media
------------>
Please provide logs:sipml5 (java console)kamailio logs(If possible browser logs)

Please check ICE server settings. Your browser may be publishing local IP. One
way voice or no voice is typical case when client is behind firewall.

Subject: [SR-Users] One sided or no voice issue with websockets
Hi,
We have a setup with sipml5 to kamailio. It works perfectly within local
network. In public network the signaling establishes perfectly, but most of the
time we hear no voice, sometimes we hear one sided voice and in rare cases we
hear voice from both sides.
To fix this issue we configured our nathandler like the below: But, still no
luck. Any idea how to fix this? Please HELP!!!
modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)")
modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n")
.
.
.
route {
.
.
if (nat_uac_test("115")) {
if(nat_uac_test("64"))
force_rport();
}
if (method=="REGISTER") {
fix_nated_register();
add_rcv_param();
} else {
fix_nated_contact();
if(nat_uac_test("64")){
if (!add_contact_alias()) {
xlog("L_ERR", "Error aliasing contact <$ct>\n");
sl_send_reply("400", "Bad Request");
exit;
}
} else {
add_rcv_param();
}
}
}
.
.
onreply_route {
if (nat_uac_test(64)) {
add_contact_alias();
}
.
.
}
