Hi!
Yes, I started rtpproxy with "rtpproxy" in the command line. (it's in
/usr/local/bin)
Sorry, I should have sent you the ser config:
# ------------- nat helper parameters
#We will you flag 6 to mark NATed contacts
modparam("registrar", "nat_flag", 6)
# Enable NAT pinging
modparam("nathelper", "natping_interval", 60)
# Ping only contacts that are known to be
# behind NAT
modparam("nathelper", "ping_nated_only", 1)
... and at the beginning of the routing:
# special handling for NATed clients; first, nat test is
# executed: it looks for via!=received and RFC1918 addresses
# in Contact (may fail if line-folding used); also,
# the received test should, if complete, should check all
# vias for presence of received
if (nat_uac_test("3")) {
# allow RR-ed requests, as these may indicate that
# a NAT-enabled proxy takes care of it; unless it is
# a REGISTER
if (method == "REGISTER" || ! search("^Record-Route:")) {
log("LOG: Someone trying to register from private IP, rewriting\n");
# This will work only for user agents that support symmetric
# communication. We tested quite many of them and majority is
# smart smart enough to be symmetric. In some phones, like
# it takes a configuration option. With Cisco 7960, it is
# called NAT_Enable=Yes, with kphone it is called
# "symmetric media" and "symmetric signaling". (The latter
# not part of public released yet.)
fix_nated_contact(); # Rewrite contact with source IP of signalling
if (method == "INVITE") {
fix_nated_sdp("1"); # Add direction=active to SDP
};
force_rport(); # Add rport parameter to topmost Via
setflag(6); # Mark as NATed
};
};
... and at the "end":
if (isflagset(6)) {
force_rtp_proxy();
t_on_reply("1");
append_hf("P-Behind-NAT: Yes\r\n");
};
if (!t_relay()) {
sl_reply_error();
break;
};
onreply_route[1] {
if (status =~ "(183)|2[0-9][0-9]") {
fix_nated_contact();
force_rtp_proxy();
};
}
Thanks for your help!
Sebastian
