Hi guys,
I'm trying to get this constellation running
Asterisk (priavte IP)---->SER (public IP)---->Asterisk (public IP)
I've already Asterisk set up to put the external IP to the SIP messages
with this parameter in sip.conf
externip = 82.98.89.129
but I'm not sure what I have to configure on SER. Do I need the nathelper?
My config of SER looks like this:
# ----------- global configuration parameters ------------------------
debug=4 # debug level (cmd line: -dddddddddd)
#debug=0
fork=no
log_stderror=yes # (cmd line: -E)
check_via=no # (cmd. line: -v)
dns=no # (cmd. line: -r)
rev_dns=no # (cmd. line: -R)
#listen=10.4.1.80
port=5060
children=4
fifo="/tmp/ser_fifo"
# ------------------ module loading ----------------------------------
loadmodule "/usr/local/ser/lib/ser/modules/sl.so"
loadmodule "/usr/local/ser/lib/ser/modules/tm.so"

# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
};
append_hf("P-hint: usrloc applied\r\n");
route(1);
}
route[1]
{
if (!t_relay()) {
sl_reply_error();
};
#log(1,

#sl_send_reply("180", "Ringing");
}
route[3]
{
if (uri =~ "sip:0[0-9]@*") {
log(1, "Forwarding to MG03 \n");
rewritehostport("82.98.89.176:5060");

break;

}
I appreciate any help
Thanks
