Hello,

I have been unsuccessfully trying to setup OpenSER as a basic server in my private network. The idea is that clients can register to the virtual domain “sipserver.apt.local” and from then, INVITES will be sent to the appropiate address.

I use the following openser.cfg

# ----------- global configuration parameters ------------------------

debug=5 # debug level (cmd line: -dddddddddd)

fork=yes

log_stderror=no # (cmd line: -E)

children=4

log_facility=LOG_LOCAL7

# Uncomment these lines to enter debugging mode

#fork=no

#log_stderror=yes

port=5060

listen=udp:192.168.100.244:5060

listen=udp:sipserver.apt.local:5060

alias="sipserver.apt.local:5060"

sip_warning=yes

# uncomment the following lines for TLS support

#disable_tls = 0

#listen = tls:your_IP:5061

#tls_verify_server = 1

#tls_verify_client = 1

#tls_require_client_certificate = 0

#tls_method = TLSv1

#tls_certificate = "/etc/openser/tls/user/user-cert.pem"

#tls_private_key = "/etc/openser/tls/user/user-privkey.pem"

#tls_ca_list = "/etc/openser/tls/user/user-calist.pem"

# ------------------ module loading ----------------------------------

#set module path

mpath="/usr/lib/openser/modules/"

# Uncomment this if you want to use SQL database

#loadmodule "mysql.so"

loadmodule "sl.so"

loadmodule "tm.so"

loadmodule "rr.so"

loadmodule "maxfwd.so"

loadmodule "usrloc.so"

loadmodule "registrar.so"

loadmodule "textops.so"

loadmodule "mi_fifo.so"

loadmodule "xlog.so"

# Uncomment this if you want digest authentication

# mysql.so must be loaded !

#loadmodule "auth.so"

#loadmodule "auth_db.so"

# ----------------- setting module-specific parameters ---------------

# -- mi_fifo params --

modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo")

# -- usrloc params --

modparam("usrloc", "db_mode", 0)

# Uncomment this if you want to use SQL database

# for persistent storage and comment the previous line

#modparam("usrloc", "db_mode", 2)

# -- auth params --

# Uncomment if you are using auth module

#modparam("auth_db", "calculate_ha1", yes)

# If you set "calculate_ha1" parameter to yes (which true in this config),

# uncomment also the following parameter)

#modparam("auth_db", "password_column", "password")

# -- rr params --

# add value to ;lr param to make some broken UAs happy

modparam("rr", "enable_full_lr", 1)

# ------------------------- request routing logic -------------------

# main routing logic

route{

# initial sanity checks -- messages with

# max_forwards==0, or excessively long requests

if (!mf_process_maxfwd_header("10")) {

sl_send_reply("483","Too Many Hops");

exit;

};

if (msg:len >= max_len ) {

sl_send_reply("513", "Message too big");

exit;

};

# we record-route all messages -- to make sure that

# subsequent messages will go through our proxy; that's

# particularly good if upstream and downstream entities

# use different transport protocol

if (!method=="REGISTER")

record_route();

# subsequent messages withing a dialog should take the

# path determined by record-routing

if (loose_route()) {

# mark routing logic in request

append_hf("P-hint: rr-enforced\r\n");

route(1);

};

if (!uri==myself) {

# mark routing logic in request

append_hf("P-hint: outbound\r\n");

# if you have some interdomain connections via TLS

#if(uri=~"@tls_domain1.net") {

# t_relay("tls:domain1.net");

# exit;

#} else if(uri=~"@tls_domain2.net") {

# t_relay("tls:domain2.net");

# exit;

route(1);

};

# if the request is for other domain use UsrLoc

# (in case, it does not work, use the following command

# with proper names and addresses in it)

if (uri==myself) {

if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication

#if (!www_authorize("openser.org", "subscriber")) {

# www_challenge("openser.org", "0");

# exit;

#};

xlog("L_INFO","[ACHTUNG] saved $ru");

save("location");

exit;

};

xlog("L_INFO","[ACHTUNG]request from $ru");

#lookup("aliases");

#if (!uri==myself) {

# append_hf("P-hint: outbound alias\r\n");

# route(1);

#};

# native SIP destinations are handled using our USRLOC DB

#if (!lookup("location")) {

# sl_send_reply("404", "Not Found");

# exit;

#};

#append_hf("P-hint: usrloc applied\r\n");

};

route(1);

}

route[1] {

# send it out now; use stateful forwarding as it works reliably

# even for UDP2TCP

if (!t_relay()) {

sl_reply_error();

};

exit;

}

I can register fine, however, on INVITE, openSER forwards it internally instead of fw to the client registered until max_fw reaches 0 and an error “too many hops” is the final response. Log below:

What is necessary so the INVITES are sent to the client and not to the server?
