I am trying to configure opensips as load-balancer for freeswitch by following below link but the procedure written there seems very old and many issues are faced while following the steps mentioned in it.
https://freeswitch.org/confluence/display/FREESWITCH/Enterprise+deployment+OpenSIPS
Can someone please share some exact configuration example for this scenario which I can follow at latest ubuntu releases. Thanks
We can use opensips or kamailio as a sip loadbalancer and for high availability services in several ways based on availability of resources. I wrote a step by step guide here
Install openSIPS :
Follow this guide to install openSIPS 2.4 and use below configuration to edit opensips.cfg .
if you are not configuring high availability and hosting mysql database locally on openSIPS only , then you may want to use localhost or 127.0.0.1
and also change database credentials and SIP listening address .
vi /etc/opensips/opensips.cfg
log_level=4
sip_warning=0
log_stderror=no
log_facility=LOG_LOCAL2
log_name="opensips"
debug_mode=yes
children=4
dns_try_ipv6=no
auto_aliases=no
#advertised_address="12.135.59.0"
mhomed=1
listen=udp:10.128.0.1:5060
mpath="/usr/lib64/opensips/modules"
loadmodule "db_mysql.so"
loadmodule "signaling.so"
loadmodule "sl.so"
loadmodule "tm.so"
loadmodule "rr.so"
loadmodule "uri.so"
loadmodule "dialog.so"
loadmodule "maxfwd.so"
loadmodule "textops.so"
loadmodule "mi_fifo.so"
loadmodule "dispatcher.so"
loadmodule "load_balancer.so"
loadmodule "sipmsgops.so"
loadmodule "proto_udp.so"
modparam("mi_fifo", "fifo_name", "/tmp/opensips_fifo")
modparam("dialog", "db_mode", 1)
#change database credentials below
#if this is the only openSIPS node in network and you are using HighAvailability use mysql database host as localhost or 127.0.0.1
modparam("dialog", "db_url", "mysql://abc:[email protected]/opensips") modparam("rr", "enable_double_rr", 0)
modparam("rr", "append_fromtag", 1)
modparam("tm", "fr_timer", 2)
#change database credentials below
modparam("dispatcher", "db_url", "mysql://abc:[email protected]/opensips")
modparam("dispatcher", "ds_ping_method", "OPTIONS")
modparam("dispatcher", "ds_ping_interval", 5)
modparam("dispatcher", "ds_probing_threshhold", 2)
modparam("dispatcher", "ds_probing_mode", 1)
modparam("load_balancer", "db_url", "mysql://abc:[email protected]/opensips")
modparam("load_balancer", "probing_method", "OPTIONS")
modparam("load_balancer", "probing_interval", 5)
route{
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
exit;
}
if (!has_totag()) {
record_route();
}
else {
loose_route();
t_relay();
exit;
}
if (is_method("CANCEL")) {
if (t_check_trans())
t_relay();
exit;
}
if (is_method("INVITE")) {
if (!load_balance("1","pstn","1")) {
log("sreekanth invite method\n");
send_reply("503","Service Unavailable");
exit;
}
}
else if (is_method("REGISTER")) {
if (!ds_select_dst("1", "4")) {
send_reply("503","Service Unavailable");
exit;
}
}
else {
send_reply("405","Method Not Allowed");
exit;
}
if (!t_relay()) {
sl_reply_error();
}
}
Now we need to insert entries in loadbalance and dispatch tables of opensips database
INSERT INTO opensips.load_balancer (id, group_id, dst_uri, resources, probe_mode, description) VALUES ('1', '1','sip:10.10.10.5 ','vm=100;conf=100;transc=100;pstn=500', '1','FS1');
INSERT INTO opensips.load_balancer (id, group_id, dst_uri, resources, probe_mode, description) VALUES ('2', '1','sip:10.10.10.4 ','vm=100;conf=100;transc=100;pstn=500', '1','FS2');
and insert records in dispatcher table as well .
INSERT INTO opensips.dispatcher (id, setid, destination, socket, state, weight, priority, attrs, description) VALUES ('1', '1','sip:10.10.10.5:5060','','0', '1', '1','','FS1');
INSERT INTO opensips.dispatcher (id, setid, destination, socket, state, weight, priority, attrs, description) VALUES ('1', '1','sip:10.10.10.4:5060','','0', '1', '1','','FS2');
Configure Freeswitch :
In freeswitch /etc/freeswitch/vars.xml change domain to opensips domain name . And reload freeswitch
