The INVITE message is routed correctly to one of the destinations. However the subsequent ACK and the BYE messages are not sent to the destinations. I set up opensips to run only in the udp 5060 port. Then I have two identical applications: one running on port 5061 and the other on port 5062, the 3 components are running in the same server which has a single IP address: 192.168.1.195. The application is very simple: 1. Receives the INVITE, starts streaming the RTP, and sends the OK 2. When the ACK is received injects some music in the streaming 3. Waits until de BYE is received. Then stops the streaming and sends the OK. This is the configuration of the load_balancer table: mysql> select * from load_balancer; +----+----------+------------------------+-----------+------------+--------- ----+ | id | group_id | dst_uri | resources | probe_mode | description | +----+----------+------------------------+-----------+------------+--------- ----+ | 1 | 0 | sip:192.168.1.195:5061 | pstn=1 | 0 | | | 2 | 0 | sip:192.168.1.195:5062 | pstn=1 | 0 | | +----+----------+------------------------+-----------+------------+--------- ----+ I've configured only one resource in each application because I'm just testing. Finally, this is the configuration script, which is the one from the tutorial on the website: debug=3 log_facility=LOG_LOCAL6 fork=yes children=4 /* uncomment the following lines to enable debugging */ debug=6 fork=no #log_stderror=yes /* uncomment the next line to disable TCP (default on) */ disable_tcp=yes port=5060 /* uncomment and configure the following line if you want opensips to bind on a specific interface/port/proto (default bind on all available) */ listen=udp:192.168.1.195:5060 ####### Modules Section ######## #set module path mpath="/usr/local/lib/opensips/modules/" loadmodule "maxfwd.so" loadmodule "sl.so" loadmodule "db_mysql.so" loadmodule "tm.so" loadmodule "uri.so" loadmodule "rr.so" loadmodule "dialog.so" loadmodule "mi_fifo.so" loadmodule "signaling.so" loadmodule "textops.so" loadmodule "load_balancer.so" # ----------------- setting module-specific parameters --------------- # ----- mi_fifo params ----- modparam("mi_fifo", "fifo_name", "/tmp/opensips_fifo") # ----- rr params ----- # add value to ;lr param to cope with most of the UAs #modparam("rr", "enable_full_lr", 1) # do not append from tag to the RR (no need for this script) #modparam("rr", "append_fromtag", 0) modparam("rr","enable_double_rr",1) modparam("rr","append_fromtag",1) # ----- uri params ----- modparam("uri", "use_uri_table", 0) modparam("dialog", "dlg_flag", 13) modparam("dialog", "db_mode", 1) modparam("dialog", "db_url", "mysql://root:viamonte1...@localhost/opensips") modparam("load_balancer", "db_url","mysql://root:viamonte1...@localhost/opensips") ####### Routing Logic ######## # main request routing logic route{ if (!mf_process_maxfwd_header("3")) { sl_send_reply("483","looping"); exit; } if (!has_totag()) { xlog("[Redmond] Hast'n to tag\n"); # initial request record_route(); } else { # sequential request -> obey Route indication xlog("[Redmond] Has to tag\n"); loose_route(); t_relay(); exit; } # handle cancel and re-transmissions if ( is_method("CANCEL") ) { if ( t_check_trans() ) t_relay(); exit; } # from now on we have only the initial requests if (!is_method("INVITE")) { xlog("[Redmond] Not invite\n"); if ( t_check_trans() ) t_relay(); exit; #send_reply("405","Method Not Allowed"); #exit; } load_balance("0","pstn"); # LB function returns negative if no suitable destination (for requested resources) is found, # or if all destinations are full if ($retcode<0) { xlog("[Redmond] Service full\n"); sl_send_reply("500","Service full"); exit; } xlog("[Redmond] Selected destination is: $du\n"); # send it out if (!t_relay()) { sl_reply_error(); } } It seems that the route is not saved, because the To tag is sent in the ACK and BYE messages, also the logs I've added are written as expected for each message. If necesarry I can send a new email with the log attached. Please, can you help me to find what's wrong?
