I'm trying to use the LCR module to do a failover between two gateways. For testing purposes, I have a gateway record pointed at an IP that isn't used. The problem is, I can't seem to get OpenSER to fail over to the other gateway. I want to use TCP (with TLS when I'm done), but I get this: Jul 20 15:36:57 asiago /usr/sbin/openser[11896]: route[6]: routing to INVITE sip:MYDID@MYIPADDRESS:5060;transport=tcp Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR: tcp_blocking_connect: timeout (10) Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR: tcpconn_connect: tcp_blocking_connect failed Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR: tcp_send: connect failed Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: msg_send: ERROR: tcp_send failed Jul 20 15:37:17 asiago /usr/sbin/openser[11896]: ERROR:tm:t_forward_nonack: sending request failed (IP and username censored.) OpenSER sends this to the caller: SIP/2.0 477 Unfortunately error on sending to next hop occurred (477/TM) Why can't I catch this with either the return code from t_relay or the failure route? It will go to the failure route if I get a reply back from the next hop. But I need to fail to the other gateway. The relevent parts of the configs are shown below. (Addresses censored.) Any help would greatly appreciated. Thanks, ---Nathan Config snippet: # ok, so maybe try a gateway... if( load_gws() ) { xlog("L_INFO","route[3]: gateway routing $rm $ru"); t_on_failure("1"); route(6); return; } } route[6] { xlog("L_INFO","route[6]: $rm $ru"); t_on_failure("1"); t_on_reply("1"); if (!next_gw()) { xlog("L_INFO","route[6]: no more gateways for $ru"); exit; } xlog("L_INFO","route[6]: routing to $rm $ru"); if(!t_relay()) { xlog("L_INFO","route[6]: t_relay returned $rc"); sl_reply_error(); } return; } failure_route[1] { xlog("L_INFO","failure_route[1]: $rm $ru"); t_on_failure("1"); if(t_check_status("404")) { xlog("L_INFO","failure_route[1]: failing call with 404 for $ru"); return; } if (!next_gw()) { xlog("L_INFO","route[6]: no more gateways for $ru"); exit; } append_branch(); xlog("L_INFO","failure_route[1]: sending $rm $ru"); if(!t_relay()) { xlog("L_INFO","route[6]: t_relay returned $rc"); } return; } Gateways: mysql> select * from gw where grp_id=4; +---------+--------+-----------+------+------------+-----------+--------+ | gw_name | grp_id | ip_addr | port | uri_scheme | transport | prefix | +---------+--------+-----------+------+------------+-----------+--------+ | ithaka | 4 | CENSORED | 5060 | NULL | 2 | NULL | | larink | 4 | BAD_ADDRESS | 5060 | NULL | 2 | NULL | +---------+--------+-----------+------+------------+-----------+--------+ 2 rows in set (0.00 sec) ithaka is a working OpenSER proxy. larink is an empty IP address.

[Users] fail to listen on two addresses

by Jeremie Le Hen

Hi list, I am new two OpenSER. I installed OpenSER 1.1.0-notls and I need it to listen on both 127.0.0.1 and one of my physical interface's IP address. The manual page states: % -l address Listens on the specified address/interface. Multiple -l % mean listening on multiple addresses. The address format is % [proto:]address[:port], where proto = udp|tcp and address = % host|ip_address|interface_name. Example: -l localhost, -l % udp:127.0.0.1:5080, -l eth0:5062. The default behaviour is % to listen on all the ipv4 interfaces. I tried the following command-line, without success. I cannot connect to either one of the IP address I specified, depending on the order I provided them : % openser -u voipproxy -g voipproxy -l 84.xxx.xxx.xxx -l 127.0.0.1 -D -E And in another terminal: % # lsof -nPi4 -ap `pgrep -d, openser` % COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME % openser 30837 voipproxy 5u IPv4 60272 UDP 84.xxx.xxx.xxx:5060 % openser 30838 voipproxy 5u IPv4 60272 UDP 84.xxx.xxx.xxx:5060 % openser 30839 voipproxy 5u IPv4 60272 UDP 84.xxx.xxx.xxx:5060 If I turn the command-line to: % openser -u voipproxy -g voipproxy -l 127.0.0.1 -l 84.xxx.xxx.xxx -D -E I get: % # lsof -nPi4 -ap `pgrep -d, openser` % COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME % openser 30845 voipproxy 5u IPv4 60382 UDP 127.0.0.1:5060 % openser 30846 voipproxy 5u IPv4 60382 UDP 127.0.0.1:5060 % openser 30847 voipproxy 5u IPv4 60382 UDP 127.0.0.1:5060 Note that in both case I get: % Listening on % udp: 84.xxx.xxx.xxx [84.xxx.xxx.xxx]:5060 % udp: 127.0.0.1 [127.0.0.1]:5060 % tcp: 84.xxx.xxx.xxx [84.xxx.xxx.xxx]:5060 % tcp: 127.0.0.1 [127.0.0.1]:5060 Except the order change, following the command-line. I could have missed something and would be glad if someone pointed it out to me. Thank you. Regards, -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >

[Users] Q:ABOUT:MODULE:UsrLoc

by Alejandro Sanchez

Hi everybody. I have the next enviroment. OpenSer 1.1.X MySQL 5.0 Linux Fedora 4 Architecture: We have 4 servers one of them work like a LoadBalancer (openser proxy dispatcher), behind of it are the others 2 servers (openser) that have the function to kept the sessions, register, etc... they have the parameter in dbmode to 3 for kept out the cache system and the last is the MySQL DB that share the 2 sip servers. The problem is that, when a phone register it the other server delete the register in table location like if it detect that the register expires. Anybody have an idea of this type of performence?

[Users] auth_db and avps

by Andreas Granig

Hi, While authorizing a user, auth_db only loads additional AVPs on success. IMO it would also make sense to load them on failure, so you could easily check if it's a known user with wrong credentials or an unknown user. It would especially be useful for fetching the uuid of the user although authorization fails. Any comments? Andy
