[OpenSER-Users] dispatcher and auto reload of previously failed GWs
by Miroslav HOSTINSKY 17 Apr '08

17 Apr '08

Hello all, I have problem with dispatcher module in openser 1.3.1 I am not able to correctly setup scenario when failed GWs will be automatically reloaded back by openser, when they will be available. My openser.cfg: -- mpath = "/usr/lib/openser/modules" debug = 3 fork = no log_stderror = yes children = 2 check_via = no dns = off rev_dns = off port = 5060 loadmodule "maxfwd.so" loadmodule "sl.so" loadmodule "tm.so" modparam("tm", "fr_timer", 5) loadmodule "xlog.so" loadmodule "avpops.so" loadmodule "textops.so" loadmodule "dispatcher.so" modparam("dispatcher", "list_file", "/etc/openser/dispatcher.list") modparam("dispatcher", "flags", 2) modparam("dispatcher", "force_dst", 1) modparam("dispatcher", "dst_avp", "$avp(i:271)") modparam("dispatcher", "grp_avp", "$avp(i:272)") modparam("dispatcher", "cnt_avp", "$avp(i:273)") modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_interval", 5) modparam("dispatcher", "ds_ping_from", "sip:proxy@192.168.245.201") modparam("dispatcher", "ds_probing_threshhold", 3) ######################################################################## # Request route 'main' ######################################################################## route { if ( method=="INVITE" || method=="ACK" || method=="BYE" || method=="OPTIONS" ) { ds_select_dst("1","0"); t_on_failure("1"); t_relay(); exit; } } failure_route[1] { if (t_check_status("408")) { xlog("L_INFO","Marking GW as failed...\n"); ds_mark_dst(); ds_next_dst(); t_on_failure("1"); t_relay(); } else{ t_reply("501","Not Implemented"); } } -- According to dispatcher readme file, this config should be sufficient (I think :)), but there is no OPTIONS generated by openser to the failed gateways. Removing of failed GWs works perfectly for me... Could someone help what is wrong with my config? Thanks.

Hi, I am trying to configure OpenSER such that it pings its NATed clients with SIP OPTIONS packets instead of the default dummy UDP pings. But, no matter what I do, OpenSER always sends the usual UDP pings. My openser.cfg contains the following lines - sipping_bflag sipping_method sipping_from

[Serusers] Stability 2.1
by Martin Hoffmann 16 Apr '08

16 Apr '08

Hi, we have a bit of an issue with TCP handling in SER 2.0. It appears that dead connections cause the executing TCP process to hang for a short while until it figures things out. Too many such requests and processing essentially stops. Now, I understand all of this has been fixed in SER 2.1 and all our problems will go away. Question is: Will we get new ones by upgrading. Or asked differently: Is there any experience with SER 2.1 and its statbility in a real world scenario? The boxes in question are edge proxies, so there is not much processing to be done other than basic forwarding and a bit of NAT handling. Can we risk it? Best regards, Martin

Re: [OpenSER-Users] Failure route after parallel forking (was "Problem with redirection (302 Moved temporarly)")

Sorry for resuming the post.. I can't understand how to handle failure messages after parallel forking. I need a particular configuration or OpenSER must handle them the same way of a single message? I'm using OpenSER 1.2.3-tls and also using debug mode I can't see nothing special. Thanks.

[OpenSER-Users] scope of openser flags
by Hugo Koblmueller 16 Apr '08

16 Apr '08

high.*! i'm using openser v1.2 and am a bit confused about the scope of the flag. just for information about my setup: i use openser as gateway between OCSmediation server and asterisk. i learned that the message flags are transaction persistent, which means that if i set some flags while processing the INVITE request, these flags must be visible also when we process all other requests and replies in scope of the same transaction. and i also learned, that the flags which are set for INVITE are visible only when processing 100 (Trying), 180 (Ringing), and 487 (Request Cancelled). however, the flags are not visible when processing CANCEL, 200 (OK), and ACK. thats for the theory. now i have two problems: first (as i mentioned above) i experienced, that 'my' flags are not that visible as they should be. means e.g. i set flag 3 in request route and print it out in onreply_route, where it seems not to be set. see my code below: route { ... if (src_ip == 172.xx.xx.xx) { # relay request to * if (!t_relay("udp:172.xx.xx.xx:5060")) { sl_reply_error(); } } else { # relay request to OCS if (!t_relay("tcp:172.xx.xx.xx:5060")) { sl_reply_error(); } } if (method == INVITE) setsflag(3); xlog("L_INFO","$Cyb$rm: mf=$mf, bf=$bf, sf=$sf$Cxx\n"); exit; } onreply_route { xlog("L_INFO","$Cyr$rs($rr): mf=$mf, bf=$bf, sf=$sf$Cxx\n"); } the output is the following: 10(10569) INVITE: mf=0, bf=0, sf=8 7(10566) 100(Trying): mf=0, bf=0, sf=0 5(10564) 180(Ringing): mf=0, bf=0, sf=0 8(10567) 200(OK): mf=0, bf=0, sf=0 10(10569) ACK: mf=0, bf=0, sf=0 6(10565) BYE: mf=0, bf=0, sf=0 11(10570) 200(OK): mf=0, bf=0, sf=0 as you can see the flag 3 is only set, while processing the INVITE but after this is stays reset. any ideas which problem i'm facing here? my second problem is, that i need to identify the reply "200 OK" which is answered to the relayed INVITE message. as i mentioned above, this will not be covered by the flags scope anyways. Sad <http://www.voipuser.org/modules/PNphpBB2/images/smiles/icon_sad.gif> is there any possibility to have kind of (real) global variables in openser.cfg? thx & cheers -hugo

[OpenSER-Users] SIP SIMPLE - XMPP interoperability issue
by Gaoqiang Qian 16 Apr '08

16 Apr '08

Hello everyone, I have setup the openser server with the very basic default configuration. Now I have to configure my openser server to connect with a xmpp envoironment on another host with a purpose of piloting the SIP SIMPLE - XMPP IOP. So does anyone here have successful experience of configure openser to connect with XMPP on different hosts? Or could someone provide me some instruction how to configure it. Thanks a lot in advance -- Gaoqiang Qian Automation System and Technology Helsinki University Of Technology GSM: +358415058138

[OpenSER-Users] Server crash when permanent User Location is present in DB ?!
by Pascal Maugeri 16 Apr '08

Hi I've got a weird problem I do not manage to solve alone. I'm using v1.3.0 with mysql.so and and usrloc.so, on redhat enterprise v4. When there is a permanent user location in the database (added previously with openserctl ul add), the server does not start: - there is no log about any error, - after starting the server, there is no running openser process Is it a server bug or should I activate/configure something else ?
