[Kamailio-Users] Dealing with REGISTER "retransmissions"
by mayamatakeshi 25 Mar '09

25 Mar '09

Hello, we are running kamailio 1.4. Some days ago one of our subscribers SIP phone went crazy and bombarded our proxy with thousands of REGISTER requests. Actually, it didn't wait for any response of the proxy, it just kept sending REGISTER messages (same packet always). Since we are running with nonce_reuse disabled, it stalled the server due to "auth:challenge: failed to generate nonce". I don't have the whole figure but the packet capture I inspected showed that the terminal sent more than 200 thousand REGISTER messages in 15 seconds. We may not be able to replace those terminals at this moment. So to avoid this problem to happen again, we enabled nonce_reuse. However this only will solve the nonce problem but still we will have a lot of hits to database. So I was thinking, maybe I should create a transaction before sending the challenge so that REGISTER retransmissions would be absorbed. I was thinking in doing something like this: if (!proxy_authorize("", "subscriber")) { t_newtran(); proxy_challenge("", "0"); exit; } Does anyone see any problem/shortcoming with this? regards, takeshi

[Kamailio-Users] xcap and pua modules
by Luntras Loredana 25 Mar '09

25 Mar '09

Hello, I am still trying to install a presence server and a RLS. What I understood is that I have to install the xcap module on Kamailio and a Xcap server. I began with the pua and xcap_client module. When installing xcap_client I have the following errors: xcap_client.c:162: attention : implicit declaration of function «curl_global_cleanup" make[1]: *** [xcap_client.o] Erreur 1 make[1]: quittant le répertoire « /opt/kamailio-1.5.0-tls/modules/xcap_client » make: *** [modules] Erreur 2 And when I am restarting kamailio server (I've added "loadmodule pua.so) I also have an error (I am in the debug mode) Mar 25 10:12:48 [11907] ERROR:core:db_check_table_version: invalid version 5 for table pua found, expected 6 (check table structure and table "version") Mar 25 10:12:48 [11907] ERROR:pua:mod_init: error during table version check. Mar 25 10:12:48 [11907] ERROR:core:init_mod: failed to initialize module pua Mar 25 10:12:48 [11907] ERROR:core:main: error while initializing modules I have kailio 1.5. Thanks for your help, Loredana

[Kamailio-Users] New Error - Anyone Point me in the direction of what might cause this?
by Geoffrey Mina 25 Mar '09

25 Mar '09

Hello, I have a couple instances of the following error in my logs. I am not sure where to start here. ERROR:core:udp_send: sendto(sock,0x2ac741ab2828,999,0,0x2ac741ab0e50,16): Invalid argument(22) CRITICAL:core:udp_send: invalid sendtoparameters one possible reason is the server is bound to localhost and attempts to send to the net ERROR:tm:msg_send: udp_send failed ERROR:tm:t_forward_nonack: sending request failed The system is being used for two things. 1 - a PSTN routing engine using the LCR module. I have two gateways in the same group with the same weight, so I suppose I am just doing round-robin load balancing on the two. 2 - a SIP proxy where I send INVITE to the Kamailio server with a Route header set with a fully qualified SIP URI. I am not sure which of these two scenarios could cause this issue... mostly because I don't really know what I am looking at. Please note, this system processed about 25,000+ successful outbound calls today, and this error only cropped up 3 times in the logs. Thanks! Geoff

[Serusers] about SER load balance
by 静于 25 Mar '09

25 Mar '09

hi~ I wonder is there any load balance sheme used by SER? If there are multiple servers responsible for a domain. One is used as main server. Suppose main server is full weight load. To which server the main server decides to relay? ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/

[Kamailio-Users] Using OpenSer as presence server, with OpenIMS and UCT client
by Luntras Loredana 24 Mar '09

24 Mar '09

Hello all, I have a new problem. I am using Open SER (1.3.3 tls) as a presence server with an Open IMS Core. On the event presence, the OpenIMS server redirects to OpenSER. I am also using UCTImsclient for testing. The registration is ok, the messages also. The problem is the presence: it works once and after that it doesn't work all the day. Have anyone tested all theses? Thanks for your help, Loredana

[Serusers] lookup_contacts with IP's and URL's

Thanks Martin. I saved the current UA's from ser.credentials, then using ser_ctl removed them and the domain. I added the domain plus the URL as an alias and recreated the UA's using ser_ctl. Everything now works great. Thanks again! Bill

[Kamailio-Users] [dialog module] set_dlg_profile() not working?
by Iñaki Baz Castillo 24 Mar '09

24 Mar '09

Hi, perhaps I miss something but I don't get set_dlg_profile() working: ---------------- modparam("dialog", "dlg_flag", FLAG_DIALOG) modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "db_mode", 1) modparam("dialog", "profiles_no_value", "inbound ; outbound") if is_method("INVITE") { setflag(FLAG_DIALOG); set_dlg_profile("outbound"); ... ---------------- But when I run "kamctl fifo profile_list_dlgs outbound" I see nothing (the dialog does appear listed in "kamctl fifo dlg_list"). I've also added into the loose_route section: if (is_in_profile("outbound")) { xlog("L_CRIT", "*** this request belongs to an outbound call\n"); } This should appear when the ACK-200 arrives, also in any re-INVITE or BYE, but it doesn't ¿? Do I miss something? Thanks. -- Iñaki Baz Castillo
