[Serusers] radius accounting, duplicate rows and missing columns

by Simone Cittadini

I've this ser installation whose purpose in life is accounting all the calls and redirecting them to asterisk, which routes them to ISDN or a h323 GSM gateway. SIP phones -> Ser -> Asterisk -> [isdn | gsm ] all the calls are "from left to right", asterisk will never see incoming stuff from the isdn/gsm channels radius has mysql as backend, the calls works well but : if the sip phone hangsup radius writes two identical lines in the radacct table, missing the AcctSessionTime value (writes '0') if the remote phone hangsup there are the same two lines and a third line with caller and called inverted, and start and stop time with the same value Can someone tell me what's wrong with my route ? or I'm missing something in radius configuration ? some columns and lines from the radacct table "RadAcctId","AcctSessionId","AcctUniqueId","UserName","AcctStartTime","AcctStopTime" #these lines inserted if the caller hangsup first 49,"e7e71b1b-70eec1ee(a)172.18.1.13","d9428a25afbfdf52","[sip number]","2005-08-10 08:54:53","2005-08-10 08:54:58" 50,"e7e71b1b-70eec1ee(a)172.18.1.13","d9428a25afbfdf52","[sip number]","2005-08-10 08:54:53","2005-08-10 08:54:58" #these if the called number hangsup 51,"72660925-e480d1a5(a)172.18.1.13","43e7c757d53c2970","[sip number]","2005-08-10 08:57:10","2005-08-10 08:57:22" 52,"72660925-e480d1a5(a)172.18.1.13","43e7c757d53c2970","[sip number]","2005-08-10 08:57:10","2005-08-10 08:57:22" 53,"72660925-e480d1a5(a)172.18.1.13","5b732c77e7e3f37d","[external number]","2005-08-10 08:57:13","2005-08-10 08:57:13" acc_radius paramethers : modparam("acc", "radius_config", "/etc/radiusclient-ng/radiusclient.conf") modparam("acc", "log_level", 2) modparam("acc", "log_fmt", "cdfimorstup") modparam("acc", "radius_flag", 1) routing configuration : # initial sanity checks if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; # registration (and authentication) if (uri==myself) { if (method=="REGISTER") { if (!radius_www_authorize("")) { www_challenge("", "0"); break; }; save("location"); break; }; lookup("aliases"); }; setflag(1); if (method=="INVITE") record_route(); rewritehost("172.18.1.11"); if (!t_relay()) { sl_reply_error(); };

[Serusers] forking with SER

by davor jovanovic

Hi all, I have a question about routing a call to GW when user isn't in location table. If I have a user with SIP address: sip:mister@no.com, and his alias in form of his business phone on office PBX: alias = 1234 can SER use number in aliases and rewrite sip:mister@no.com to <mailto:1234@no.com> 1234(a)no.com? sip:mister@no.com -> "404 Not Found" -> use aliases -> sip:1234@no.com -> t_relay -> GW -> PBX or something like that. So if someone could explain me how can I do this. Do I need some external application to do that and return PSTN number to SER? Or how can I do forking with SER? thanks

[Serusers] looping through SER-Asterisk

by Victor Alvarez

Hi, Trying to do the following: pstn->SER->asterisk (call forward)->SER->Pstn The far end rings but when you answer the call, I get an error in Asterisk: "Got SIP response 481 "Invalid CSeq Number" back from XXX.XX.XX.XX (SER). I have tried the same using two SER machines with the same result, but if I change the scenery to pstn->SER->asterisk (call forward) -> asterisk-> Pstn, it works fine! What could be wrong here? Does anybody implemented the scenery explained above? Could anybody give me a clue? Thanks a lot. Regards, Victor.

[Users] mediaproxy problem

by jayesh nambiar

hi, I did admin the other SER and that works. Thanx. Now if the request is for foreign calls I send the request from my OPENSER to a foreign SER . That SER does trust me through the source IP. We buy pstn minutes from them. Now the calls are possible when the users are with public IP and also behind NAT. But when the call is for the Cisco phone that is to be handled by the Foriegn SER it does not get established neither the rtp sesions gets established between my SER and the end called party. Can u pls suggest a particular way to handle such calls. Can u pls suggest wat might b the problem. Thanx a lot My configuration is: debug=3 fork=yes log_stderror=no listen=203.XXX.64.XX # INSERT YOUR IP ADDRESS HERE port=5060 children=4 dns=no rev_dns=no fifo="/tmp/ser_fifo" fifo_db_url="mysql://openser:openserrw@localhost/openser" loadmodule "/usr/local/lib/openser/modules/mysql.so" loadmodule "/usr/local/lib/openser/modules/sl.so" loadmodule "/usr/local/lib/openser/modules/tm.so" loadmodule "/usr/local/lib/openser/modules/rr.so" loadmodule "/usr/local/lib/openser/modules/maxfwd.so" loadmodule "/usr/local/lib/openser/modules/usrloc.so" loadmodule "/usr/local/lib/openser/modules/registrar.so" loadmodule "/usr/local/lib/openser/modules/auth.so" loadmodule "/usr/local/lib/openser/modules/auth_db.so" loadmodule "/usr/local/lib/openser/modules/uri.so" loadmodule "/usr/local/lib/openser/modules/uri_db.so" loadmodule "/usr/local/lib/openser/modules/mediaproxy.so" loadmodule "/usr/local/lib/openser/modules/nathelper.so" loadmodule "/usr/local/lib/openser/modules/textops.so" loadmodule "/usr/local/lib/openser/modules/avpops.so" loadmodule "/usr/local/lib/openser/modules/domain.so" loadmodule "/usr/local/lib/openser/modules/permissions.so" loadmodule "/usr/local/lib/openser/modules/acc.so" modparam("auth_db|permissions|uri_db|usrloc|acc", "db_url", "mysql://openser:openserrw@localhost/openser") modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("nathelper", "rtpproxy_disable", 1) modparam("nathelper", "natping_interval", 0) modparam("mediaproxy","natping_interval", 30) modparam("mediaproxy","mediaproxy_socket", "/var/run/mediaproxy.sock") modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/ser/sip-asymmetric-clients") modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/ser/rtp-asymmetric-clients") modparam("usrloc", "db_mode", 2) modparam("registrar", "nat_flag", 6) modparam("rr", "enable_full_lr", 1) modparam("tm", "fr_inv_timer", 27) modparam("tm", "fr_inv_timer_avp", "inv_timeout") modparam("permissions", "db_mode", 1) modparam("permissions", "trusted_table", "trusted") modparam("acc", "log_level", 1) modparam("acc", "log_flag", 1) modparam("acc", "db_flag", 1) route { # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops");
