Re: [Users] Problem with avp_check

Hi Jose, I think your regexp is not correct - you need to force the end of string, otherwise only a substring (prefix) will be matched. try avp_check("$fU","re/^[0-9]{10}$/g") regards, bogdan Jose Gil Navarrete wrote: > Hi thanks Andrei, I tried with your recomendation but I obtain the > same result, if $fu is: 012345678901, then "To-username > -012345678901-" is inserted > > if(avp_check("$fU","re/^[0-9]{10}/g")) { > insert_hf("To-username: -$rU- \r\n", "Call-ID"); > } else { > sl_send_reply("400", "Peticion Erronea, numero > invalido"); > }; > > > */Bogdan-Andrei Iancu <bogdan(a)voice-system.ro>/* escribió: > > Hi Jose, > > the FM operator in avp_check is not for regular expressions - FM is a > file matching- like operator (like "sip:*@domain).

[Users] OpenSER as load balancer for several Asterisk servers
by Edoardo Serra 21 Dec '06

21 Dec '06

Hi guys, I'm having a problem with an OpenSER acting as registrar server and load balancer for many Asterisk servers. In a few words: "users are registering on openser and, when they want to make a call, OpenSER proxies the request to an Asterisk server with the dispatcher module" Here is the intended data flow (SIP goes through OpenSER and media goes directly to Asterisk) User <-- SIP --> OpenSER <-- SIP --> Asterisk User <-- RTP --> Asterisk Both, OpenSER and Asterisks have public IPs I already have a working setup of that and everything seems working correctly. I'm trying to replicate that setup on another site, same configurations of the boxes, same versions of OpenSER and Asterisk, etc... but I'm having monodirectional Audio. Having a look with tethereal I see that OpenSER, when the communication is answered, sends a SIP packet (200 OK) to the user indicating itself as media endpoint instead of the Asterisks. From that moment I see RTP packets flowing from the client to OpenSER This seems really strange to me because I just copied the same configurations file from a working setup to the new installation. Tnx in advance for help. Regards P.S.: Here is my openser.cfg ## $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ ## simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) fork=yes #log_stderror=no # (cmd line: -E) check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #children=4 #port=5060 fifo="/tmp/ser_fifo" #uid=nobody #gid=nobody # ------------------ module loading ---------------------------------- loadmodule "/usr/lib/openser/modules/sl.so" loadmodule "/usr/lib/openser/modules/tm.so" loadmodule "/usr/lib/openser/modules/rr.so" loadmodule "/usr/lib/openser/modules/maxfwd.so" loadmodule "/usr/lib/openser/modules/usrloc.so" loadmodule "/usr/lib/openser/modules/registrar.so" loadmodule "/usr/lib/openser/modules/nathelper.so" loadmodule "/usr/lib/openser/modules/textops.so" loadmodule "/usr/lib/openser/modules/exec.so" loadmodule "/usr/lib/openser/modules/uri.so" loadmodule "/usr/lib/openser/modules/uri_db.so" loadmodule "/usr/lib/openser/modules/dispatcher.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/lib/openser/modules/mysql.so" loadmodule "/usr/lib/openser/modules/auth.so" loadmodule "/usr/lib/openser/modules/auth_db.so" modparam("usrloc", "db_mode", 2) modparam("usrloc", "db_url", "mysql://xxx:xxx@xxx.xxx.xxx.xxx/openser") modparam("usrloc", "timer_interval", 120) modparam("auth_db", "calculate_ha1", 0) modparam("auth_db", "db_url", "mysql://xxx:xxx@xxx.xxx.xxx.xxx/voip") modparam("uri_db", "db_url", "mysql://xxx:xxx@xxx.xxx.xxx.xxx/openser") modparam("rr", "enable_full_lr", 1) modparam("registrar", "nat_flag", 6) modparam("registrar", "max_expires", 3600) modparam("registrar", "min_expires", 60) modparam("registrar", "append_branches", 0) modparam("registrar", "desc_time_order", 1) modparam("nathelper", "natping_interval", 20) # Ping interval 20 s modparam("nathelper", "ping_nated_only", 1) # Ping only clients behind NAT modparam("dispatcher", "force_dst", 1) # ------------------------- request routing logic ------------------- # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); exit; }; if ( (method=="OPTIONS") || (method=="SUBSCRIBE") || (method=="NOTIFY") ) { sl_send_reply("405", "Method Not Allowed"); exit; } if (!method=="REGISTER") { record_route(); }; if ((src_ip==xxx.xxx.xxx.xxx) || (src_ip==xxx.xxx.xxx.xxx)) { # IP of Asterisks if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); }; exit; }; if (nat_uac_test("3")) { if ((method=="REGISTER") || (method=="INVITE") || (method=="OPTIONS")) { fix_nated_contact(); force_rport(); setflag(6); # Mark as NATed } } # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (method=="REGISTER") { if (!proxy_authorize("domain", "openser_view")) { proxy_challenge("domain", "0"); exit; } if (!check_to()) { sl_send_reply("403", "Digest username and URI username do NOT match!

[Serusers] Multiple domain
by TZieleniewski 21 Dec '06

21 Dec '06

Hi ! A have a small technical question:) It considers serving of multiple domain. I would like to make sure that I understand things right. After I read the user doc and README from domain module I came to the following state of art:) 1)one has to create the seperate location and subscriber table for each domain *so if i have for instance two domains : dom1.com and dom2.com then my ser has to have the according dns records in the dns server? 2) after creating the tables i need to add domains record in the database to the domain table *I dont know why but when ever i try to add or show domains o get the following error 500 command 'domain_dump' not available - why is that so? any way instead of an error the serctl command adds the domain record to the database 3) modify the ser.cfg file - add appropriate modparam commands 4) modify the ser.cfg file by adding a regular expression analizys to invoke the save, www_chalenge, proxy_chalenge and lookup correctly with the right domain? Please tell me is my thinking here right? or maybe there is another way As allway thank u for your time. Bests tomek

Re: [Users] Delayed signalling?
by Jiri Kuthan 21 Dec '06

21 Dec '06

if you happen to have a PCAP file with the incident, let me please know. -jiri p.s. even if you didn't tweak timers, the results may be suboptimal because the software version you are using is having rather indeterministic timer subsystem. For example, the recent measurements (http://www.iptel.org/ser/doc/performance) show quite scattered server responsiveness under high load. (Note though that the measurement results were achieved in a best-effort manner based on the tester knowledge and understanding of openser and that the result are not officially confirmed by the OpenSER project.) Whether it is indeed the cause is not certain though -- this looks really like a stealth bug. At 15:58 15/12/2006, Max Gregorian wrote: >Thanks very much for all the replies.

Ping from the server itself TTL=64 and ping times are low as you would expect (< 1ms when pinging from the server itself).

[Users] Problem with avp_check
by Jose Gil Navarrete 21 Dec '06

21 Dec '06

Hi I try to check the username in the URI, this is, if the username do not have ten digits then send a message, I made: avp_write("^[0-9]{10}","$avp(s:fm_avp)"); if(avp_check("$fU","fm/$avp(s:fm_avp)/g")) { insert_hf("To-username: -$fU- \r\n", "Call-ID"); } else { sl_send_reply("400", "Bad Request"); exit; }; but I ever obtain 400 message. I try too with: if(avp_check("$fU","re/[0-9]{10}$/g")) { insert_hf("To-username: -$fU- \r\n", "Call-ID"); else{ sl_send_reply("400", "Bad request"); exit; } But I obtain the same message. Any idea? __________________________________________________ Correo Yahoo! Espacio para todos tus mensajes, antivirus y antispam ¡gratis! Regístrate ya - http://correo.yahoo.com.mx/

[Users] A question about cancels..
by nick 21 Dec '06

21 Dec '06

When I make a call to someone, a call which is correctly connected, for example via PSTN gateway, I can watch INVITEs, ACKs, OKs and BYEs being relayed from my station the my openser to the gateway, and back.. However if the phone rings, and I decide to terminate the call (before the other person responds), I see the CANCEL going from my station to the sipserver, but I don't see it being sent to the PSTN gateway.. Is this something I have to specifically route for? The CANCEL is part of the same call sequence, is there a reason it wouldn't be relayed, other than a mistake in my routing, obviously.. Nick
