[Serusers] Problem with SER accounting, Please help
by mkumar＠mantragroup.com 23 Feb '06

23 Feb '06

Hi All, I was able to install SER and able to get all the call details to the Mysql DB. But my problem is with the time of timestamp recorded, it is not recorded according to time on Server where my DB is located. The time recorded is according to timezone of the caller and so because of this when I use NOW() of Mysql and get the calls I miss the calls dialled from timezones ahead of NOW() time on Mysql. I think while inserting call details in to DB the acc.so module is using some other thing other than using NOW(). Please tell me where can I modify that query and get a common timezone for all the users so that billing will not be a problem for me. Any help will be sincerely appreciated. Thanks, Manoj.

[Users] Error when trying to lookup locations in a non local database
by Dioris Moreno 23 Feb '06

23 Feb '06

I have three sip proxies configured with OpenSER and MediaProxy for NAT traversal support, I'm going to call them Proxy A, B and C. These proxies work together as a farm; the Proxies A and C points to the MySql database installed in Proxy B. Proxy B serves as location server an also as proxy. Everything works fine, the REGISTER requests are validated against the database (installed in Proxy B) by any proxy without any problem. Also, the location records are inserted without any problem. However, I noticed when Proxies A or C receive an INVITE request, they respond 404 - User Not Found. I made a lot of debug, captures and anything else, and I found the lookup function is only getting locations for user agents registered by the Proxy that is making the query; in other words, if the user X registers through Proxy A, then an INVITE request received by Proxy A to user X is routed successfully. I don't know if I'm missing something. I'm using db_mode 1 for usrloc to store locations directly in the database. Below is one of my configuration scripts, the three are practically the same, they are different on the listen IP addresses and in the record route for nated clients. I'll appreciate any help. Thank you # ----------- global configuration parameters ------------------------ debug=9 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) # Uncomment these lines to enter debugging mode #fork=no #log_stderror=yes # check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) listen=AAA.BBB.CCC.DDD port=5060 children=4 fifo="/tmp/openser_fifo" fifo_db_url="mysql://openser:password@dbs.sip.mydomain.com/openser" #Aliases alias="sip.mydomain.com" # # uncomment the following lines for TLS support #disable_tls = 0 #listen = tls:your_IP:5061 #tls_verify = 1 #tls_require_certificate = 0 #tls_method = TLSv1 #tls_certificate = "/usr/local/etc/openser/tls/user/user-cert.pem" #tls_private_key = "/usr/local/etc/openser/tls/user/user-privkey.pem" #tls_ca_list = "/usr/local/etc/openser/tls/user/user-calist.pem" # ------------------ module loading ---------------------------------- 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/alias_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/domain.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/xlog.so" # ----------------- setting module-specific parameters --------------- modparam("usrloc|auth_db|domain|uri_db|alias_db", "db_url", "mysql://openser:password@dbs.sip.mydomain.com/openser") modparam("usrloc", "use_domain", 0) modparam("usrloc", "db_mode", 1) modparam("usrloc", "timer_interval", 60) modparam("registrar", "use_domain", 0) modparam("registrar", "nat_flag", 6) modparam("registrar", "min_expires", 10) modparam("registrar", "max_expires", 80) modparam("registrar", "default_expires", 30) modparam("rr", "enable_full_lr", 1) modparam("auth_db", "calculate_ha1", yes) 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","mediaproxy_socket", "/var/run/proxydispatcher.sock") modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/openser/sip-clie nts") modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/openser/rtp-clie nts") # ------------------------- request routing logic ------------------- # main routing logic route { # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops");

[Users] multiple rtp onsame port

Hi all,I am facing a strange problem while using openser. I am running openser 1.0.0 and while calling, multiple call gets connected on the same port. I am using Audiocodes media gatewaywhich sends calls to Openser and openser then t_relays the call to pstn gateway. When there are simultaneously 8-10 calls going on, there are more than 1 call getting connected on the same port.It is like a cross connection in which you can hear a other phone ring.I get the following log on the Audiocodes gateway:2d:5h:1m:54s Multiple RTP detected on Port 6010.

[Users] NEW FEATURE: cacheless usrloc
by Bogdan-Andrei Iancu 22 Feb '06

22 Feb '06

Hi everybody, USRLOC module can now operate in a DB mode : DB_ONLY. This is a cacheless mode - no memory cache is kept, all operation being directly done into DB. This mode allows DB sharing between multiple proxies without the need of additional replication mechanism. Drawbacks: - some performance penalties due intensive DB usage - location watcher disabled (cannot be bind to a record into mem) => PA cannot be used - statistics do not work since events cannot be properly been traced without a mem cache Still to be done: - the get_all_ucontacts function (used by nathelper/mediaproxy for NAT pinging) use raw_query in order to increase performance by filtering the loaded contacts from DB. For more info, see: http://openser.org/docs/modules/1.1.x/usrloc.html#AEN252 regards, bogdan

[Serusers] Forwarding - why append_branch() ?
by benaudi＠gmx.de 22 Feb '06

22 Feb '06

Hello, perhaps somebody can explain for me why first example works without append_branch() and second example NEED append_branch() to work? In 1. example i rewrite Request-URI in main-route-block. SER calls the new URI successfully. If i make append_branch() here, SER craches. In 2. example i rewrite Request-URI in failure-block. If i do not make append_branch() here, SER does not call the new URI. With append_branch() everything is all right, SER calls successfully the new URI. 1. example ------------------------- modparam("tm", "fr_inv_timer", 10) # set fr_inv_timer to 10 seconds ... route{ ... if (lookup("location")) { ... route(1); break; } else if (method == "INVITE" ) { revert_uri(); avp_db_load("$ruri","s:redirect_number01"); t_on_failure("2"); attr2uri("redirect_number01"); t_relay(); break; } } ------------------------- 2. example (same ser.cfg) ------------------------- failure_route[1] # entered when fr_inv_timer hits, 408 Timeout { revert_uri(); avp_db_load("$ruri","s:redirect_number01"); t_on_failure("2"); attr2uri("redirect_number01"); append_branch(); # why necessary? t_relay(); break; } } ------------------------- Alex -- Lust, ein paar Euro nebenbei zu verdienen?

RE: [Serusers] Does SER need a public IP interface?
by George Lambson 22 Feb '06

22 Feb '06

I think mediaproxy would be a better choice. It seemed to be easier to configure for me, and it does load balancing if you want it. Since your server is handling RTP and SIP when your are going through a NAT it can give you the capability to handle more than 50 calls at a time. Also, I am not sure if rtpproxy rewrites the SDP information. That would be why your phones are sending back to the internal port instead of the external one. >>> "Bart J. Smit" <bart(a)smits.co.uk> 2/18/2006 9:45:00 AM >>> No, rtpproxy. Is there a difference in NAT support? Bart... -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of George Lambson Sent: 18 February 2006 15:54 To: serusers(a)lists.iptel.org Subject: Re: [Serusers] Does SER need a public IP interface? Are you using mediaproxy? >>> "Bart J. Smit" <bart(a)smits.co.uk> 2/18/2006 7:16 AM >>> I have based my attached SER config file on the very informative 'getting started 5' instructions/sample from http://www.onsip.org/. I have SER on a DMZ with Asterisk on the same box, listening on 5065. I can register two internal phones with SER and talk. I can register a phone to the Asterisk and talk to the rest of the Asterisk infrastructure through IAX2. I entered a log statement for my forward to asterisk and I can see that it is being executed. What I can't get to work is external phones. When I capture the RTP packets with ethereal, I can see that the ones from SER to the phones are properly addressed to the public IP of my NAT-ed phone. However the return packets are addressed to the private IP of SER and thus never make it back. Is this double NAT configuration supported? It looks that way on the getting started diagrams (both SER and Internet phones are behind NAT routers). I understand that the NAT traversal mechanism in SER is there to help clients overcome their NAT. Is there a similar mechanism for the SER server itself, or does SER only work if it has a direct public interface? How do I convince my client phones to send their packets back to the public IP of SER, rather than the private IP? What ser.cfg line determines the source IP that SER gives out to the RTP stream? It would be elegant if I can make this dependent on the source IP of the phones (internal or external) but I really only need it to work for external clients, as internal ones can simply register with Asterisk. Any hints would be most appreciated, Thanks, Bart... _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
