[Kamailio-Users] forking on URIs from DB

by Robert McGilvray

I'm trying to setup custom aliases out of a sql db that will sometimes need to fork and need some help realizing how I can assign q values and process them correctly. I'm using kam 1.5. Let's assume I query for our main support line and return 3 URIs from the db along with a separate column for the q. Sip:us-support@mycomp.com q=1.0 Sip:uk-support@mycomp.com q=1.0 Sip:in-support@mycomp.com q=0.90 Based on the values I'd want to parallel fork on the first two to send this to my UK and US support line, if that fails cancel the first two branches and route to India. Just to see if I was on the right track I tried adding them as branches using $br, which from what I understand is the only way to add branches from avps/variables. I added them by appending ;q=1.0 on the end of the URI like you would see in a Contact header but I don't think that's valid. Calls to $(branch(q) return <null> so it obviously doesn't take. If I were to just fork sequentially I could just load them into avps and call it in a failure route, but how do I handle a combination of the two? Am I wrong in trying to specify the q along with the URI? I noticed serialize_branches was removed in 1.4, which is what I use in production today in 1.3 - do I need to use the replacements in TM to order them and add the branches? Thanks in advance. -------------------------------------------------------------------------- This email with all information contained herein or attached hereto may contain confidential and/or privileged information intended for the addressee(s) only.

by Matteo Piazza

Hi to everybody, I have an issue with the nathelper module and openser 1.3.4 . Basically I want generate the Option message after the registration of a client, but the server generate a UDP message with the correct ip and port but empty. Below the openser.cfg file and as attachment a pcap file where you can see the registration message and the UDP message empty. Any clue? With the same configuration in another enviroment I don't have any issue Kind Regards Matteo # # $Id: openser.cfg 4424 2008-06-27 10:25:22Z henningw $ # # OpenSER basic configuration script # by Anca Vamanu <anca(a)voice-system.ro> # # Please refer to the Core CookBook at http://www.openser.org/dokuwiki/doku.php # for a explanation of possible statements, functions and parameters. # ####### Global Parameters ######### debug=3 log_stderror=yes log_facility=LOG_LOCAL0 fork=yes children=4 /* uncomment the following lines to enable debugging */ #debug=6 #fork=no #log_stderror=yes /* uncomment the next line to disable TCP (default on) */ #disable_tcp=yes /* uncomment the next line to enable the auto temporary blacklisting of not available destinations (default disabled) */ #disable_dns_blacklist=no /* uncomment the next line to enable IPv6 lookup after IPv4 dns lookup failures (default disabled) */ #dns_try_ipv6=yes /* uncomment the next line to disable the auto discovery of local aliases based on revers DNS on IPs (default on) */ #auto_aliases=no /* uncomment the following lines to enable TLS support (default off) */ #disable_tls = no #listen = tls:your_IP:5061 #tls_verify_server = 1 #tls_verify_client = 1 #tls_require_client_certificate = 0 #tls_method = TLSv1 #tls_certificate = "//etc/openser/tls/user/user-cert.pem" #tls_private_key = "//etc/openser/tls/user/user-privkey.pem" #tls_ca_list = "//etc/openser/tls/user/user-calist.pem" port=5060 /* uncomment and configure the following line if you want openser to bind on a specific interface/port/proto (default bind on all available) */ listen=udp:77.72.192.99:5060 alias= leo.trentinonetowrk.it ####### Modules Section ######## #set module path mpath="//lib/openser/modules/" /* uncomment next line for MySQL DB support */ loadmodule "postgres.so" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "mi_fifo.so" loadmodule "uri_db.so" loadmodule "uri.so" loadmodule "xlog.so" loadmodule "acc.so" loadmodule "auth.so" loadmodule "auth_db.so" loadmodule "alias_db.so" loadmodule "domain.so" #loadmodule "presence.so" #loadmodule "presence_xml.so" loadmodule "dialog.so" loadmodule "lcr.so" loadmodule "avpops.so" loadmodule "pdt.so" loadmodule "permissions.so" loadmodule "nathelper.so" # ----------------- setting module-specific parameters --------------- # ----- mi_fifo params ----- modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo") # ----- rr params ----- modparam("rr", "enable_full_lr", 1) modparam("rr", "append_fromtag", 1) # ---- registrar params ----- modparam("registrar", "method_filtering", 1) modparam("registrar", "max_contacts", 10) modparam("registrar", "received_avp", "$avp(s:rcv)") # ----- uri_db params ----- modparam("uri_db", "use_uri_table", 0) modparam("uri_db", "db_url", "postgres://openser:openserrw@localhost/openser") # ----- acc params ----- modparam("acc", "db_url", "postgres://openser:openserrw@localhost/openser") modparam("acc", "early_media", 1) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 0) modparam("acc", "detect_direction", 1) modparam("acc", "failed_transaction_flag", 3) #modparam("acc", "log_flag", 1) #modparam("acc", "log_missed_flag", 2) modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "db_extra", "from_uri=$fu ;

[Kamailio-Users] kamailio with sqlops fails to start if DB is down

by logivoip＠gmail.com

Hi All, First off - thank you for this module. I have configured two redundant DB sources in my kamailio confiuration. The DB's are accessed from Kamailio for redundancy pruposes. Kamailio and the primary DB are on the same hardware node. The secondary DB is on a remote host. If Kamailio is up and both MySQL DB's are up, the config works like a charm. If the primary or the secondary DB becomes unreachable while Kamailio is up, the config handles the exception and all works well. However, if any of the DB servers becomes unreachable and Kamailio is restarted, Kamailio can no longer start. Below is an excerpt from my config file: # -- sqlops params modparam("sqlops","sqlcon","pridb=>mysql://root:@localhost/db_table") modparam("sqlops","sqlcon","secdb=>mysql://root:@192.168.1.231/db_table") /var/log/messages Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:db_mysql:db_mysql_new_connection: driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:core:db_do_init: could not add connection to the pool Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:sqlops:sql_connect: failed to connect to the database [pridb] Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:core:init_mod_child: failed to initializing module sqlops, rank 1 Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:core:main_loop: init_child failed for UDP listener What is the proper way of using multiple database servers with Kamailio?
