[Users] Question about the treatment of incoming messages
by Antoine Fressancourt 24 Feb '06

24 Feb '06

Hello, I have a question about the behaviour of OpenSER while treating incoming messages. This question may be a detail for most of the people here, but I think that it has an impact on the dimensioning of an OpenSER setup, especially if it is used to treat a large number of users / messages. I would like to know if Openser is able to store incoming messages in a queue when all the children launched by the program are occupied, or if the messages are rejected when no threads are available to treat them. For instance, if I launch openser with children=5 and these 5 children threads are occupied when a SIP message arrives, is the message rejected or is it stored in a FIFO queue ? In addition, I would be interested to know which part of the code is relevant to look at to deal with this issue. Thanks in advance for all your remarks and answers about my question.

[Users] Few questions about dynamic routing and load management
by Florian Fainelli 24 Feb '06

24 Feb '06

Hello all ! First of all, thank you very much for this great software it is really awesome. For the moment, I am doing static routing with config file rotation in order to have a kind of dynamic routing to voip gateways, but I would like to store my routing conditions (src_ip, forward ...) in a MySQL database, is that currently possible ? I also have another need. Is openser capable of knowing the capacity of a remote gateway it fowards the traffic to ? For instance, I have a machine sending 100+ calls, and I have several voip gateways with 32 channels, then I would like to "fill" them according to my openser incoming calls. I am not sure I am clear, but I can re-explain that if needed. Finally, is there a management tool that can show at any time the amount of calls being reached trough openser ? Thank you very much in advance for your answers and keep on the good work ! -- Cordialement, Florian Fainelli --------------------------------------------- 5, rue Charles Fourier Chambre 1511 91011 Evry http://www.alphacore.net (+33) 01 60 76 64 86 (+33) 06 09 02 64 95 --------------------------------------------- Institut National des Télécomnications http://www.int-evry.fr/telecomint ---------------------------------------------

[Users] Error when trying to lookup locations in a non local database
by Dioris Moreno 24 Feb '06

24 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" # ------------------ 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/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] Openser TLS: problem on port 5061
by Martin Petraschek 24 Feb '06

24 Feb '06

Hi all! I finally got two clients (minisip and Snom softphone) to work with openser via TLS. I was using port 5060 for TLS connections, which is non-standard. I wanted to change this behavious and make openser listen for TLS connections on port 5061, which I thought should be possible with the following configuration parameter: listen = tls:10.1.2.9:5061 After configuring the client (minisip) to use port 5061 for TLS, restarting openser and re-registering the client, I get the following error messages in the openser log: Feb 23 16:48:45 server /usr/local/sbin/openser[6011]: ERROR:tm:add_uac: can't fwd to af 2, proto 1 (no corresponding listening socket) Feb 23 16:48:45 server /usr/local/sbin/openser[6011]: ERROR:tm:t_forward_nonack: failure to add branches The ssl handshake worked without problems, which I confirmed by looking at the output of ssldump. Can anyone tell me what these error messages mean? I am using openser-1.0.0-tls. Cheers, Martin

[Serusers] SER+NAT
by Barta János 24 Feb '06

24 Feb '06

Hello! I would like to make a SIP proxy, with dual function. The first function will be a normal SIP proxy, while in the sec. function it will be working as an RTP proxy. For example: A user sends a registration reguest to my SIP. The proxy sees, that the domain name is mytest.ser, and the proxy will know, that this domain will be managed by itself. If the user creates a new registration -but in this case with mytest.hu- then the SER will do a NAT, and forwarding the message away, via the external interface (to another proxy). The arch: Client <-> DefaultGW (+SIP and RTP proxy) <-> Another SIP 10.1.1.1 <-> 10.1.1.254 __NAT___10.200.200.254 <-> 10.200.200.1 The default config -with a little modification- is working fine, but it does not rewrite the contact header in the SDP file . (I installed the rtpproxy, and I have set up iptables too.) alias=mytest.ser loadmodule "/usr/lib/ser/modules/nathelper.so" route{ #inserted by klaus if (method=="INVITE") { record_route(); force_rtp_proxy(); forward(10.200.200.1,5060); /* set up reply processing */ t_on_reply("1"); }; forward(10.200.200.1,5060); } #inserted by klaus # all incoming replies for t_onrepli-ed transactions enter here onreply_route[1] { if (status=~"[12][0-9][0-9]") force_rtp_proxy(); } A number of persons will be use it with M$ Messenger, so I'm interested in such a solution, where we do not need to set an outbound proxy in the client. Can somebody send me any example?

[Serusers] SER + Asterisk + Billing
by Jean-Michel Hiver 24 Feb '06

24 Feb '06

Hi List, I have the following setup now: <wholesale customer> -> SER -> Asterisk -> PSTN Gateway I use SER to handle all the SIP mambo-jumbo for my wholesale customers and my softphones. I use Asterisk to collect CDRs and to LCR routing. Now here is to my question: For my wholesale customers, I do IP-based "trusted host" authentication. Is there a way to set a SIP field (in SER) which will identify them uniquely in Asterisk's Master.csv file? The Asterisk records can look like this: "","anonymous","0262914900","world","""Anonymous""<anonymous>","SIP/anonymous.invalid-08160370","SIP/mygateway-7073","Dial","SIP/16170262914900@mygateway","2006-02-24 13:03:51","2006-02-24 13:04:08","2006-02-24 13:04:22",31,14,"ANSWERED","DOCUMENTATION" Any ideas?
