[Serusers] Per-cent Sign in Attributes
by Martin Hoffmann 15 Sep '07

15 Sep '07

Salut, sorry for getting lazy now. In the config snipped | append_to_reply("%$digest_challenge"); what is the point of the per-cent sign in front of the attribute name? Thanks, Martin, who though he had figured all this out. Apparently not.

[OpenSER-Users] Problem with SRV lookups
by Tim Madorma 15 Sep '07

15 Sep '07

Hi, I have a simple application where I am trying to an SRV record to load balance towards a few different destination servers. I set up my DNS server to resolve to four different destination A record URIs - something like: _sip._udp.aimcidfilter.com 180 IN SRV 1 50 5061 crunch.com. _sip._udp.aimcidfilter.com 180 IN SRV 1 50 5061 spinner.com. _sip._udp.aimcidfilter.com 180 IN SRV 2 50 5061 homer.com. _sip._udp.aimcidfilter.com 180 IN SRV 2 50 5061 bart.com. In my configuration file, I am putting a domain name in my call to seturi as follows: seturi("sip:feature_fs@aimcidfilter.com:6010"); and then I call route to send the INVITE. I was expecting to see a NAPTR and SRV record attempts, but when I sniffed DNS, I only saw A record attempts. Any advice would be very helpful. thanks, Tim ------------------------------------ My configuration file looks as follows: # # TWC OpenSER SIP Proxy for Caller ID - openser_cid.cfg # # ----------- global configuration parameters ------------------------ debug=5 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) maxbuffer=1048576 check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #reply_to_via=1 children=4 log_facility=LOG_LOCAL4 dns_use_search_list=no dns_servers_no=2 # One for the ENUM server and one for other DNS lookups user="sipproxy" group="sipproxy" disable_dns_blacklist=yes # FOR TESTING ONLY dns_try_ipv6=no # FOR TESTING ONLY # Local IP Address and port to listen to # Set the following IP addresses to the value of the local e1000g0 interface listen=udp:65.185.232.62:5060 # Alias IP address/port pair values will be in the Req URI when the # OpenSER is being load balanced with a BIG IP server # Set the IP addresses to the value of the associated blade # of the BIG IP that is load balancing for the SIP Proxy server. alias=65.185.233.104:5060 # LOAD OpenSER MODULES mpath="/sw/lib/openser/modules/" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "acc.so" loadmodule "mi_fifo.so" loadmodule "xlog.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 0) # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- modparam("acc", "log_level", 2) modparam("acc", "log_flag", 1) modparam("acc","report_cancels", 1) modparam("acc","failed_transaction_flag", 1) modparam("acc","log_extra", "req_uri=$rU") modparam("tm", "fr_timer", 5) modparam("tm","fr_inv_timer",5) modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo") # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol if (!method=="REGISTER") record_route(); # subsequent messages within a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { route(1); }; if (method=="OPTIONS") { sl_send_reply("200", "OK"); exit; } if (uri =~ "^sip:feature_fs@" || method=="NOTIFY") { xlog("L_DBG", "TWC: received incoming message:\n <$mb>\n"); seturi("sip:feature_fs@aimcidfilter.com:6010"); setflag(1); route(1); } else { sl_send_reply("404", "Not Found"); }; } ##################################################### # Default Message Handler ##################################################### route[1] { # Send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; }

I'm trying to compile the trunk version. After updating I run make distclean and make exclude_modules="auth_diameter h350 ldap mi_xmlrpc osp postgres unixodbc" modules install but after I always get: make[1]: Leaving directory `/usr/local/src/VoIP/openser/openser/trunk/modules/auth_db' make: *** [modules] Error 2 What is this "Error 2" ? In this same machine I can compile, without a glance, branche 1.2 with this same 'make' command. Thanks for any help.... Edson

[OpenSER-Users] registration and redirection
by Mike Clark 14 Sep '07

14 Sep '07

Ok, I am brand new to openser and don't really have ti routing anything yet. But I did have a dumb or at least naive question. Can openser be configured as a very simple load balancer and redirect registration requests, in a round robin manner, to a set of Asterisk servers? I know having openser be the registrar is the best solution in the long run, but this may solve an issue quickly. I looked at the dispatch module and I know it will do want I want for invites, but didn't know if registration requests could be redirected. Thanks, Mike Clark

[Serusers] SER+Mediaproxy + X-LITE in the same LAN.
by pistara_bros＠tin.it 14 Sep '07

14 Sep '07

Hi all, i'm newbie in SER, I want to route RTP packets between 2 computers with x-lite client voip in the same network through Mediaproxy. I know this may have no sense, but it's just a test configuration. The call use_media_proxy() seems to have no effect, the RTP packets go directly from one computer to another, no packet trough Mediaproxy. This is my environment: SER and Mediaproxy on the same PC (192.168.123.186) X-lite client_A running on 192.168.123.10 X-lite client_B running on 192.168.123.168 Client_A call Client_B that accept, but mediaproxy refuses to proxy the call.

[OpenSER-Users] domain name in route header
by jh＠tutpro.com 14 Sep '07

14 Sep '07

klaus, if you want to support domains in route headers, then you need to do naptr and srv lookups for the domain when handling loose routing. it is not enough to compare the domain to the ones domain module knows about. domain in route header may namely be anything as long as it resolves to your proxy. for this reason, i don't like the idea of domains in route headers. it hurts performance far too much. -- juha

by Dawid Jarosławski 14 Sep '07

14 Sep '07

Hello, I'm trying to make outbound proxy for my network using OpenSER. Currently I've configured OpenSER as sip registrar/rtpproxy and it works fine even with NAT traversal. The problem is that I don't how shuould I reconfigure my config to make it work as outbound proxy. I've tried many changes with no results. The first problem is how to correctly handle the register method. My config is based on: http://siprouter.onsip.org/doc/gettingstarted/ch08s02.html Can anyone help me? Best regards, Dawid Jaroslawski
