[OpenSER-Users] Saving public IP in CDR
by Andreas Sikkema 14 Aug '07

14 Aug '07

Hi, I'm trying to do add accounting to our OpenSER server. Getting accounting to work is easy but I'm having trouble saving client IP addresses with every CDR. Most of our SIP UAs are behind some form of NAT and to "prove" that calls have originated at the client I want to save the public IP address and as extra service also the private IP address of the UA. Saving the private IP address is easy, $Ri contains this value. I'm having trouble finding out what to do to save the public IP address. I thought that since I'm using fix_contact() I could save the contact header body, but $ct still contained the private IP address. Is this even possible? -- Andreas Sikkema

[OpenSER-Users] New H350 Module
by Christian Schlatter 14 Aug '07

14 Aug '07

Hello everybody! A new openser module named H350 is available in the openser devel repository. http://www.openser.org/docs/modules/devel/h350.html This module allows a script writer to implement H.350 based SIP digest authentication, call forwarding, SIP URI alias to AOR rewriting, and service level parsing. H.350 is an ITU-T Recommendation that standardizes how real-time communications (RTC) account data is stored in an LDAP directory. In particular, H.350.4 defines LDAP object classes for storing SIP account data. H.350 and H.350.4 are also described in IETF RFC 3944. The H350 module uses the LDAP module API to query H.350 directory servers, and it exports script functions to parse H.350 LDAP attributes into openser AVPs. This allows to integrate openser proxies with an enterprise/provider's existing identity management infrastructure. The module documentation should provide all information needed to use this module with your openser installation. Feel free to ask questions regarding this module on this list. /Christian - University of North Carolina

[OpenSER-Users] Click 2 Call / click To Call applications
by liran tal 14 Aug '07

14 Aug '07

Hey everyone, Following a very interesting but old and un-answered post here: http://www.voipuser.org/forum_topic_6616.html about the integration of Click-To-Call web applications with OpenSER I wanted to give it a try myself through the FIFO interface. Before jumping into scripts and code I was wondering if someone can make it clear how to use those fifo commands that "initiate" a call between 2 parties, from that post, the user uses: /* construct FIFO command */ $fifo_cmd=":t_uac:".$myfilename."\n". "REFER\n".$caller."\n". "p-version: ".$signature."\n". "Contact: ".$web_contact."\n". "Referred-By: ".$web_contact."\n". "Refer-To: ".$callee."\n". "\n". /* EoHeader */ ".\n\n"; /* EoFifoRequest */ Is there documentation available on the various fifo commands like this that I can use? Can I simply echo the fifo command string to /tmp/openser_fifo? Thanks in advance, Regards, Liran.

[OpenSER-Users] Logging failed registration attempt
by Edoardo Serra 14 Aug '07

14 Aug '07

Hi all, I'd like to log failed SIP REGISTER attempt either with xlog or with sip_trace() but I cannot understand where to put related code to catch the authentication error Here is the part of my opensr.cfg dedicated to REGISTER handling if (method=="REGISTER") { if (!proxy_authorize("exorsa", "openser_view")) { proxy_challenge("exorsa", "0"); exit; } if (!check_to()) { sl_send_reply("403", "Digest username and URI username do NOT match! Stay away!"); exit; } save("location"); exit; }; Tnx in advance Regards Edoardo

[OpenSER-Users] OpenSER coredumps on acc.so module
by liran tal 14 Aug '07

14 Aug '07

Hey everyone, I've enabled RADIUS accounting in my config file and setup radiusclient.confand the servers file with the appropriate data though OpenSER coredumps for some reason, this is the backtrace from gdb: #0 0xb7afc168 in test_config (rh=0x824d450, filename=0x824b240 "/var/csis/cfg/radiusclient.conf") at config.c:389 389 config.c: No such file or directory. in config.c (gdb) backtrace #0 0xb7afc168 in test_config (rh=0x824d450, filename=0x824b240 "/var/csis/cfg/radiusclient.conf") at config.c:389 #1 0xb7afbf49 in rc_read_config (filename=0x824b240 "/var/csis/cfg/radiusclient.conf") at config.c:312 #2 0xb7b1440b in extra2strar () from /usr/local/lib/openser/modules/acc.so #3 0x0808dab1 in init_child () #4 0x0806d15b in main () servers file: 192.168.0.1 test123 the servers file was before with a key of some non-standard chars like "test123!!5%^#" so I changed it to "test123" thinking that this might have caused it but this is not the reason. Thanks in advnace, Lir.

[OpenSER-Users] Werid records in 'presentity'table when PUBLISHing
by KevinKinnan 14 Aug '07

14 Aug '07

If the Route Header(sip:[ip add]:[port]) or Outbound Proxy(sip:[ip add]:[port]) in the PUBLISH request has no Lr parameter, the username field in 'presentity' table is null, and the domain field is also wrong. Without Lr parameter(no loose routing), the request received by Presence server is that placing the remote target URI into the Request URI(rfc 3561), and adding a Route Header with the value of the remote target URI. It seems the presence module just takes the Request-URI(which actually is the address of presence server) in the received request and save username and domain into the database. Thus, the username is null and the domain is the address of presence server. Is that right?? Why doesn't this happen in 1.2.0 version?THANK YOURegards,Kevin _________________________________________________________________ 通过 Windows Live Spaces 与朋友轻松共享您的生活。 http://spaces.live.com/spacesapi.aspx?wx_action=create&wx_url=/friends.aspx…

[OpenSER-Users] a=nortpproxy:yes in SDP and fix_nated_*
by liran tal 14 Aug '07

14 Aug '07

Hey everyone, When I'm doing sequential forking I'm seeing that for each gateway that doesn't answer and I move forward in the list of available gateways to forward the INVITE to, openser adds an "a=nortpproxy:yes" into the SDP so what happens is that the final gateway which is alive receives the sip header with multiple lines of "a=nortpproxy:yes" repeating themselves in the SDP and throws away the packet. >From my browsing in nathelper's code I see the only place that writes a "a=nortpproxy:yes" string to the SDP is the fix_nated_sdp function, and I'm actually not using it in my cfg but rather using fix_nated_register and fix_nated_contact which from what the README says are not handling the SDP part. And so I'm asking, where could it be coming from? And also, it would be easier if I can insert a piece of code that can do some regular expression miracles with the SIP header and remove any duplicate lines of the "nortpproxy" string. I'm running on openser 1.1.1 Thanks, Lir.

[OpenSER-Users] [avp_db_query] How to analize resulting AVP's row by row?
by Iñaki Baz Castillo 14 Aug '07

14 Aug '07

Hi, in order to implement a ACL system for incoming calls I've created a table "acl" with those columns: - priority - from_username - from_domain - to_username - group_from - group_to - type | action In that tables I store rules, and my idea is to work as a firewall: the first match is ejecuted (action=ALLOW or action=REJECT) and exit. But I can't do it since I don't know how to use all the AVP's JUST for the first row, then for the second: avp_db_query("SELECT priority,from_username,from_domain,to_username,group_from,group_to,type,action FROM acl", "$avp(s:priority);$avp(s:from_username);$avp(s:from_domain);$avp(s:to_username);$avp(s:group_from);$avp(s:group_to);$avp(s:type);$avp(s:action)"); This query results in many rows, but I can't analize each row, I just can compare each AVP with a value, but for that AVP they are possible all the values of any row. Because this I'm thinking in using the "exec" module to call a system script. Is not possible to access to tjhe query result by rows? Thanks for any help. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
