[OpenSER-Users] OpenSER as Asterisk/CallWeaver frontend
by Eugene Prokopiev 28 Aug '07

28 Aug '07

Hi, Can anybody tell some success story about using OpenSER as Asterisk/CallWeaver frontend? I tried to googling first but where are no detailed useful stories :( Now I have CallWeaver (Asterisk fork) installed on Linux server which connected to 2 different providers via one wan interface but 2 ip addresses from one network, for example: eth0 - 10.0.0.2/24 -> provider1(10.0.2.1) - 10.0.0.3/24 -> provider1(10.0.3.1) So, I need send SIP requests to provider1 from address 10.0.0.2/24 and to provider2 from 10.0.0.3/24. This must be done because my internet provider must account trafic on router 10.0.0.1 for 2 VoIP providers separately and it's billing system can do it only by different source ip addresses and can't do it by destination ip addresses. I can separate SIP requests between 2 ip addresses with linux kernel 2.6.18 or higher by using ip_nat_sip iptables module and MARK/SNAT. But this approach can't be used in OpenVZ virtial environment in which CallWeaver must be used. Is it possible to send SIP requests from CallWeaver via OpenSER and modify them with OpenSER to replace source addresses in UDP headers and SIP headers? How can I say CallWeaver to send SIP requests via OpenSER? How can I implement this routing logic in OpenSER? Can anybody give me a simple example? -- Thanks, Eugene Prokopiev

[OpenSER-Users] Unauthorized Calls - [Openser - X-lite]
by Jeferson Prevedello 27 Aug '07

27 Aug '07

Hello, I implemented an environment using to openser + mysql. The enviroment functions perfectly, however I perceived that users (branches) not registered in mysql are generating called. I installed the X-lite softphone in my computer trying to reproduce the situation. In the properties of configuration of the X-lite, "field Password" I type "trash" as password (wrong password). The display of X-lite showed the following message: "Registration error: 401 - Unauthorized". In the contacts drawer I add a contact (double click on the new contact), and the call was generate without restriction (very bad). Some idea of as I solve this problem? Thanks Regards Jeferson

Fw: [OpenSER-Users] Unauthorized Calls - [Openser - X-lite]
by Simone Torri 27 Aug '07

Hi Guys, Here in my company I have the same problem. The solution that I adopted was apply the proxy_authorize function and restrict all incoming calls. I use openser only for originate calls. Some tip ? Cheers, Torri ----- Original Message ----- From: "Jeferson Prevedello" <jprevedello(a)terra.com.br> To: "Dan-Cristian Bogos" <dan.bogos(a)gmail.com> Cc: <users(a)openser.org> Sent: Monday, August 27, 2007 12:26 PM Subject: Re: [OpenSER-Users] Unauthorized Calls - [Openser - X-lite] Hello DanB, More a problem ! :-( I apply the following configuration in my openser.cfg: if (method=="INVITE") { if (!proxy_authorize("", "subscriber")) { proxy_challenge("","0"); exit; } }; I perceived that with the configuration above 'only' registered users can generate called, however I not receive more called originated through of PSTN or of any branch of PBX. I believe these calls are deny because the source (PSTN - Branches) not are registering in the openser server. Is possible to apply the configuration above only for calls 'originated' from openser ?

I would suggest taking a more standard configuration (u can find many examples on this location: http://openser.svn.sourceforge.net/viewvc/openser/branches/1.2/examples/) and use 1.2 branch of software for start, and experiment with it into some lab environment. It is a bit difficult as a beginner to start directly experimenting on a production configuration, perhaps written by somebody else without understanding it. You will end up having big issues when troubleshooting in production environment. The tip I gave you would be really easy to implement it with a block of few lines, eg: if (is_method("INVITE")){ if (!proxy_authorize("", "subscriber)) { proxy_challenge("","0"); exit; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); exit; }; }; Documentation for you to understand those lines here: http://www.openser.org/docs/modules/1.2.x/auth_db.html#AEN192 Usually, there is a loot of documentation and howtos in openser wiki, so I would suggest you having a glance on some titles which look close to your needs as a beginner. http://www.openser.org/dokuwiki/doku.php Cheers, DanB On 8/27/07, Jeferson Prevedello <jprevedello(a)terra.com.br> wrote: > Hello DanB, > > Thanks! > > As DanB´s suggestion, I tried to implement a mechanism that only allowed > authenticated members make calls, but my configuration didn´t function. > > This is my first project with openser, therefore I do not have much > experience.

[Users] understanding SEMS
by Victor Gamov 27 Aug '07

27 Aug '07

hi guys! can somebody explain me how SEMS works with SER/OpenSER. As I conceive proxy sends requests to SEMS via unix socket. Then SEMS needs constructs reply or new request and ask proxy to send it. But where reply come to proxy? into onreply_route[0] block? is it possible to use t_on_reply() function when initial request writing to SEMS to ask proxy to use specific onreply_route[] block? Thanks for advise! -- CU, Victor Gamov

[OpenSER-Users] Upload to XCAP Server - 405 Method Not Allowed error.
by Kriti Wadhwa 27 Aug '07

27 Aug '07

Hi, I am testing Presence service using Openser, XCAP server... After firing up the UCT IMS Client in the final step, everything goes well except the "Upload to XCAP Server" part... On clicking that I get: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>405 Method Not Allowed</title> </head><body> <h1>Method Not Allowed</h1> <p>The requested method PUT is not allowed for the URL /xcap-root/pres-rules/user/alice/presence_rules.xml.</p> <hr> <address>Apache/2.0.54 (Fedora) Server at xcap Port 80</address> </body></html> Tried changing permissions to the presence_rules.xml file and also made all necessary changes in httpd.conf file but in vain... Hope someone can help me in this.

[Serusers] acc_db_request milliseconds
by Sho Aihara 27 Aug '07

27 Aug '07

Hello. Please teach me about acc_db_request for the call charge. For example, when call starts (ACK), my ser.cfg acc_db_request will executed to insert a new row for db. timestamp ------------------- 2007-08-24 23:50:00 And when call ends (BYE), acc_db_request executed. timestamp ------------------- 2007-08-24 23:50:03 These values were considered about milliseconds? For example... timestamp ------------------- 2007-08-24 23:50:00(.000) timestamp ------------------- 2007-08-24 23:50:03(.525) In this case, I think that the interval of these time becomes 4 seconds If I use these values for the call charge (round-up millisecond). Or, has the time recorded with BYE already been rounded up? Thanks, Sahria

This was one of the reasons he left CDC to form Cray Research (which, mind you, CDC was very much in support of, as they had much faith in Cray's abilities). He argued vehemently that the peripherals were unnecessary products, and eventually, this disagreement caused him to leave and form Cray Research, where he could be free from 'management failures' as he liked to call them. The CDC, however, was extremely supportive of Cray Research, and put money and development time into it, much to Cray's chagrin. Then, again, when Cray Research was faced with the decision of whether to build computers that people would buy or computers for the sake of building computers, they understood that they needed to stay in business, and decided on the path that would lead them to solvency. This caused Cray to leave his own company and form Cray Computers. He vowed that CCC would make fast and powerful computers and that nothing else would be a priority. He assumed that speed and power were the ultimate goal and that everything would fall into place if he achieved that goal. Of course, his shortsightedness caused bankruptcy. Incidentally, having had to use NOS on a regular basis back in the day, I would scarcely call it an operating system. Anything that lets you manually change the bits in memory of a running program isn't an OS, it's just a GUI for the hardware. ;) N.
