Hi Bogdan, Yes, it does. Please pay attention that the called number must be restored in branch_route[]. Also, I still don't know what to do if lookup() fails (the gateway is temporary down and therefore is not registered...) Any idea? Is it planned to add loops possibility to script language?

[Users] Please Help Me

by Ferianto monster

I am a college student in Polithecnic Caltex of Riau in Indonesia. I am in the third years now. In my last project, I want to build the VOIP with TLS system at my college because i think it is interesting. I have studied about it since one month , but i get many problems to undestand about the system. Here is some obstacles questions about the system that i have met: 1. How can the attacker eavesdrop the communication in VoIP (The way)? 2. How can TLS prevent the attacker to eavesdrop the communication? 3. How can TLS ensure the confidentially and integrity of communication? Why we don`t user other secure protocol? 4.Do all TLS` clients use Linux Operating System or they can use Windows? 5. How secure TLS to protect the communication? That is all the obstacles questions that i have met. I do hope any body can help me to answer those question. Please help me. Thank you very much.

RE: [Users] Routing to NATed gateways

by Leonid Fainshtein

In other words, the simplified configuration may be as the following: # Save original user name (the called phone number). avp_printf("$orig_called_num", "$rU"); if (load_gws()) { if (next_gw()) { if (lookup("location")) { avp_pushto("$ruri/username", "$orig_called_num"); t_on_failure("2"); route(x); # NAT and other usual staff there exit; } else { xlog("L_INFO", "I have to think what to do in this situation.\n"); sl_send_reply("404", "User Not Found"); } } } failure_route[2] { if (method=="INVITE" && t_check_status("408|500|503")) { if (!next_gw()) { t_reply("503", "Service not available, no more gateways"); } else { if (!lookup("location")) { xlog("L_INFO", "I have to think what to do in this situation.\n"); t_reply("503", "Service not available, no more gateways"); exit; }; t_on_failure("2"); t_on_branch("2"); t_relay(); } } } branch_route[2] { avp_pushto("$ruri/username", "$orig_called_num"); } Am I correct? Actually I don't know what to do if one of the gateways is off-line (lookup() failed).

Set in the LCR table some IP addresses which will be used as aliases: private addresses in 10.10.x.x class for example. Then register this IPs in usrloc pointing to the real GWs address. So you can do lcr (next_gw) and then lookup. for this to work, lcr must operate on RURI and not on DST_URI (not sure how exactly is working). regards, bogdan Leonid Fainshtein wrote: >Hi, >I'd like to use OpenSER for routing calls to NATed gateways.

[Serusers] Important please note: unable to load mysql.so and SER Version 9.3.0: MySQL 4.1.15.

by Dhiman D Chowdhury

Dear friends, If you are new to SER like I am, please note the followings: Setup: Red Hat Linux 9.0 or Red Hat Enterprise ES 3 and SER version 0.9.3. 1. When you try to load mysql.so module for your ser, you get an error. bad config. if you do ser -D -E . The result shows that mysql.so was unable to load due to libmysqlclient.so.12 was not found. Please note that the above mentioned Red Hat Linux includes a MySQL server version 3.23 which does not include the above file. If you do prefer to upgrade your mysql server please do not upgrade it to MySQL 5.0 rather upgrade it to 4.15. You are note done yet. Go to mysql.com and try to find out the following rpm file: MySQL-shared-compat-4.1.10a-0 RPM for i386 This file is from 4.1.10 which includes libmysqlclient.so.12 that is not present 4.1.15. Once downloaded install the file using the following command: rpm -i MySQL-shared-compat-4.1.10a-0.i386.rpm --force Hope this helps. Thanks Dhiman Deb Chowdhury http://dhiman.chowdhury.com

Re: [Serusers] FW: Call logs

Colin: Ahh, I've only done work with accounting on 0.9.x systems. This might explain why my instructions didn't help. I've copied the list on this reply in the hope that someone may know the answer since I will be out of the office all day today. I'll check back with you tomorrow. -Steve Colin Jordan wrote: >Hi Steve > >Thanks for this. The SER version is 8.1. Nothing appear in the database. > >Thanks for helping, > >Colin >
