[Users] Support for T.38
by Max Gregorian 23 Jan '07

23 Jan '07

Hi, Does anyone know if OpenSER supports T.38 for Fax over IP? Or has anyone managed to get it to work? I did some quick tests and what I got was the destination Fax machine rang, but the fax message did not arrive. I don't think the destination fax picked up. Setup was: Fax (PC modem) -> IP Gateway -> OpenSER -> PSTN -> Fax machine Is it possible the Fax tones are not being properly generated by OpenSER, and so not being recognised by the Fax machine? (For reference, the Gateway used is advertised as supporting T.38)

[Users] About the realm
by Howard Tang 22 Jan '07

Hi, I have (silly) question about the realm for authenication which I am not able to fix it. Currently, i have the following config. if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("1.1.1.1", "subscriber")) { www_challenge("1.1.1.1", "0"); exit; }; if (!check_to()) { sl_send_reply("401", "Unauthorized"); exit; }; consume_credentials(); save("location"); exit; }; if (method=="INVITE") { if (!proxy_authorize("1.1.1.1","subscriber")) { proxy_challenge("1.1.1.1","0"); exit; } if (!check_from()&& !does_uri_exist()) { sl_send_reply("403", "Use From=ID"); exit; } consume_credentials(); }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; My problem is user can only register or make phone call using 1.1.1.1 as a domain. I have setup a domain name on this ip address. for example sip.proxy.com. when i set up sip.proxy.com as the domain/proxy address in the UA, i was not able to register and received a 503 service unavailable. What do i need to do to allow user register using ip address or the host/domain name at the same time? currently i have it working for ip address only. In the subscriber tables-domain column, i have ip address for the users, do i need to add another entry with the domain name in the domain column instead of he ip address? if that is the case, i will have 2 username which the same number in the table. Please help. -- Howard Tang

[Users] OpenSER v1.1.1 released
by Daniel-Constantin Mierla 22 Jan '07

22 Jan '07

Hello, version 1.1.1 of OpenSER has been released. It is an update of version 1.1.0 and includes the fixes for the issues discovered in version 1.1.0, therefore all people using 1.1.0 should upgrade to this new version. For people using sms, permissions, postgres, unixodbc, osp, it is highly recommended to move to this release, in the case no CVS updates were done after v1.1.0 (if you installed and maintain OpenSER from CVS, then you have to use branch rel_1_1_0, as it was for v1.1.0). The compatibility of the configuration file and database has been preserved (you do not need to do database reinstallation). Some details about v1.1.1 can be found at: http://www.openser.org/index.php?option=com_content&task=view&id=47&Itemid=… Detailed changelog: http://www.openser.org/pub/openser/1.1.1/ChangeLog Sources can be downloaded from: http://openser.org/pub/openser/1.1.1/ The documentation for modules is posted at: http://openser.org/docs/modules/1.1.x/ If someone wants to contribute with packages for different distros, please send the link from where can be downloaded to team(a)openser.org. Cheers, Daniel

[Users] Comapring keywords in openser...
by Premnath, KN 22 Jan '07

22 Jan '07

Hi, How to compare core keywords in openser? I wanted to compare to_uri and uri is same.. Eg: if(uri == to_uri)... But there is a syntax error thrown, stating "only myself or string" can be compared... Then could I use if(uri=="$to_uri") Thank You. With warm regards, Premnath, KN The new company Nokia Siemens Networks is expected to start operations in the first quarter of 2007, subject to customary regulatory approvals, the completion of standard closing conditions, and the agreement of a number of detailed implementation steps.

[Users] Asterisk Integration
by Víg Pál 22 Jan '07

22 Jan '07

Hi List members, I am planning to bulid a system for large scale deployment. Looking at Openser features and Asterisk capabilities I decided to build a system on these platforms, but faced the problem of integration. What is the best method of integration ? I read some columns in the docs, and can not decide... I came from the network world and can understand protocols and IP communication quite well. I think I should do the following : CLIENT <---> Internet <---> Openser machines (load balanced) <---> Asterisk machines (behind NAT, also load balanced, doing mainly codec conversion and switching logic) My guesses are : - use dispatcher on the frontend(s) - do not use dispatcher, but rewrite the packets by some programmatical way - any other solution ? I'd like to spare some energy on this not to start developing some not working solution ;) Thanks in advance, Pal Vig

Hi. Is it possible to use a avp variable in functions' second parameter when I'm using regular expression? For instance: avp_check("$ruri","re/sip:$avp(s:prefix).*$") I didn't see any code doing that. Thanks in advance.

[Serusers] MySQL Accounting
by Rosa De Santis 20 Jan '07

20 Jan '07

Hello all. I have accounting with MySQL working fine. I have records on my acc table. Please, I'd like to know if there is a tool to process the acc table entries to get completed calls on another MySQL table, taking into account missing BYEs or CANCELs. I found that CDRtool can do this and more, but its not free and it seems to be complicated. Thanks in advance for any help Rosa. _________________________________________________________________ Descubre Live.com - tu mundo en línea reunido: noticias, deportes, el tiempo, y mucho más. http://www.live.com/getstarted
