[Serusers] Creating CDRs from SERs accouning records
by Frank Fischer 01 Dec '05

01 Dec '05

Hi all i'm looking for a free/opensource application that generates CDRs (not XDRs, must not be rated) from the accounting data/events generated by SER (i think this is usually called normalization). I think this would have to be an application that is able to match INVITEs and BYEs and form CDRs with call start timestamp, call duration and so on. I had a look at the list of accounting software on the iptel.org website, but most of there applications are highly integrated accounting/billing solutions, far more than what i need (and also most of them seem to be commercial products). In the mailinglist archive i only found some references to CDRTool which seems also to be commercial. Obv. there must be a free version of CDRTool but neither i'm sure whether it implements exactly what i need so i could "grab it" for my own purposes nor could i find a place to download the free version). Does anyone know if there is such a kind of application available? Or any other idea how to deal with my requirements? Thanks a lot for your help Frank

[Users] Serial forking
by Bogdan-Andrei Iancu 01 Dec '05

01 Dec '05

Hi, I just committed serial proper forking support into core - it was migrated from LCR module. I mean proper, since it has q value support and it can be used by any module without any inter-module dependencies. The idea behind was to allow to all module that performs parallel forking to do also serial forking - exec, enum, registrar, etc. There are two new script functions : *serialize_branches(n)* : it inherits the functionality of load_contacts() from LCR; gets all parallel branches and convert them into AVPs for serial forking; numerical parameter 'n' says if any previous AVP should be removed (if non-0) or not (if 0). Returns true is no error (even if no serialization happened). *next_branches()* : it inherits the functionality of next_contacts() from LCR; get (based on q value) the next contact(s) to be used in sequential forking. Returns true only if a new contact was got to be used. The AVP containing the branches is accessible only via alias - its ID is not configurable or visible; the alias (automatically exported by core) is "serial_branch" - it is visible from any module that uses the avp core aliasing system. here are some examples of how to uses this new functionality: 1) enum doing serial forking: { ..... enum_query("e164.arpa.","voice"); serialize_branches(1); if (!next_branches()) { sl_send_reply(...no enum found...); exit; } t_on_failure("1"); t_relay(); } failure_route[1] { if (next_branches()) { t_relay(); } } 2) same for registrar, just replace enum_query() with lookup("location"). NOTE that this will not work yet if there are nated contacts: there is no support to save also the flags and the dst_uri in order to perform proper nat traversal. The code was not yet heavily tested, so any help on this is highly appreciated. On the TO-DO list, related to this subject are: 1) SRV lookup to use this functionality to provide any additional entries. 2) full support for registrar for nat traversal 3) remove load/next_contacts() from LCR (once this new functions prove to be stable). regards, bogdan

I don't think this will work. That means not only would the Asterisk box need to let REGISTER requests through without authentication, it would also need to let every other type of request through (INVITES come from OpenSER as well). You can't drill down to that level of detail in Asterisk and tell it to not authenticate for REGISTERs from OpenSER, but to authenticate for INVITE requests.

Re: [Serusers] can't connect to RTP proxy

hi, i read the onsip.org <http://onsip.org> getting started manual. i tried again with ser and rtpproxy but i received same errors... then i decided to try with mediaproxy: i downloaded ser-0.9.0 (emerged from gentoo portage) and mediaproxy-1.4.2. i followed this instructions: http://www.voip-info.org/wiki-MediaProxy but i cannot even start it (neither --help works) $ /etc/init.d/mediaproxy start : bad interpreter: No such file or directory and: $ /usr/local/mediaproxy/mediaproxy.py : No such file or directory i got ensured that EOL are not dos-style and i tried that a simple file called test.py (it just prints something) just to make sure that python works... sorry, i understand it is not properly a ser problem but i don't know where else to ask... thank you so much!

Re: [Serusers] domain trouble

Nevermind, I was putting the username only in the authorization user and it needs the username and the domain ie. bob(a)foobar.com.

Okay, that makes a lot of sense. But... I did it and changed the realm accordingly in my UA and now it won't authenticate with either realm. What now? >>> Klaus Darilion <klaus.mailinglists(a)pernau.at> 11/29/2005 1:56 AM >>> The SIP_DOMAIN is only used for serctl as default domain (when you create a new user without specifiying the domain of the SIP AoR).

[Users] t_replicate after failure
by Douglas Garstang 30 Nov '05

30 Nov '05

In the scenario below, if the first t_replicate fails because 192.168.10.5 returns "Not Found", the second t_replicate command does not execute. Why? How can I make it execute? Call me crazy, but this doesn't seem at all intuitive to me. In a functional programming world, if the first fails, the next should still run. if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("voip.com", "subscriber")) { www_challenge("voip.com", "0"); exit; }; save("location"); t_replicate("192.168.10.5","5060"); t_replicate("192.168.10.7","5060"); exit; }; Thanks, Doug.

[Serusers] Acc fields
by Richard C. Thompson 30 Nov '05

30 Nov '05

I hope someone can help answer this question. I am using Mysql acc table to generate cdr's and I am having problems with missing BYE records. I am using the totag field as a unique identifier to match up the INVITES, ACK and BYE's. Is this the field I should be using? I know ser changes the BYE uri to reflect the uac that issued the BYE but I don't know if it changes the totag. Thanks for your reply. Rick Thompson

[Users] Sending Authorisation Credentials
by Douglas Garstang 30 Nov '05

I have user agents registering with OpenSER. I wanted to 'copy' the registration to an Asterisk server, so I modified a standard openser.cfg as such: if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("voip.com", "subscriber")) { www_challenge("voip.com", "0"); exit; }; save("location"); t_replicate("192.168.10.7","5060"); # Added this line... exit; }; I just stuck the t_replicate() call in there. OpenSER sends the REGISTER packet to the Asterisk box who requests credentials. How can I get OpenSER to send credentials (ie act as a UAC) for a given user, to a UAS? Thanks, Doug

[Serusers] CDRTool
by Martin Anderberg 30 Nov '05

30 Nov '05

(I know this is a bit out of topic, please dont feel offended) Hi there! I was about to try out CDRTool to see if it does what it says - however, it doesn't run at all. There is no forum (that i know of) that discusses CDRTool so i hope someone here can help. The box is a debian unstable (tried stable aswell) and CDRTools is installed according to the instructions. When i try to execute ie something in the scripts/-directory i get the following error: Warning: main(SOAP/Client.php): failed to open stream: No such file or directory in /var/www/CDRTool/rating_lib.phtml on line 5 Fatal error: main(): Failed opening required 'SOAP/Client.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/CDRTool/rating_lib.phtml on line 5 Ok, SOAP/Client.php doesn't exist, SOAP/client.php does however. A symlink ought to solve that problem? Running in the scripts/-directory again gives the error: #!/usr/bin/php4 Fatal error: Cannot redeclare class db_sql in /var/www/CDRTool/phplib/db_mysql.inc on line 13 Now i'm stuck and dont know what to do. If someone has any clues, please let me know. Thanks Martin
