[Serusers] Creating CDRs from SERs accouning records

by Frank Fischer

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

[Serusers] assertion failed in t_retransmit_reply; race condition in t_newtran?

by Valentin Nechayev

Hi, we had got series of SER cores with failed assertion in t_retransmit_reply(): assert(t->uas.response.dst.send_sock); Essential backtrace part: #0 0x48167fc4 in kill () from /usr/lib/libc.so.4 #1 0x481a993e in abort () from /usr/lib/libc.so.4 #2 0x481858d3 in __assert () from /usr/lib/libc.so.4 #3 0x48281da3 in t_retransmit_reply () from /usr/local/lib/ser/modules/tm.so #4 0x48277433 in t_newtran () from /usr/local/lib/ser/modules/tm.so This place from ser.cfg: if (!t_newtran()) { sl_send_reply("500", "could not create transaction"); break; }; response.dst.send_sock is filled in init_rb(), which is called from t_newtran(). t_newtran() has the following: === cut === UNLOCK_HASH(p_msg->hash_index); /* now, when the transaction state exists, check if there is a meaningful Via and calculate it; better do it now than later: state is established so that subsequent retransmissions will be absorbed and will not possibly block during Via DNS resolution; doing it later would only burn more CPU as if there is an error, we cannot relay later whatever comes out of the the transaction */ if (!init_rb( &T->uas.response, p_msg)) { LOG(L_ERR, "ERROR: t_newtran: unresolvable via1\n"); put_on_wait( T ); t_unref(p_msg); return E_BAD_VIA; } return 1; === end cut === Does there race condition between UNLOCK_HASH(), init_rb() and parallel t_newtran() from another SER process exist? Details: FreeBSD 4.10, SER 0.9.3 (with PortaOne additions, but not essential for the question). -- Valentin Nechayev PortaOne Inc., Software Engineer mailto:netch@portaone.com

[Users] Serial forking

by Bogdan-Andrei Iancu

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

RE: [Users] Sending Authorisation Credentials

by Douglas Garstang

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.

[Serusers] Adding a user

by Xavier TRENTIN

Hi all, I use ser with dbtext. I have two questions. 1) I 've added many fields in my subscriber table, and I'd like to know if all the table is loaded in memory when ser starts or if it only loads the fields it needs? 2)When I add users in my subscriber table, I must restart ser to load the new accounts. I thought there were a specific serctl which worked with dbtext, but I can't find it. Can any one give me a link where I can dowload it, and does it allow to insert new users in the text table and in the in loaded table at the same time? If not, how can I add my new users directly in memory? Thanks in advance. B.R. Xavier.

FW: [Serusers] Repeated Register Message

by Pravesh

Hi Chan, I also faced a similar problem in which when UA sends REGISTER to SER from different IP address than what is present in the contact header of the REGISTER message, then SER actually stores two AORs for the UA, i.e. one AOR is the actual contact header value & other is the same username with the IP address & port from which I sent the REGISTER message. I am not sure for the reason of this kind of behavior. Anyone from the SER developer list should be able to answer this query. So also forwarding this message to developers list also. Regards, Pravesh -----Original Message----- From: serusers-bounces(a)iptel.org [mailto:serusers-bounces@lists.iptel.org] On Behalf Of tcchan Sent: Wednesday, November 30, 2005 8:57 AM To: serusers(a)lists.iptel.org Subject: [Serusers] Repeated Register Message Hi All, I encountered a situation that somehow a UA keep on Registering with the server with the same IP but on different port. So SER, thought that there are multiple instances of the same username and save the various location into the database. The problem is it registers so often that the memory is full not very long. I suspect it has something to do firewall but I am not sure. Has anyone encounter this problem before? Any hint?? For the time being, is there a way to limit the number of REGISTER message that the SER will take?
