[Users] inner join using OpenSer database API

by Tiberius DULUMAN

Hello, I need to write an OpenSER module that should persist it's data in a database and sometimes access it from there. After reading the Database API of OpenSer documentation, I've start the implementation, but soon I've got one major problem: I can't see any way to select data by joining more tables. Is it possible to do this? dbf.query callback seems to work only with the current table from db_con_t structure.

[Users] gateway redirect

by Joao Pereira

Hello I'm using a Patton gateway with my Openser and everything works fine, except when OpenSER has to redirect a call to Asterisk. If I use X-Lite, OpenSER can redirect the call to Asterisk, but with the Patton gateway it doesnt work. In the moment Im just using rewritehost("....."); The problem could be in the Patton gateway configuration, but I just want to be sure... does OpenSER needs some special configuration in order to the redirects to work? Thanks Joao Pereira -- ______________________________________________ João Gomes Pereira FCCN Av. do Brasil, nº 101 1700-066 Lisboa tel: +351 218 440 100 - fax: +351 218 472 167 email|SIP: joao.pereira(a)fccn.pt http://www.fccn.pt ______________________________________________ ---

[Users] Re: Memory issues

by Papadopoulos Georgios

Hello, We have exactly the same problem. Openser after a few hours starts loging "out of memory" errors and soon after that it cannot process any messages. I am using 1.2 branch from SVN and the last export that I got was at the begining of June, the revision number was 2333. Today I was able to catch the problem while it is happening and I did a memory dump on the process that run out of memory (process 4197). ps shows that this process is a receiver with id=1 and child=0. I have not restarted the server yet, but pretty soon I will have to restart because more processes will run out of memory. If there is some additional information (statistics, ngrep etc) that I could gather while the server is still running, please let me know. I don't have quick access to a public ftp site, so if someone can take a look at the log file and the memory dump, please let me know and I will email it (1MB). thank you for any help.

[Users] Memory issues

by Christian

Hi All, I have a recurrent memory problem with openser 1.2.0. In this case it only acts as a SIP router. No registration, accounting etc. and only approx. 20 simultaneous calls. Here is the problem: everything works fine (calls from/to PSTN through different SIP servers), but after a few days, "out of memory" errors start to occur. After this, calls don't work anymore, even if openser continues to run. Here is a part of the log, showing the first errors: Jun 5 17:25:43 localhost SER[27772]: ERROR: build_res_buf_from_sip_res: out of mem Jun 5 17:25:43 localhost SER[27772]: ERROR:tm:relay_reply: no mem for outbound reply buffer Jun 5 17:25:43 localhost SER[27772]: ERROR: via_builder: out of memory Jun 5 17:25:43 localhost SER[27772]: ERROR: build_local: no via header got from builder Jun 5 17:25:43 localhost SER[27772]: ERROR: attempt to build a CANCEL failed Jun 5 17:25:50 localhost SER[27772]: ERROR: build_res_buf_from_sip_res: out of mem Jun 5 17:25:50 localhost SER[27772]: ERROR:tm:relay_reply: no mem for outbound reply buffer Jun 5 17:25:50 localhost SER[27772]: ERROR: build_res_buf_from_sip_req: out of memory ; needs 410 Jun 5 17:26:11 localhost SER[27772]: ERROR: build_res_buf_from_sip_res: out of mem Jun 5 17:26:11 localhost SER[27772]: ERROR:tm:relay_reply: no mem for outbound reply buffer Jun 5 17:26:11 localhost SER[27772]: ERROR: build_res_buf_from_sip_req: out of memory ; needs 404 Jun 5 17:26:25 localhost SER[27772]: eval_elem: no more memory Jun 5 17:26:25 localhost SER[27772]: do_assign: no value in right expression Jun 5 17:26:25 localhost SER[27772]: ERROR: build_res_buf_from_sip_res: out of mem Jun 5 17:26:25 localhost SER[27772]: ERROR:tm:relay_reply: no mem for outbound reply buffer Jun 5 17:26:25 localhost SER[27772]: ERROR: build_res_buf_from_sip_req: out of memory ; needs 420 Jun 5 17:26:25 localhost SER[27771]: ERROR:forward_reply: no 2nd via found in reply Jun 5 17:26:31 localhost SER[27772]: ERROR: build_res_buf_from_sip_res: out of mem Jun 5 17:26:31 localhost SER[27772]: ERROR:forward_reply: building rpl from req failed Jun 5 17:26:33 localhost SER[27772]: ERROR: build_res_buf_from_sip_res: out of mem Jun 5 17:26:33 localhost SER[27772]: ERROR:forward_reply: building rpl from req failed Jun 5 17:26:38 localhost SER[27772]: ERROR: insert_new_lump_after: out of memory Jun 5 17:26:38 localhost SER[27772]: ERROR: insert_new_lump_before: out of memory Jun 5 17:26:38 localhost SER[27772]: insert_RR(): Error while inserting conditional lump Jun 5 17:26:38 localhost SER[27772]: ERROR: subst_str: mem. allocation error (res->s) Jun 5 17:26:38 localhost SER[27772]: ERROR: do_action: memory allocation failure Jun 5 17:26:38 localhost SER[27772]: ERROR: build_res_buf_from_sip_req: out of memory ; needs 375 Jun 5 17:26:38 localhost SER[27772]: ERROR: mk_proxy: memory allocation failure Jun 5 17:26:38 localhost SER[27772]: ERROR:tm:t_forward_nonack: failure to add branches At this point, similar errors continue to appear and the only way to recover is to restart openser.

[Users] Interaction Presence Agent - Presence User Agent

by Schumann Sebastian

Dear all, I have a question for understanding: I have implemented one OpenSER as Registrar and one OpenSER as Presence Agent plus XCAP Server 1.0.0. This is all working so far with newest SVN Release (Big Thanks to Ovidiu and Anca for the hint) of OpenSER. Now I want to deploy a Web-Front-End for user interaction with the Presence Core, because not all clients used are SIMPLE capable. User of non-capable devices should be able to just login and change their presence state. They do not necessarily have to be registered at the registrar, why PUA+ pua_usrloc on registrar side is no choice. I was thinking about another OpenSER deployed as PUA plus the pua_mi module for a solution. It gets commands from Web-Frontend via PHP, forwarded to the FIFO with pua_mi module. The problem I have now is that the messages are sent just once. Means a user changes his presence state, PUA sends a PUBLISH to PA but after the expiry the user appears to be offline. Is there any possiblitiy to let the PUA send messages constantly, when the user selects online - means all the time until offline is selected? I was thinking about many possiblities (cronjob or shellscript running all the time during online time and sending data to FIFO) but they are more or less just work-arounds.
