Re: [Freeswitch-dev] switch_odbc.c connect "max_tries" variable
by Vitalii Colosov 20 May '10

20 May '10

Hi, I am using core ODBC for MySQL connect. Trying to implement failover using 2 servers - main and backup. If main server is not responding, it should try to query backup server. The following is used in my module: if (switch_odbc_handle_callback_exec(*globals.master_odbc*, sql, my_func_callback, &pdata, NULL) != SWITCH_ODBC_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "(***)Error running query on master database: [%s]\n", sql); switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_INFO, "(***)Trying backup database: [%s]\n", globals.backup_odbc); if (switch_odbc_handle_callback_exec(*globals.backup_odbc*, sql, my_func_callback, &pdata, NULL) != SWITCH_ODBC_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_CRIT, "(***)Error running query on master and backup database: [%s]\n", sql); } } ... Right now it tries to reconnect to main server 120 times before it gives up and goes to backup server. I found the following in the switch_odbc.c: int max_tries = 120; Is there is a way to disable this check, so if it will not be able to connect to master, it will immediate go to backup server? I know I can change the source, but this will be already "customized core" - don't want to go in this direction. Or maybe there is a better way to handle database fail over in my module? Thank you, Vitalie

[Freeswitch-dev] sending custom SDP in 200 OK
by Raj Kiran Talusani 10 May '10

10 May '10

I have written a application called mod_custom. In this module i would like to set a user-defined RTP port and IP adress and then send the 200 OK (answer the call). But i see that, before my application is invoked, 183 message is sent with SDP. And i didnot find a way to either disable sending 183 and just send 180 OR modify the SDP to be sent in 200 OK. please help. Rajk

[Freeswitch-dev] Build fails on Suse
by Matt White 10 May '10

10 May '10

I'm using the opensuse build service to create rpm's for Suse. The build fails with the following error below. I think its due to the gcc 4.3 used on SLE11 as I can't replicate it in older versions I: Expression compares a char* pointer with a string literal. Usually a strcmp() was intended by the programmer E: freeswitch stringcompare strings/apr_snprintf.c:1261 Any thoughts? I'm using the nightly snapshot. -M

[Freeswitch-dev] Create applications in FreeSWITCH
by Vitalii Colosov 23 Apr '10

23 Apr '10

Hi dear group, I would like to start writing plugins (applications) for FreeSWITCH that will be called from dialplan: <action application="my_cool_application"...> Could you please provide me some steps following which I will be able to create "helloworld" C/C++ application that will be called from dialplan? Or some link if this is already described somewhere... I tried to google but did not find that. Then, if I will create something useful, I will contribute it to the community with pleasure... :-) Thank you very much! Vitalie

I have a freeswitch server running at one location. I want to setup a sip phone at another location (outside the local freeswitch network). can someone recommend a sip phone or adapter that is not too expensive and will easily connect/work with the freeswitch server at location one?

[Freeswitch-dev] Fwd: thousands of memory leaks when using own module and mfc dll
by Sebastian Rudek 22 Apr '10

22 Apr '10

Dear Freeswitch developers, i have a problem with FreeSwitch (Version 1.0.4) and my own module, which loads a MFC based DLL -- where obviously memory leaks are produced. let me try to explain what i have. 1) First of all, let's discuss the case where everything works fine in freeswitch. My FreeSwitch module (which here loads no further DLL) is loaded and unloaded correctly when a call is accepted and later on hung up. 2) Then i load an "empty" DLL, without MFC and all that stuff, which i created, within my FreeSwitch module. I do this when accepting a call. when hanging up, I FreeLibrary(), quit FreeSwitch and everything is fine. No memory leaks, no errors, just everything as it ought to be. 3) But then! Then i take my module and load a DLL which uses MFC. and then, when after unloading the DLL on hanging up, I exit the FreeSwitch application and get that many memory leak reports in the debug out of visual studio 2008... that leads me to my question: Are there any know issues with FreeSwitch and MFC DLLs ? I tried to simulate the problem with creating an Application which simply loads the Non-MFC DLL (see number 2 above). No memory leaks. Also, no memory leaks are detected when loading the MFC-DLL from 3) (see above). but Visual Studio detects one (!) 4-byte-memory-leak when loading the MFC DLL inside the Non-MFC-Dll (like the FreeSwitch module ought to do it). Back to the question, if there is an issue with FreeSwitch and MFC-DLLs. The object dump, which Visual Studio gives to me, says that leaks are detected at "VARCHAR(255)", "shma", "TeleTone" or "loopback.auto". I do not know where that comes from. Maybe, you have an idea which you could share with me to solve the problem, on which i have spent really much time already... I just attach the out as text file. Thank you so much in advance Sebastian

[Freeswitch-dev] windows json build
by Tamas Cseke 22 Apr '10

22 Apr '10

Hello, I've seen the json upgrade (0.8 ->0.9) has been done for windows as well in r17064. If it would work, I'd like to fix the windows build for mod_json_cdr (http://jira.freeswitch.org/browse/MODEVENT-62) I was trying with vc++ 2008 express, but I can't compile jsonlib. json_util.c(62) : error C2065: 'O_RDONLY' : undeclared identifier json_util.c(97) : error C2065: 'O_WRONLY' : undeclared identifier json_util.c(97) : error C2065: 'O_TRUNC' : undeclared identifier json_util.c(97) : error C2065: 'O_CREAT' : undeclared identifier Is it works for you? does mod_curl build works on windows? or the jsonlib doesn't support windows at all (it seems to me) ? Thanks in advance, Tamas
