== ISSUE building FreeSwitch on Windows
by marco blaisou 23 Oct '11

23 Oct '11

Hi guys, For the few days I've been unsuccesfull in building FreeSwith on Windows 7 I did follow the Wiki line per line, but some thing is really going wrong: > apparently the files in /libs directory are not loaded from the net (ie the util.vbs does seem to load and unpack the libs) error is : *freeswitch\libs\win32\util.vbs(184, 2) msxml3.dll: Le système ne trouve pas la ressource spécifiée (ie system doesn't find specified resource)* > then obviously the compiler starts complaining about missing stuff such as: *c:\users\jc\desktop\voip\freeswitch\freeswitch\src\mod\endpoints\mod_sofia\mod_sofia.h(47) : fatal error C1083: Cannot open include file: 'switch_version.h': No such file or directory* To summarize: I loaded the FreeSwitch git repository with TortoiseGit My config is : Windows 7/64bits VSC2008 sp1 Windows SDK 7.1 My firewall is desactivated as suggested I did follow the recommendation to clear some files: *del libs\apr\include\apr.h del libs\js\config.h del libs\js\src\jsautocfg.h del libs\js\nsprpub\pr\include\prcpucfg.h del libs\iksemel\include\config.h del libs\xmlrpc-c\xmlrpc_config.h del libs\libsndfile\src\sfconfig.h del libs\sofia-sip\libsofia-sip-ua\su\sofia-sip\su_configure.h del libs\js\nsprpub\pr\include\prcpucfg.h cd libs\win32\libsndfile rename config.h sfconfig.h* Could a guru provide some hints on how to solve this??? Thanks

Call-ID formatting
by Kurtis Heimerl 22 Oct '11

22 Oct '11

According to the sip standard, call-ids should have a "host" trailer (e.g., f81d4fae-7dec-11d0-a765-00a0c91e6bf6(a)foo.bar.com) Reference: http://www.ietf.org/rfc/rfc2543.txt Section 6.12 FreeSwitch doesn't do this, omitting the "@foo.bar.com" portion of the above. Is there any reason why this is the case? This seems too large of an issue to be a bug or oversight. Here's an example from a FS MESSAGE: Call-ID: 000b3694-76e4-122f-55b3-5cff350d9de5

Calling Python Application from Chatplan (mod_sms help)
by Kurtis Heimerl 21 Oct '11

21 Oct '11

I'm pushing this to FreeSwitch-dev as mod_sms is still under active development. Any way to call a Python Application from the chatplan? This works: <action application="set" data="test=${python(OpenBTS_Parse_SMS)}"/> But I can't monkey with the session variables with the fs_api call. Instead, I want to do this: <action application="python" data="OpenBTS_Parse_SMS"/> and this fails in the following way: 2011-10-18 16:12:02.776298 [ERR] switch_loadable_module.c:705 Invalid chat application interface [python]! The mod_sms page seems to indicate that lua works just fine from the chatplan... is this just not implemented yet? Can I do that? Thanks!

Re: [Freeswitch-dev] get variable value

Yes I am using ESL but don't get_header functions need to catch an event first. I was thinking if there was already a builtin function. I can't remember exacty because it was a while ago but I used something like this in ruby @con.api("uuid_getvar", "#{@uuid} myvar").getBody > ----- Original Message ----- > From: João Mesquita > Sent: 10/19/11 10:55 PM > To: freeswitch-dev(a)lists.freeswitch.org > Subject: Re: [Freeswitch-dev] get variable value > > >From your email, I am assuming you are trying to get a variable using ESL? > If so, custom variables are prefixed with variable.

FreeSWITCH dialstring/channel variables
by lg 20 Oct '11

20 Oct '11

One quick question here. Is it any dialstring to control dial function? Like as,i would change the dial legs sequence as dial caller number first and then when caller pickup the call, dial the called destination number ( as the same as "originate dial_string destination_number" function). Your hint or short response would be much appreciated. Thanks, Grant

Re: [Freeswitch-dev] Couple of questions about esl in C

I want to try one more thing to see if it solves my problem int response_timeout = (10 * 1000); esl_status_t status; status = esl_recv_event_timed(call_info->global_handle, response_timeout, 0, xxxxx); The note for the last paramter is: \param[out] save_event If this is not NULL, will return the event received What type of varible do I need to pass as the paramter and where will the return data go and how to access it. I have noticed this channel variable Application-Response: FILE%20PLAYED which possibly might indicate playback completion? > ----- Original Message ----- > From: Michael Collins > Sent: 10/19/11 10:30 PM > To: freeswitch-dev(a)lists.freeswitch.org > Subject: Re: [Freeswitch-dev] Couple of questions about esl in C > > On Wed, Oct 19, 2011 at 12:21 PM, adam harris <admharris(a)gmx.com> wrote: > > > A few questions about esl in C > > > > 1, After sending api playback command I want to wait until the file is done > > playing.

A few questions about esl in C 1, After sending api playback command I want to wait until the file is done playing. How do I do this is C 2, Whats the proper way to use esl_recv_event_timed and esl_recv_even I tried it like this esl_recv_event_timed(call_info->global_handle, 10, 0, NULL); but that printed the complete event on screen. I want to do this in a while loop to check for event-name Can you please resend this to freeswitch-dev(a)lists.freeswitch.org -MC On Wed, Oct 19, 2011 at 9:10 AM, adam harris <admharris(a)gmx.com> wrote: After sending api playback command I want to wait until the file is done playing How do I do this is C
