Command-line windows build?
by Josh Rivers 06 Nov '09

06 Nov '09

I've spent a couple of nights trying to get FS to build on Win32 using msbuild against the .sln file. Debug builds seem to fail in spidermonkey, and release builds fail in util.vbs. Everything builds fine if I do it in Studio, it just doesn't build from the command line. Is anybody doing an automated build of FS on windows? If so, are you using any tricks to get it compile or am I missing something obvious? Thanks, Josh ps. I see a binary build reference in the Wiki. Is the code to build / package that checked in somewhere?

Libraries (http://files.freeswitch.org/ or system)
by Trever L. Adams 05 Nov '09

05 Nov '09

Hello everyone, I have tried to find this answer, but have been unable to do so. Fedora has most of the libraries and programs used by freeswitch. Can I use the system ones or do I need to use the ones at files.freeswitch.org? I understand they are needed on windows for compilation reasons, but I am interested in Linux.

execute api after conference
by vip killa 04 Nov '09

04 Nov '09

I'm trying to figure out how to execute an API command such as a lua script after a user has connected to a conference. for example, an extension is executed and the user is connected to a conference: <action application="conference" data="live@home+flags{moderator}"/> after the user has connected to the conference, i want a lua script to run. is this possible? everything i've tried results in executing the lua script before the user is actually connected to the conference.

FW: Visual Studio 2008 Pro SP1: switch_loadable_module.c:871 Error Loading module .... **dll sym error [127l]
by Alex To 04 Nov '09

04 Nov '09

Sorry, I figured it out by myself. It was because my code file is mod_mymodule.cpp. I changed it to mod_mymodule.c and the module loaded file. So I take it as FS accepts only C library but not C++ ?

I tried to create a new end point module by copying the mod_skel to mod/endpoints/my_module folder. I modified "skel" to my module name and basically I leave no codes in the load function, just a few lines to test if the new module is working.

Btw, I looked at mod_sofia and mod_iax, this line of code could compile in those 2 modules. modem_endpoint_interface = switch_loadable_module_create_interface(*module_interface, SWITCH_ENDPOINT_INTERFACE); The same line of code couldn't compile in my module coz VS complains: cannot convert from void* to switch_endpoint_interface_t*. I know C++ require more type-safe conversion than C but anyone got the same error? And how would I search in the mailing list ? Sorry for this dumb question but I can't seem to find out how to search in the archives. For now, before posting anything, I need to try to browse through all the postings first, which is quite tedious to do. Regards Alex To

Re: [Freeswitch-dev] mod managed, cant receive events thru EventReceivedFunction callback
by Alex To 03 Nov '09

03 Nov '09

Hi, I would like to raise this question again since it doesn't seem to have an answer yet. I built a .NET module which implements IAppPlugin and IApiPlugin. I looked at the /contrib/verifier/eventsocket and it is actually the client to connect to FS through mod_event_socket (correct me if I'm wrong here). I believe Andrew's concern was how to receive events through EventReceivedFunctionCallback but not connect to FS and receive event via TCP/IP. I would want to implement a .NET module that acts like an endpoint. Could someone show me the direction of how to hook up handlers like it is done in native C++? How would I read the incoming audio data and how would I send audio as an outgoing stream. I setup the .NET module and dial plan so that the Run() method in my module is invoked whenever a call is bridged to my endpoint. The ParkingLot and Demo script sample does enlighten me a little but I still have no clue how would I go about the audio stream after I call session.Answer(). Any help would be greatly appreciated. Best Regards Alex To

Question about threading model, Does it restrict the concurrent capability of FS？
by Lei Tang 02 Nov '09

02 Nov '09

Hi All, As I known FS usually use two thread to handle one call, one for inbound and one for outbound. In 32bits system, a process's memory is limited to 2GB, So I think a FS process can create up to 500 threads, and handle 250 call in the same time. Is it right? How if FS run in 64bits system? Best Regards! -- Lei.Tang lei.tlfly(a)gmail.com
