[Freeswitch-dev] FreeSWITCH on Windows crashing when doing deflect/REFER
by Peter Olsson 12 Oct '09

12 Oct '09

I have a problem with FreeSWITCH (r13175) when using REFER. If running inside Visual Studio, everytime (during the REFER) I get a "...has triggered a breakpoint". It's possible to click continue to go on, but eventually (another 2-3 calls) FreeSWITCH crasches completely. When running outside Visual Studio I get a crasch after maybe 10 calls. Another interesting scenario is when running outside the debugger and I enable siptracing it's much more stable - even though it crasches eventually - this is what makes me wonder about mutexes... I've tracked it down to calls to malloc() and calloc() which in 100% of the cases is in the top of the call stack. My thought is that it might be related to a mutex issue somewhere. Below I've copied the call stack from two times it's happened to me. These are the most common traces, but sometimes it's a malloc being called from the sqlite lib. But so far I always think it's been related to a malloc/calloc. These things have occured in a couple of other places as well, for instance when a SIP registration fails (registering to an external server) with error 404 I also get a breakpoint triggered, but I don't think that has caused any crasches yet. I've tried to debug this on my own, but so far I didn't find anything, so that's why I'm asking you guys :) I think I'm going to try the same on Linux as well, and see if it works differently there. If you need more info, please let me know, I'll try to help out as much as possible. I thought I'd post this here first, if you have any ideas. If not I'll file a Jira for the issue. ----- ntdll.dll!DbgBreakPoint() [Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll] ntdll.dll!RtlpNtMakeTemporaryKey() + 0x3eee bytes

[Freeswitch-dev] Originating from an event.
by Kevin Snow 10 Jul '09

10 Jul '09

Hi, I¹m writing my own module and have a situation where I need to connect two endpoints in response to an event. I have the custom event tied into my module and I know my endpoints that I need to connect but it¹s not clear to me how to set up this connection. It appears that I cannot (or at least don¹t want) to set up this connection on the thread the event came in on as that stalls other events from coming in. I think I need to create a new thread and session then use switch_ivr_originate and bridge the two. That however seems easier said than done, so I must be missing something. Switch_thread_create looks fairly straight forward but in the examples of it they all are used in situations where a session already exists. It¹s uses the pool from that session. In the event handler I don¹t have any session. I need to set the entire phone call/session up from scratch. I keep looking for a ³switch_create_session² like call to setup this but that doesn¹t exist. Clearly I¹m going about it wrong. Are there any examples or docs on how to do this programmatically? I¹ve search and can¹t find anything like this. I¹m fairly new to FS but hopefully this isn¹t a total newbie question and that it makes sense. I¹m excited for ClueCon, that¹ll shed a lot of light on FS for me. Kevin

[Freeswitch-dev] mod_java startup/shutdown hooks
by String Larson 30 Jun '09

30 Jun '09

I did some work on mod_java to allow for a user defined method to be called on startup and shutdown. The methods are defined in java.conf.xml: <startup class="some/path/foo/Control" method="startup" arg="start up arg"/> <shutdown class="some/path/foo/Control" method="shutdown" arg="shutdown arg"/> I'd like to make this avail. to the FS codebase. Thoughts ? -str

[Freeswitch-dev] mod_managed not working from dialplan but working from console
by rentmycoder rentmycoder 30 Jun '09

30 Jun '09

I use Freeswitch 1.0.4pre3 on CentOS 5.3 with Mono2.4 compiled from source. I've compiled the Freeswitch.Managed.dll on linux using mono's compiler... When I try to execute the built in test function from the console, it works: freeswitch@internal> managed ApiDemo 12 ApiDemo executed with args '12' and event type API. When I add it to an internal extension like this, <extension name="3000"> <condition field="destination_number" expression="^(3000)"> <action application="answer"/> <action application="managed" data="ApiDemo 12"/> </condition> </extension> and dial 3000 from a softphone: 2009-06-30 12:42:46 [ERR] switch_cpp.cpp:1119 console_log() Could not find function ApiDemo. 2009-06-30 12:42:46 [ERR] mod_managed.cpp:405 managed_app_function() Application run failed for ApiDemo 12 (unknown module or exception). I'v tried to load the assembly using loadmanaged also, it works from the console (managedload FREESWITCH.), but does not work from the dialplan Please help!

[Freeswitch-dev] Question regarding Misc. Dialplan Tools eavesdrop
by Ian Quek 29 Jun '09

29 Jun '09

Hi, I have a question regarding the eavesdrop extension that FreeSwitch has. I'm currently looking at http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_eavesdrop. From what I gather reading the page, you enable eavesdrop/call barge by making the changes specified in "examples" to the default.xml file. However, I'm interested in knowing more about how this particular module works, and how I can use its capabilities. Is there any further documentation for this feature, and where can I find such documentation? For example, in the example provided, if I dial 881001, am I actually making the call to 1001, or am I simply listening to any call 1001 is making? Does this extension allow me to say, dial 881001, and have the phone that I'm using connect to 1001, and record the call I'm making to 1001 in the FreeSwitch server? thanks -Ian

Re: [Freeswitch-dev] Manually downloading libraries
by Ian Quek 29 Jun '09

29 Jun '09

I managed to successfully compile and run FreeSwitch on my non-internet enabled box. I did this in Red Hat Linux 5 as well as Windows Vista. For Red Hat, I only needed the following additional libraries: unixODBC-2.2.11-7.1.i386.rpm unixODBC-devel-2.2.11-7.1.i386.rpm For Windows Vista, I built FreeSwitch on an internet enabled machine, then copied the libs/ directory to the non-internet enabled machine. These were the additional packages that were needed: communicator_semi_6000_20080321.tar.gz flite-1.3.99.tar.gz howl-1.0.0.tar.gz lame-3.97.tar.gz libogg-1.1.3.tar.gz libshout-2.2.2.tar.gz mpg123.tar.gz pocketsphinx-0.5.99.tar.gz pthreads-w32-2-7-0-release.tar.gz sphinxbase-0.4.99.tar.gz tiff-3.8.2.tar.gz These files were extracted into the libs/ directory prior to compiling on the non-internet enabled machine. -Ian Date: Wed, 24 Jun 2009 22:34:41 -0700 From: William King <quentusrex(a)gmail.com> Subject: Re: [Freeswitch-dev] Manually downloading libraries To: freeswitch-dev(a)lists.freeswitch.org Message-ID: <4A430C71.4030203(a)gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Which libraries, and files need to get downloaded? and where are they downloaded too?
