ReloadXML takes very long time
by Yiftach Golan 26 Oct '12

Hi FreeSWITCH community, My name is Yiftah and I am working for ChooChee which is a hosted PBX solution company We have been using FreeSWITCH for almost 2 years and we added a lot of code changes to the core and to the different modules Lately we have made a decision to get more close to the community so that we can enjoy the bug fixes and the new feature from the community and we can contribute our knowledge and bug fixes I would please like to start with a very basic question : We are using dialplan xmls in order to load the configuration, we have a lot of users on each freeswitch (+4k), it took a very long time for the configuration to load (around 5 minutes) during this time no new calls could be served by FreeSWITCH In order to solve this problem we introduce reload xml that accepts file names and has the ability to load just one file name into the memory (we achieved 10ms loading time instead of 5 minutes) The problem is that we had to introduce a lot of code in order to solve this problem, has anyone else encounter this problem? we do not want to use mod_xml_curl as we want to take care bringing the file to the machine Another approach that we thought is that a database might be much better fit in here, because every xml update includes the entire tenant (business) and has the potential in harming other users in the same tenant, also DB has much higher capacities then XMLs, did anyone think of enabling MySQL as a directory of parameters instead of xml? Thanks, Yiftach.

FreeTDM and Brazil DTMF - CallerID Detection
by Antonio Modesto 26 Oct '12

26 Oct '12

Hi, I would like to know if I can help, in someway, to implement this feature in FreeTDM. Today, if we use an analog card here in Brazil, we have to use dtmf to fsk converters to enable the callerid detection, both on freeswitch and asterisk. If there is anybody who works on FreeTDM / FreeSWITCH project that is available to help us with this, I can give access to an machine with analog boards, I have some knowledge in C programming too. Thanks.

This just started happening, both on 1.2.3 and HEAD. Why would I get this if FreeSwitch is started with -NONAT? Mario G sofia.c:1428 nua_i_outbound: unknown event 8: 102 NAT binding changed

<condition/> and custom functions in lua or p-languages?
by Scott 25 Oct '12

25 Oct '12

We need to write a function, usable in the XML dial plan, that tests the inbound CID (not destination_number) against a "white list." Something on the line of,,, <condition field="ISWHITE(${caller_id_number})" expression="true" > Question: In such a use case, must ISWHITE() be a custom application/mod written in C, per skel.c, or can it be a script written in lua or p-language or the like? It's clear from wiki and docs we've seen that <action ... /> can have lua or p-language scripts; but it is not clear about the <condition ... /> clauses and where to locate and "hook" them in. Guidance and any pointers to docs/examples greatly appreciated. With thanks, /S

Help writing a simple JS script
by George Diamantopoulos 25 Oct '12

25 Oct '12

Hello, I've been trying to write a simple JS script, which is called from within the XML dialplan, in order to convert the value of ${created_time} to something more meaningful than UNIX time in ms. The problem is when I try to print something to the console (see log application below), I get NaN (not a number) for variable ${created_date}, even though I don't want a number (a string is fine, I tried enforcing this with toString()). Moreover, you'll notice I've left out var month = date.getMonth();, because if I don't I get the following error: TypeError: date.getMonth is not a function. I can't figure out why, it's documented in JS in the date object, and the syntax is identical to other functions I use to acquire object values. Any hints would be greatly appreciated, I've been trying different code variations for over two hours now and I'm stuck. Thanks. Here's the call in the dialplan: <action application="javascript" data="unixtocal.js $created_time"/> And here's the JS script itself: var date = new Date(argv); var hours = date.getHours(); hours = hours.toString(); var minutes = date.getMinutes(); minutes = minutes.toString(); var seconds = date.getSeconds(); seconds = seconds.toString(); var ms = date.getMilliseconds(); ms = ms.toString(); var year = date.getFullYear(); year = year.toString(); var day = date.getDate(); day = day.toString(); session.execute("set", "created_year="+year); session.execute("set", "created_date="+day); session.execute("set", "created_hours="+hours); session.execute("set", "created_minutes="+minutes); session.execute("set", "created_seconds="+seconds); session.execute("set", "created_ms="+ms); Then the dialplan takes over again, for example: <action application="log" data="INFO Date is ${created_date}"/>

ftmod_libpri won't load (undefined symbol: ftmod_pritap_module_interface**)
by George Diamantopoulos 25 Oct '12

25 Oct '12

Hello all, I've been trying to compile freeswitch and freetdm with pritap support. Everything seems to be going fine, but the module (ftmod_pritap) won't load. I've been told this could be due to version mismatches between freeswitch and freetdm source, but I'm compiling both from git 1.2-stable. I intend to use this with Sangoma's wanpipe TDM Voice API and the driver configured in High Impedence mode (in conjunction with a 2-span E1 sangoma card and a tapping module). The error I get is: freeswitch@modrec> load ftmod_pritap 2012-10-23 12:45:24.284094 [INFO] mod_enum.c:871 ENUM Reloaded 2012-10-23 12:45:24.284094 [INFO] switch_time.c:1163 Timezone reloaded 530 definitions +OK Reloading XML -ERR [module load file routine returned an error] 2012-10-23 12:45:24.284094 [CRIT] switch_loadable_module.c:1310 Error Loading module /usr/local/freeswitch/mod/ftmod_pritap.so **/usr/local/freeswitch/mod/ftmod_pritap.so: undefined symbol: ftmod_pritap_module_interface** STEPS TO REPRODUCE: Start with a clean debian 6.0.6 installation and then: apt-get install subversion git apt-get build-dep asterisk (# Hopefully asterisk and freeswitch share some dependencies) apt-get -y install gcc g++ automake autoconf libtool make libncurses5-dev flex bison patch libtool autoconf linux-headers-$(uname -r) (wanpipe build deps) apt-get remove libpri-dev libpri1.4 (I will be compiling patched libpri with tapping support later) wget ftp://ftp.sangoma.com/linux/current_wanpipe/wanpipe-3.5.28.tgz svn checkout http://svn.digium.com/svn/libpri/team/moy/tap-1.4 (libpri patched with tapping mods) cd tap-1.4/ make make install cd .. tar xzfv wanpipe-3.5.28.tgz cd wanpipe-3.5.28/ ./Setup install (select option 1, for TDM voice API module configuration - required for use by freetdm pritap module - I think) cd .. git clone -b v1.2.stable git://git.freeswitch.org/freeswitch.git cd freeswitch/ ./bootstrap.sh ./configure make make install cd libs/freetdm/ ./configure --with-pritap --prefix=/usr/local/freeswitch make make install /usr/local/freeswitch/bin/freeswitch load ftmod_pritap EXPECTED BEHAVIOUR: ftmod_pritap should load successfully.

Are both these off by default in Freeswitch? If not how would I disable the comfort noise and vad for all calls?

javascript for ppc
by Ken Kelly-Turner 24 Oct '12

24 Oct '12

Hi all, cross-compiled freeswitch onto my ppc board using the wiki guide for cross-compiling for arm. I found that javascript didn't work on ppc either and I was wondering if anybody had a work-around to get it to build? Thanks, Ken
