by lakshmanan ganapathy 11 Dec '10

11 Dec '10

Hi all, When using ftmod_libpri, if a incoming call comes without "Channel Identification" ( in SETUP packet ), then the call didn't get proceeded. I've taken some code snippets from ftmod_isdn and I applied it in ftmod_libpri. I've tested it and in my setup it works fine. I've attached the patch here. Please verify it and found ok commit it. regards, Lakshmanan G.

[Freeswitch-dev] please shed me light on code reading
by jesse 25 Nov '10

25 Nov '10

hi, Any expert can shed me some light on quick code understanding? thanks in advance! suppose I dial 88<1001> to spy on extension user 1001. and 5 minutes later 1001 calls 1002. <extension name="userspy"> <condition field="destination_number" expression="^88(.*)$|^\*0(.*)$"> <action application="answer"/> <action application="userspy" data="$1(a)192.168.1.1"/> </condition> </extension> in event_handle(...) of mod_spy.c. -- Whats is the reason that we need to call process_event for both event and peer_event? is not processing event for call leg-a 's bridge enough? it seems mod_spy.c in 1.0.6 version doesn't process peer_event. static void event_handler(switch_event_t *event) { if (process_event(event) != SWITCH_STATUS_SUCCESS) { const char *peer_uuid = switch_event_get_header(event, "variable_signal_bond"); ... if (peer_event) { process_event(peer_event); } } } http://svn.freeswitch.org/svn/freeswitch/trunk/src/mod/applications/mod_spy…

[Freeswitch-dev] nolocal exports from dial plan
by Dino Korah 25 Nov '10

25 Nov '10

Guys, When I export a variable as nolocal, is it intended to prefix "nolocal:" for that variable on A, when that appears in the CDR? Or is it a glitch? Ref: src/mod/applications/mod_dptools/mod_dptools.c line 889 Here if you check, the export seems to ignore the local variable altogether. I am quite new to freeswitch; any help much appreciated. Many thanks, "dk"

[Freeswitch-dev] Compiling on FreeBSD
by Adrian Gschwend 25 Nov '10

25 Nov '10

Hi group, I use Freeswitch on FreeBSD for ages now, always trunk which I compile every few weeks. Unfortunately it doesn't compile anymore for a while, it fails in mod_spandsp I checked the docs according to: http://wiki.freeswitch.org/wiki/Installation_Guide#FreeBSD http://wiki.freeswitch.org/wiki/Mod_spandsp so I compiled both graphics/tiff-4.0.0 and graphics/jpeg-8_3, I'm on 8.1-RELEASE But it doesn't find jpeg, like the possible error stated on Mod_spandsp page. But unless I completely miss something here it *should* be installed (in terms of the port is definitely there). -- [...] Creating mod_spandsp.la /usr/bin/ld: cannot find -ljpeg quiet_libtool: link: gcc -shared .libs/mod_spandsp_la-mod_spandsp.o .libs/mod_spandsp_la-udptl.o .libs/mod_spandsp_la-mod_spandsp_fax.o .libs/mod_spandsp_la-mod_spandsp_dsp.o .libs/mod_spandsp_la-mod_spandsp_codecs.o -Wl,-rpath -Wl,/usr/local/src/freeswitch/.libs -Wl,-rpath -Wl,/usr/local/freeswitch/lib -L/usr/local/src/freeswitch/libs/apr-util/xml/expat/lib/.libs -L/usr/local/src/freeswitch/libs/apr/.libs -L/usr/local/src/freeswitch/libs/tiff-3.8.2/libtiff/.libs -ljpeg /usr/local/src/freeswitch/.libs/libfreeswitch.so -L/usr/local/src/freeswitch/libs/apr-util/xml/expat/lib /usr/local/src/freeswitch/libs/apr-util/xml/expat/lib/.libs/libexpat.a /usr/local/src/freeswitch/libs/apr/.libs/libapr-1.a -lcrypt -lpthread /usr/local/src/freeswitch/libs/spandsp/src/.libs/libspandsp.a -L/usr/local/src/freeswitch/libs/tiff-3.8.2/libtiff /usr/local/src/freeswitch/libs/tiff-3.8.2/libtiff/.libs/libtiff.a -lz -lm -lssl -lcrypto -lncurses -Wl,-soname -Wl,mod_spandsp.so -o .libs/mod_spandsp.so gmake[4]: *** [mod_spandsp.la] Error 1 gmake[3]: *** [mod_spandsp-all] Error 1 gmake[2]: *** [all-recursive] Error 1 -- Any FreeBSD user which can compile that ATM?

[Freeswitch-dev] issue ESL-52: event nitifications filters
by Alex Deiter 23 Nov '10

23 Nov '10

Hi, Could you please review issue ESL-52 ? We are used FreeSWITCH with BigBlueButton and found problem with ESL events. Each new filter loses the previous filter. Example: % ./fs_cli -H 127.0.0.1 -p ClueCon ... freeswitch@127.0.0.1@internal> /event all +OK event listener enabled plain ===> now received ALL events Event-Name: HEARTBEAT Event-Name: RE_SCHEDULE Event-Name: HEARTBEAT Event-Name: RE_SCHEDULE ===> add filter ===> now received ONLY HEARTBEAT events freeswitch@127.0.0.1@internal> /filter Event-Name HEARTBEAT +OK filter added. [Event-Name]=[HEARTBEAT] ===> add another filter ===> now FreeSWITCH forgotten about the previous filter and used only last filter freeswitch@127.0.0.1@internal> /filter Event-Name RE_SCHEDULE +OK filter added. [Event-Name]=[RE_SCHEDULE] Event-Name: RE_SCHEDULE Event-Name: RE_SCHEDULE Event-Name: RE_SCHEDULE This behavior was noted after FreeSWITCH snapshot 12-Nov-2010 FreeSWITCH snapshot 15-Oct-2010 works as it should: each new filter was added to the existing filters. Could you please explain this ? Thanks a lot! -- Alex Deiter

[Freeswitch-dev] Commercial module development?
by raul2r2 raul 23 Nov '10

23 Nov '10

Hi... I'm thinking in developing a new module for Freeswitch for commercial use and distribution. It would be a new end point module based in a propietary binary protocol. And here the problem raise, because I'm a bit confusing about MPL license and its implications. Would this module be considered as a derivate work?. If it's considered as a derivate work, is it any kind of commercial license for freeswitch?. and the last question, if any of this is possible, could I statically link Freeswitch core or some of its modules in my application if I don't modify its source code?. Regards,

[Freeswitch-dev] VAD/ CNG question
by Andy Pyles 23 Nov '10

23 Nov '10

I setup the following scenario: A calls FS, FS plays back a wav file. I turned on the following channel variables: rtp_enable_vad_in=true rtp_enable_vad_out=true My question is where in the code are these channel variables defined? Specifically, I'd like to modify the silence threshold that is used. For my purposes, I'd like to tune the threshold to something more agressive than the default value. I'm using g.711U codec. thanks, Andy
