[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] Issues building freeswitch (git-co) on Nexenta CP3
by Thomas Haggett 02 Sep '10

02 Sep '10

Hi, Having run away from OpenSolaris (but not too far) I've recently migrated to Nexenta and had a go at building / running FreeSWITCH. I run a few low-throughput SIP-based projects and have thus far been running Asterisk (is that a dirty word in these parts?) on a Debian VM which horribly exploded when I tried to build on nexenta. Not being much of a fan of Asterisk, I decided to give FS a go. For reference, my git repo HEAD is at 6cdd3e2a2e4677b061b9fbb9ee516fae9601cd16. It wasn't a clean build, per se, but I managed it with a couple of compile non-default switches and a slight hack that I figured I'd offer back for comment / improvement; * configure guessed my platform as "i386-pc-solaris2.11" which caused a multitude of issues, principally bad linker behaviour meaning the libtool libraries failed with gcc complaining about bad file format (or something along those lines) for the generated .lo files half way through the build, as well as some atomic lock symbols missing from the c-library which I believe are emulated in libraries for i386 processors, but present on the amd64 host. (not an expert on these things). These were fixed (after a while picking through non-obvious errors) by simply adding the configure arg --build=amd64-pc-solaris5.11 Apologies if this is obvious to some, but it wasn't to me and took a while to figure out. * a couple of modules wouldn't build cleanly but because I didn't require them I just commented them out from modules.conf. Trying to be useful I tried to build as many as I could and ended up with these modules removed: #applications/mod_osp #applications/mod_hash #applications/mod_spandsp #applications/mod_memcache #codecs/mod_sangoma_codec #codecs/mod_dahdi_codec ##directories/mod_ldap #endpoints/mod_dingaling ##endpoints/mod_portaudio #endpoints/mod_loopback ##endpoints/mod_alsa ##endpoints/mod_opal ##endpoints/mod_skinny ##endpoints/mod_skypopen #endpoints/mod_h323 ##../../libs/openzap/mod_openzap ##../../libs/freetdm/mod_freetdm #asr_tts/mod_unimrcp #asr_tts/mod_flite #asr_tts/mod_pocketsphinx #asr_tts/mod_cepstral ##asr_tts/mod_tts_commandline #event_handlers/mod_erlang_event #formats/mod_portaudio_stream #languages/mod_python #languages/mod_spidermonkey #languages/mod_perl #languages/mod_java #languages/mod_managed #xml_int/mod_xml_ldap I believe a lot of these were simply missing 3rd party libraries but, since I didn't need them, I didn't spend much time working it out. I can do this if anyone is particularly interested. * I had a couple of missing symbols (herror was one) which was simply resolved by adding LDFLAGS='-lresolv' to the configure command * I had some issue with compiler warnings complaining about C-standards (don't have the error to hand), but I sorted this by simply adding CFLAGS='-fgnu89-inline', again to the configure. * The only other fix was a missing definition for strcasecmp, which I struggled to sort the problem as <strings.h> was included in the appropriate files. I'm a little ashamed to say that I sorted this out by simply adding these library prototypes (lifted from strings.h) to libs/esl/src/include/esl.h: extern int ffs(int); extern int strcasecmp(const char *, const char *); extern int strncasecmp(const char *, const char *, size_t); After this the build proceeded (after quite some time) without issue and installed (and ran) fine. If anyone wants the specific errors in each case, I'll run through a build and try to reproduce and also file a bug if this is appropriate. Now to figure out the Freeswitch configuration :) Thomas.

[Freeswitch-dev] how to use switch_json?
by Seven Du 01 Sep '10

01 Sep '10

Hi, I'm developing a client based on FSComm (using QT), I need to parse some JSON string, as FS already has json libs build in so I don't want link to other json libs. I used cJSON_Parse, but when I tried to link with libfreeswitch, but it cannot found cJSON_Parse Undefined symbols: "_cJSON_Parse", referenced from: I listed functions using nm -gfj libfreeswitch.dylib (on mac), there are no json related And there's no libjson in /usr/local/freeswitch/lib So, where is it? As event socket support json format it should be somewhere. I build mod_curl, then it download json lib again. I'm on git version a few days ago. Thanks. -- Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn

[Freeswitch-dev] WANTED: Cookbook recipes
by Michael Collins 31 Aug '10

31 Aug '10

Hello all! We are investigating the possibility of writing a cookbook for FreeSWITCH. We would like to invite the community at large to submit ideas for recipes. I have started a wiki page here: http://wiki.freeswitch.org/wiki/Cookbook Please add your cookbook wishlist items here. If you have an actual recipe that you'd like to contribute then mention that fact as well. We are not looking for the actual recipes themselves but rather the ideas for the recipes. I've added a number of sections on the wiki but feel free to add another one if I have missed a category of recipes. Any questions please let me know! Thanks, MC

[Freeswitch-dev] FreeSWITCH reads commented lines from vars.xml
by Oleg Khovayko 30 Aug '10

30 Aug '10

Hi all, Today I found bug in the FreeSWITCH v 1.0.6. When I write in the file vars.xml following codecs config lines {{{ <X-PRE-PROCESS cmd="set" data="global_codec_prefs=PCMU,PCMA"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA"/>  }}} FreeSWITCH reads config values from the comments, and, since comments located after correct values, then values from comments overwrites correct config values. and command: sofia status profile internal shows: CODECS IN G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM,H264,H263,H263-1998 CODECS OUT G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM,H264,H263,H263-1998 ATTN: After modify vars.xml, for see this bug, need perform full restart of freeswitch, by commands like: /usr/local/etc/rc.d/freeswitch stop /usr/local/etc/rc.d/freeswitch start If you just execute "reloadxml" in the fs_cli, codecs lines will be unchanged.
