[Freeswitch-dev] FreeSWITCH Cookbook Question: Pocketsphinx
by Michael Collins 14 Jun '11

14 Jun '11

Hello all! I am looking for examples of mod_pocketsphinx being used in a real-world application. If you are using pocketsphinx ASR for something useful and can share some configs I would appreciate it. I'm soliciting ideas on how to make the pocketsphinx recipe in the cookbook be as truly useful as possible. I don't personally use it for anything and I've only seen the pizza demo in action, so I'm asking our intrepid community members for some thoughts. Email me off list, please. Thanks! -Michael

by Michael Collins 11 Jun '11

11 Jun '11

Hey all, I am working on the FSCB and I could use some of your real-world fax examples. I'm looking for anything like these: Inbound fax to email/PDF Outbound fax examples (scripts, etc. - whatever you do to make it easier for your users to send faxes thru FS) T.38 config examples and reports on symptoms/issues you had to overcome to make it work I will gladly accept any information you have, even if it's just raw dumps of scripts, XML configs, etc. Shoot them to me off-list. Thanks! -MC

[Freeswitch-dev] Build problems under Windows 7
by Mark Sobkow 09 Jun '11

09 Jun '11

I'm just setting up a new Windows 7 box as an experimental upgrade to our usual Windows XP and Linux/Ubuntu environments. Windows 7 Ultimate (64 bit) Visual Studio 2008 Standard SP1 (C#, C++, and VB) InnoSetup installed FS Git installed to C:\freeswitch I'm not trying to do a setup build yet, just a standard build. However, I'm having problems with the JSON library. It compiles Ok under XP, but gives VBscript errors under 7. The only thing difference I can think of that might be relevant is I have VB6 installed on the XP box, but I doubt that's actually required for VBS. At line 135 of the script, it's trying to create a .bat file in the directory. The only thing I can think of is that maybe the random number generation isn't as random as one would like, resulting in it re-using the same script name and running into a "file exists" type of problem. Any suggestions?

[Freeswitch-dev] Custom date/time pronunciation
by Steve Sims 08 Jun '11

08 Jun '11

I've written a patch (http://jira.freeswitch.org/browse/FS-1889) to allow more control over date and time pronunciation from the 'say' application which allows Asterisk SayUnixTime style constructs to be pronounced. Usage is based on strftime formatting codes with additions to pronounce words like 'hours', 'minutes', 'at' etc. so for example: <action application="say" data="en custom_date_time pronounced %H%h%M%n:${strepoch()}"/> It's currently only available for mod_say_en as I don't have any other human language skills to be sure of changing the other mod_say_xx's without causing a regression. So my question is, is it going to be OK to submit this change for mod_say_en only? Otherwise, would anybody like to help me port it to other language 'say' modules - it's not doing anything particularly smart, just 'say'ing files based on the order of formatting codes passed in for the most part? The most recent proposed patch is fs1889_2011-06-08.txt on the above mentioned jira if you want to have a look. Cheers, Steve

[Freeswitch-dev] Getting a 502 Bad Gateway error trying to do a windows build
by Mark Sobkow 07 Jun '11

07 Jun '11

I'm trying to do a windows build, but when the build tries to download files from http://files.freeswitch.org/downloads/libs/pthreads-w32-2-7-0-release.tar.gz (for example), it gets a 502 Gateway error, resulting in 1K files that can't be properly processed. How do I resolve this?

[Freeswitch-dev] missing Diver sion header in 300, 302 message
by Tihomir Culjaga 04 Jun '11

04 Jun '11

hello, i found that FS doesn't transparently map Diversion header from INVITE to 300|302 message in a case of diversion. i have changed mod_sofia.c to adjust this: char *added_headers = sofia_glue_get_extra_headers(channel, SOFIA_SIP_HEADER_PREFIX); --- 2026,2037 ---- if (argc > 1) { nua_respond(tech_pvt->nh, SIP_300_MULTIPLE_CHOICES, SIPTAG_CONTACT_STR(dest), ! TAG_IF(!zstr(extra_headers), SIPTAG_HEADER_STR(extra_headers)), ! TAG_IF(!zstr(added_headers), SIPTAG_HEADER_STR(added_headers)), TAG_END()); } else { nua_respond(tech_pvt->nh, SIP_302_MOVED_TEMPORARILY, SIPTAG_CONTACT_STR(dest), ! TAG_IF(!zstr(extra_headers), SIPTAG_HEADER_STR(extra_headers)), ! TAG_IF(!zstr(added_headers), SIPTAG_HEADER_STR(added_headers)), TAG_END()); } Now 300|302 message contains the original header that was present in INVITE. since i didn't get any response whether this is a "feature" or a bug ... i went into the code and changed it myself. Please check the patch attached and see if it is possible/feasible/acceptable merge it into FS trunk. Regards, Tihomir. BTW: macros are cool while bringing headache in the same time :=)
