Conference recording pause/resume problem
by Mariusz Czulada 13 Jul '12

13 Jul '12

Hi, I try to prepare a patch which allows to pause/resume a given recording. I'm in the middle of the road: pause is working, by resume - not :(. I'd like to ask for your help in finding a problem. I'm not sure if I handle member and file flags in the thread sub correctly. BTW. I lost some time playing with member-fnode until found fh in conference_record_thread_run is a proper handler. What is the conference_file_node_t member->fnode used for, if not for handling a recording file? Regards, Mariusz

questions about making a new endpoint
by Seven Du 29 Jun '12

29 Jun '12

Hi, I'm working on a mod_rtsp endpoint the idea is to stream sip video to a rtsp client such as VLC and also a sip client could "call" a rtsp camera later. I copied some codes from mod_sofia and it is too long to understand for me so I'd like to get some inputs either highlight me how to do or point out where to read from mod_sofia. 1) VLC "calls" in as a-leg and bridge to a sip client with video(or play_fsv), I made it sort of working now, but - How to disable the read_frame and read_video frame io_routine ? I set them to NULL and it fails on read, so I made a fake read function there, kind of ugly. - I hard coded to H264 and I can see video on VLC, I'd like to do like sip later negotiation then when b-leg sip client offers SDP and offer to a-leg when DESCRIBE - looks like switch_io complains when no audio codec, is it possible to do video only calls? or is it possible to set audio and video rtp to a different path ? 2) Call a rtsp camera would be easy later 3) Maybe a client can call in and record? I don't have such a client. I would like to share the code later if others interested on this. Thanks, Seven. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow (http://www.sparrowmailapp.com)

ESL events, header data in non-ascii characters and unicode hell
by Anton VG 29 Mar '12

29 Mar '12

Guys, Some users enter their name in unicode (non ascii chars) - russian for example or french When using Python ESL in Python3 - I get this weird behavior. ESLevent already attempted to be returned as a unicode str, and damn Py3 attempts to unicode it before I can catch an exception in the ESL.py code and remove the non ascii chars or handle it another way. (python 2 have been just passing the bytes over) File "/home/anton/GIT/auth_server/ESL/ESL.py", line 78, in getHeader def getHeader(self, *args): return _ESL.ESLevent_getHeader(self, *args) UnicodeDecodeError: 'utf8' codec can't decode byte 0xef in position 1: invalid continuation byte While the data is ascii or unicode correct, all OK. Please help determine where I can tap in to have headers data to be cast as bytes before passed over to PythonLIB As ESL and other libs are automatically compiled using SWIG - I have no idea yet where to look at.

uuid in mod_spandsp_fax.c
by Anita Hall 28 Mar '12

28 Mar '12

Hi This is my first post to dev mailing list and I am pretty excited :) I want the uuid prefixed for spandsp internal messages in the log. I noticed these are the ones printed by line 285 in mod_spandsp_fax.c switch_log_printf(SWITCH_CHANNEL_LOG, fs_log_level, "%s", msg); The lines which do print the uuid use the session variable switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(session), SWITCH_LOG_DEBUG, "=== Negotiation Result =============\n"); So basically, I have to modify the function void spanfax_log_message(int level, const char *msg) so that it accepts user_data from which I can get the session. What other change do I have to do to make sure that this new function definition will be used correctly else where? And, if I am not thinking in the right direction, is there a simpler way to achieve this ? Thanks. regards, Anita

Open Bugs on Jira and Call for help
by Ken Rice 28 Mar '12

28 Mar '12

If you have open bugs on Jira, please make sure they are up to date on any all information.... If you wish to address a specific bug, please visit us on the weekly conference call so we can address them... We¹re getting close to time for rolling Release Candidate for 1.2 and we want to address as many of these as possible... Also, I¹m looking for some configuration documentation help. If you¹ve pulled git in the past few days you¹ll notice that in the module src directories there is now a conf directory, we need some help with making sure all the configuration options are documented and what their default settings are. The end goal is to get all the options documented in their default states. What skills do you need? The ability to read a little C, and the ability to use a text editor to edit/create configs... K

Re: [Freeswitch-dev] Busy trigger implementation in mod_skinny

Please read http://wiki.freeswitch.org/wiki/Mod_skinny/Development#TODO and keep in mind that some other features are closely related to Busy: - CFwdAll, CFwdBusy, CFwdNoAnswer: - DoNotDisturb: this also affects ringing - Ring policies: they will be easily implemented once the busy state is available - "Better behavior (when: other leg busy, ...) ", - maybe more Of course, you don't need to implement all those at once. > As far as I understand, this should be just after positive destination > matching method? There must be two things: - set call state to busy accordig to various conditions (the busy trigger) on the called phone (using switch_channel_hangup, around skinny_ring_lines or related) - handle this call state on the calling side (probably already done in mod_skinny.c line 784, function channel_on_hangup_callback) You can ask on @freeswitch-dev mailing list (or IRC), to code it the right way (the busy management should work from and to mod_sofia also). > Thanks for your response. Thanks for you proposal ;-) Once you have something working, put it in Jira. I will review and commit. -- Mathieu Parent

Fw: Usage of ODBC pooling
by Erjan Tylepov 27 Mar '12

27 Mar '12

Hi all! I guess, that mod_nibblebill's functions bill_event and get_balance lacks either mutex locking or connection pooling. Could someone check this out? What will happen if two or more calls (threads) get into those functions, i.e. there's a probability, that they'll use globals.master_odbc simultaniously? ----- Original Message ----- From: Erjan Tylepov [mailto:e.tylepov@btcom.kz] To: freeswitch-dev(a)lists.freeswitch.org Sent: Thu, 15 Mar 2012 09:24:21 +0000 Subject: Usage of ODBC pooling > Hi there! > > Is this sequence, which should be executed for every db access, is a right > way of ODBC connection pooling usage in FS: > switch_odbc_handle_new > switch_odbc_handle_connect > either > switch_odbc_handle_exec > switch_odbc_statement_handle_free > or > switch_odbc_handle_callback_exec > switch_odbc_handle_disconnect? > > Regards, > YT.

FreeSWITCH Wiki Update: Syntax Highlighting Now Available!
by Michael Collins 26 Mar '12

26 Mar '12

Hey all, Hat tip to David Knell for figuring out how to get the GeSHi syntax highlighting to work on wiki.freeswitch.org! If you'd like to have syntax highlighting on a snippet of code just do this: <source lang="{lang}"> ...code... </source> Languages include: c, perl, python, xml, lua, etc. Example: <source lang="xml"> <extension name="test ext"> <condition field="destination_number" expression="^(1234)$"> <action application="answer"/> <action application="log" data="INFO Thanks David!!"/> <action application="hangup"/> </condition> </extension> </source> I added the basic information to this page on the wiki: http://wiki.freeswitch.org/wiki/Documentation_Guidelines#Wiki_Markup If you would like a non-glamorous but useful task to do: feel free to edit each code sample you see to have the <source> tag with the appropriate language. Also, if there are any GeSHi warriors out there who could write a FreeSWITCH Log syntax highlighter module I'm sure that would be welcomed. :) Thanks again! -Michael

CentOS for ARM
by Michel Daggelinckx 25 Mar '12

25 Mar '12

Our favorite distro goes ARM. This gives a platform that feels like home and should have all our recepies work like a charm. Michel -------- Originele bericht -------- Onderwerp: [CentOS] CentOS for ARM Datum: Sun, 25 Mar 2012 15:17:20 +0100 Van: Gordan Bobic <gordan(a)redsleeve.org> Antwoord-naar: CentOS mailing list <centos(a)centos.org> Aan: centos-devel(a)centos.org, centos(a)centos.org Hi guys, I recently became aware that this is being worked on as of recently. A similar thing already exists, though. Those interested in an ARM port may also be interested in taking a look at RedSleeve Linux, which is an ARM port of the same upstream distribution as CentOS. You can look here for more info: http://www.redsleeve.org/about/ http://www.redsleeve.org/ In total 109 SRPMs had to be modified in order to get them to build and work on ARM. They are in SRPMS/changed directory on the RedSleeve mirror. (Note: About 5 of those 109 were changed in order to remove the upstream branding which isn't relevant to the CentOS effort as it is already taken care of. It is quite well known what those are.) I hope this is of interest to the CentOS ARM port efforts. Or, you could take RedSleeve for a spin, since that is already available. :) Gordan _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos
