[Freeswitch-dev] Friday Free For All Topic: GSoC 2013
by Michael Collins 28 Feb '13

28 Feb '13

Hey all! We thought that maybe a good idea for a discussion topic for tomorrow's Friday Free For All (F3A) would be potential projects that FreeSWITCH/OSTAG could sponsor as a mentoring organization. Please bring your fresh ideas and we'll talk about them! Thanks! -- Michael S Collins Twitter: @mercutioviz http://www.FreeSWITCH.org http://www.ClueCon.com http://www.OSTAG.org

[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 26 Feb '13

26 Feb '13

Greetings! First item in the news today is a happy report from long-time FreeSWITCH user Henry Gavin. Henry runs a company in the U.K. called SureVoIP<http://www.surevoip.co.uk>. He is pleased to report that "thanks to FreeSWITCH and FusionPBX" his company is once again a finalist for the annual ITSPA awards<http://www.surevoip.co.uk/blog/2013/02/25/surevoip-and-the-surevoip-api-fin…>. Congrats to Henry for leveraging FreeSWITCH in a successful business endeavor. Another annual event is the Google Summer of Code<http://www.google-melange.com/gsoc/homepage/google/gsoc2013>(GSoC). FreeSWITCH will once again apply as a mentoring organization. Please start thinking of project ideas that we can include in our organization's application. Applications will be submitted starting March 18 and no later than March 29. Ken Rice and I will be coordinating this process. Stay tuned for more details. On last week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2013_02_20>we did a nice tour of the CudaTel <http://www.cudatel.com> Communication Server. In the coming weeks we will have more presentations for GUI front-ends that community members have built. On this week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2013_02_27>we will have Ken Rice give us an update on his new project: SwitchPi <http://switchpi.org>. If you like DIY projects then you'll appreciate what Ken has done with integrating the Raspberry Pi with FreeSWITCH and some other items to create something new. We look forward to seeing it in action. Don't forget about the FreeSWITCH HA discussion on Tuesday evening at 8PM EST. Last week's discussion was very fruitful. Eliot Gable gave us all a lot of information about the different approaches that he can take for building mod_ha_cluster <http://wiki.freeswitch.org/wiki/Mod_ha_cluster>. We look forward to his report on the potential of using OpenMPI<http://www.open-mpi.org/>. For those who can't make it to the HA discussion please join weekly conference call on Wednesday where we will have a brief recap of the HA call. In ClueCon <http://www.cluecon.com>news we have uploaded two new videos: * What's new in sipXecs 4.6 <http://youtu.be/mz14UqXRQDU> - Douglas Hubler * Challenges and Opportunities in Open Source VoIP<http://youtu.be/QnDYE-DfjgU>- Travis Cross Stay tuned for more ClueCon 2012 videos and ClueCon 2013 announcements. Have a great week and we look forward to talking to you on Wednesday. -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

[Freeswitch-dev] Q: anyone built fS (head) on Mountain Lion?
by Lawrence Conroy 25 Feb '13

25 Feb '13

Hi there, quick question: as per subject, has anyone succeeded in building fS on Mac OS X mountain lion with portaudio. At this end it seems to barf trying to make universal binaries (i.e., with ppc code). That isn't going to fly as ppc64 is no longer supported with Mountain Lion's SDK, AFAICT. Yes, on a clean update to ML I did have to pull in and install (m4), autoconf and automake and libtool first. all the best from a puzzled Lawrence

[Freeswitch-dev] on_init hook and outgoing channels
by Alex Massover 24 Feb '13

24 Feb '13

Hello, We have services that manage calls via ESL and want to write a custom authorization and billing module. The idea is to catch any call received by FreeSwitch before service gets control on ESL for incoming call and on_init hook works for us. But for outgoing channels (created by 'route' or 'originate' commands over ESL) on_init hook doesn't work. Well the channel hits the hook but already after outgoing INVITE being sent, although channel state goes from CS_NEW->CS_INIT->CS_ROUTING correctly. And I want to authorize the channel before it goes out. Is that a normal behavior or I completely miss something? Is there other way to block an outgoing channel after it's created but before it goes out from a custom module? -- Best Regards, Alex Massover

Can anyone guide me how to rectify the same. -- With Regards, Anindo Mazumdar,

[Freeswitch-dev] reload logfile.conf on reloadxml or sighup?
by Beeton, Carolyn (Carolyn) 22 Feb '13

22 Feb '13

I would like to be able to trigger Freeswitch to reload the logfile.conf file (to pick up changes in log level on the fly). I know this can be done by changing levels on the console, but since my application uses configuration files to persist the changes, I would prefer to keep all configuration data in the files. The "reloadxml" command triggers FS to reload some but not all of the config files. Could it be enhanced to reload logfile.conf? Or would it make sense to reload the logfile.conf file on receipt of sig_hup? Or have I missed another way to accomplish this? If there's any interest, I will create a jira and offer a patch. Thanks, Carolyn

[Freeswitch-dev] simultaneous interpretation conference system
by Jamie McClelland 21 Feb '13

21 Feb '13

Hi freeswitch devs, This is my first post to the list so I want to start by thanking you for the great work you have done on Freeswitch. And, sorry for the long post! I have specific questions at the bottom... I'm looking for advice on how to build a simultaneous intrepration conference call system. The way we'd like it to work: The system is required to handle two languages, but the ability to handle more than two languages would be an added bonus. For the purposes of this description, I'm giving the example of spanish and english. The conference call would have spanish-only, english-only, and bi-lingual speakers. In addition, one or more interpreters would be on the call. Bi-lingual speakers would participate in the call like it was a normal conference call. They would hear speakers in the original english or spanish, and would have the option of speaking either english or spanish based on their preferences. The english-only and spanish-only speakers would press 1 to hear a live intrepretation of the call. When spanish is spoken on the call, an english intrepretaton would be heard. When English is spoken, a spanish interpretation would be heard. This would only affect what they hear - they could still speak into the main conference. Participants would press 0 to return to hearing the main conference call. The interpreters would press 2 to enter interpretation mode. During this mode their voice is not heard on the main conference, instead it's only heard by people who have pressed 1 to hear the interpretation. When english is spoken, the intrepret to spanish and vice-versa. They could press 0 to return to the normal conference mode. Ideas on how to implement: First - has anyone implemented anything like this already? Based on the wiki docs, I think the conference relate function would be ideally suited for ensuring people who press 1 only heard the audio from people who have press 2 and for reversing the effect when 0 is pressed. Any ideas on a better way? The next problem is how to capture the digits pressed by conference call participants. I *think* this could be done by running a process that listens for freeswitch events. However, I'm not sure how much information is sent with the event. It would need to pass the conference id, the user id, and the digit they pressed. Is that information sent by the event handler? Or, is there a more elegant way to capture key-presses by conference participants? Thanks in advance for any light you can shed on this topic, jamie -- Jamie McClelland May First/People Link Growing networks to build a just world http://www.mayfirst.org https://support.mayfirst.org OpenPGP Key: http://current.workingdirectory.net/pages/identity/

[Freeswitch-dev] uuid_record Question
by Kevin Snow 20 Feb '13

20 Feb '13

I'm using the uuid_record function to record the read side of a sofia session. Used in conjunction with switch_ivr_play_file() and an echo server I can place a call, play a sound file and record the echo. Easy enough and works with a problem of occasional little dropouts. I recorded my daughter saying "Ooma" and duplicated it a bunch of times as a test sound file. This makes a nice repetitive sample to look at. I've included an image of the recorded audio (from echo) as displayed in Audacity (hopefully this makes it through). In the 5th and 7th "Ooma" there is a dropout. When I listen to the live echo it sounds fine, but listening to the recording I can hear the ticks. This does not happen every time, but enough to be a bother. Has run into this? Ideas on how to stop it? Thanks Kevin [cid:96A0D21F-8B75-475F-98F1-710EF4EE7231]
