[Freeswitch-dev] Stereo support?
by Xijing Dai 14 Dec '12

14 Dec '12

hey guys, Have anyone try to implement stereo support in freeswitch to streaming the music? I tried, but only 1 channel is hardcoded inside freeswitch code everywhere, i can't make it work properly, just wonder if any1 tried before? Can we share some experiences? What I tried: File IO needs to support 2 channels shout module needs to support 2 channels L16 needs to support 2 channels it should auto convert between 1 channel codec and 2 channel codec for encoding/decoding. The problems I had are: * some random RTP sending error. (using PCMA codec, before encode, i did convert audio from stereo into mono). * music voice becomes noise. ( I tried to use MPG123_FORCE_STEREO to convert 1 channel music to 2 channel music). Cheers Xijing

[Freeswitch-dev] How to find out what changed in a release
by Craig Ayliffe 11 Dec '12

11 Dec '12

Hi, I am looking at the ChangeLog in the tarball for the latest release 1.2.5.3, and it doesn't have an entry. Plus I also noticed the last two entries (1.2.5.2 and 1.2.5.1) in the ChangeLog also just say 'Maintenance release/bug fixes'. So how would I find out what has changed, i.e. which bugs have been fixed in each release? Regards, -- Craig

Greetings! We are glad to report that the FreeSWITCH team has tagged version 1.2.5.3. You can download the tarball here<http://files.freeswitch.org/freeswitch-1.2.5.3.tar.bz2>. Anyone using 1.2.5.x should update as soon as possible. We appreciate all those who have helped us with testing and tracking down some sneaky and pernicious little bugs. On last week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_05>we spent some time talking about the XML parser and some of its pre-processor directives. We discussed specifically how you can use the "exec" command to execute a shell script in the middle of XML processing. We also discussed a few tricks on how to look at the source code when you need to learn about some FreeSWITCH functionality that otherwise is not documented. This week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_12>subject is still pending, so stay tuned! One other item I'd like to mention is that we've had several reports of FreeSWITCH success stories. We will be providing more information about those in upcoming stories on our Web site. We've got people using FreeSWITCH in various situations as well as software developers who've added support for FreeSWITCH to their offerings. The FreeSWITCH ecosystem continues to grow and flourish! Thank you all for being a part of it. Take care and have a great week! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

[Freeswitch-dev] About the display problem during calling
by sparklezou 05 Dec '12

05 Dec '12

Hi All, I facing a strange problem. Before, when calling Internal number, the name and number will both be displayed on the caller phone. When connected, only the name will display on the phone. At called phone, display the name and number. Seems fine. But yesterday afternoon, when calling Internal number, only the number is displayed on the caller phone. When connected, display "Outbound Call" on the caller phone. At the called phone, everthing is the same. Display both the name and number. I think, mabybe something configured wrong. So I try to restore back the configuration. seems the same. I have to re-install the last release stable 1.2.5.1 version on another server. total fresh setting. But found the same problem. I checked the sip info. The "Outbound Call" is in the 200 SDP message. the called is set to ""Remote-Part-ID: "Outbound Call" <sip: 1234(a)a.b.c.d>; ....... " Not the correct called name. Is there anything wrong? Please help me. Thanks! 2012-11-30 sparklezou

[Freeswitch-dev] Conference CDRs via http
by Mariusz Czulada 04 Dec '12

04 Dec '12

Hi all, I was thinking about sending CDRs via HTTP in a same or similar way mod_xml_cdr does. I consider implementing this (unless someone else is working on it) but first wanted to discuss with you the best approach. A. All in mod_conference This would require to copy many fragments of code from mod_xml_cdr into mod_conference. Also same configuration parameters used in xml_cdr must be processed and used for sending data. The advantage for this solution is that everything related to this mechanism is included in this module. Drawback: if something in mod_xml_cdr requires fixing or extending, probably the same changes should by applied in related parts of mod_conference. B. mod_conference builds, mod_xml_cdr sends data For this solution I'll give more details. 1. New event type should be added (like SWITCH_EVENT_CDR) 2. When a module (in this case: mod_conference) wants to store CDR via HTTP it must fire an event of that type and: - "Event-Subclass" set (like "conference") - Only common headers are needed, plus... - "Content-Type" and "Content-Length" must be set - CDR data must be build as XML in a module and added as an event content. 3. mod_xml_cdr will listen to this event type. 4. For each event subclass which mod_xml_cdr must must react, configuration file will contain a set of params same as for generic channel CDRs. 5. If subclass matches configuration, mod_xml_cdr reads data from event content and sends them according to configuration. Changes in mod_conference: - one new parameter for each profile (like "cdr-via-event=yes|no") - if "yes" then xml must be build even if "cdr-log-dir" is unset - if "yes", then an event must be fired as described above Changes in mod_xml_cdr: - extra parameters from configuration to be parsed (like '<settings subclass="conference">....</settings>') - bind to SWITCH_EVENT_CDR - if 'Event-Subclass' matches configuration, a content of the event will be sent via HTTP (probably most of 'my_on_report' routine bellow 'try to post it to the web server' comment will be reused) A [small] drawback is that it makes an indirect module dependency, but we already have such situations (like mod_shout needed to record a conference in mp3). Advantages are: - one can create an external tool for handling this type of event (to store it directly in db or send it with other protocols) - this mechanism can be easily reused in other modules if needed; maybe in mod_callcenter, maybe in other components. No further changes in mod_xml_cdr should be needed. What is unknown to me is a maximum size of event content. Conference CDR XMLs can be quite big - will it be a problem to send it this way? I think the second solution is better and more universal but I'd like to hear your opinions about this case. Regards, Mariusz

Happy December to everyone! Last week was painful for many of us as we were dealing with a sustained DDoS attack on most of our infrastructure. Kudos to the guys for working through it. It seems the worst is over and we can get back to the business at hand: doing FreeSWITCH stuff. :) In spite of the drama last week we did have a conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2012_11_28>and we released 1.2.5.2! We discussed mostly the details of the DDoS we experienced and how the community can assist in the future so that we can mitigate the effects of such an occurrence. With the community's help we will be more resistant to the effects of any future attacks. We appreciate the outpouring of support we received from everyone. This week <http://wiki.freeswitch.org/wiki/FS_weekly_2012_12_05> we will go back to discussing FreeSWITCH. We are still finalizing future guests so this week we'll do another installment of tips and tricks from the FreeSWITCH community. Among other things I will be showing how Chris Rienzo (IRC: crienzo) and I used the source this weekend to figure out what the XML preprocessor can do and get the wiki updated. I'll then show a simple example of the always-present-but-previously- undocumented command can do. As an added bonus we'll have an update on the ClueCon <http://www.cluecon.com> 2012 videos! Thanks and have a great week. -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE
