[Freeswitch-dev] FreeSWITCH Weekly News and Notes
by Michael Collins 15 Apr '13

15 Apr '13

Greetings! Happy tax day to those in the USA - we hope all is well with your business. Speaking of business, I thought I would relay the interesting news<http://www.cnbc.com/id/100637184>about Dish Network making a bid for Sprint. Many here in North America will be keeping a close eye on this one. Whether or not this is just a big mess<http://www.zdnet.com/softbank-sprint-clearwire-dish-figuring-out-this-merge…>or an opportunity for Sprint to become a "real" competitor to AT&T and Verizon remains to be seen. Regardless of the outcome, most of us here are hoping for a healthier Sprint so that we can avoid another duopoly. On last week's conference call<http://wiki.freeswitch.org/wiki/FS_weekly_2013_04_10>we decided to have a preliminary discussion so that we can prepare for this week <http://wiki.freeswitch.org/wiki/FS_weekly_2013_04_17>. Dave Kompel will be showing us how to build rapidly FreeSWITCH applications in MS Visual Studio 2012 and have those run under mod_managed<http://wiki.freeswitch.org/wiki/Mod_managed>. Be sure to consult this document<http://download.drknetworking.com/MeetingPreparation.pdf>so that you can get all the prerequisites installed in time for our call on Wednesday. In other news I would like to let everyone know that I spoke with Kashif Kahn over at Vestec <http://www.vestec.com>. We are gearing up for the automatic speech recognition application building contest. The winners will be announced at ClueCon 2013 <http://www.cluecon.com>. The official contest page will be posted on the ClueCon website shortly. Stay tuned for more information and be ready to start building your ASR applications! The ClueCon 2013 call for speakers recently went out and we've had a number of submissions already. We look forwarding to hearing more talk ideas, so please send those in right away. In the meantime ClueCon registration<http://www.cluecon.com/register/>is now open so be sure to get signed up, and don't forget to book your room at the Hyatt Chicago Magnificent Mile <http://www.cluecon.com/hotels/>hotel for only $169 per night. Have a great week! -- Michael S Collins ClueCon Team http://www.cluecon.com 877-7-4ACLUE

[Freeswitch-dev] Portaudio AEC take 2
by João Mesquita 15 Apr '13

15 Apr '13

Guys, I've been looking at an AEC solution to integrate on portaudio for the softphones to take advantage of it and it seems like WebRTC has one that could be used. I am not by any means an expert on the matter so before I start hacking things, I would like to ask your opinion. First of all, licensing... Is this license compatible? http://www.webrtc.org/license-rights/license If the license is compatible, where would be the best place to implement it? I would definitely need some pointers.. I found out that Blink is using it on PJMEDIA as this patch ( http://sipsimpleclient.org/projects/sipsimpleclient/repository/entry/patche…) shows. PJMedia already has an interface for noise supression and AEC so I guess it was "easy" to implement there. We would implement it as a media bug or on the portaudio module itself? Also, if anyone knows if this will bring good results, would be great! AEC that just works is something that is really wanted on a softphone... João Mesquita

[Freeswitch-dev] Sound Not Ok(Choppy Sound) after 250 ports
by Subhash 12 Apr '13

12 Apr '13

Hi, I ran the load test, raising the port count slowly (every 5 to 10 minutes or so) to 100, 150, 200, 250, 275 and 300 ports. There were no audio problems until I reached 275 ports. After probably 10 minutes at 275 ports, audio problems started, and after that they were consistent. Of course I can’t guarantee that there were no audio problems at lower port counts - if the problem only occurred intermittently I might not have caught it or I might not have waited long enough. Once the audio problems started, I slowly lowered the number of ports back to 250 ports. The audio problems disappeared after about 2 1/2 minutes at 250 ports. I then increased the number of ports back to 275 ports. Thanks, Subhash.

I see the dialplan execution is started but when playback execution is started is stops with hanging up my call. ( I have tried to pre-answer but...) I need something like " your_io_routines.outgoing_channel is called create a new session (with switch_core_session_request()) parse outbound_profile->destination_number to get called number qualify the session, attached channel and attached private data The channel is currently in CS_NEW Change channel state to CS_INIT Make the phone ring (and call switch_channel_mark_ring_ready()) your_state_handler.on_init is called Change channel state to CS_ROUTING your_state_handler.on_routing is called What to do here? The call is answered switch_channel_mark_answered(channel) " the info from Authoring_Freeswitch_Modules but with more details In my case: I have no calling of your_io_routines.outgoing_channel I do the codec staff in on_init function On_Routing I do the pre-answer On_Receiving I try to start rtp session I can not understand am I doing it right or not ?

Hello All, It is spring time (almost) again and as most of the things I need to reproduce or simply develop other kind of endpoint. The purpose: 1.I need other kind of signaling, a protocol which is not supported by FS 2.The need is the call to enter into the dialplan and execute it (FS to execute the dialplan a call from other signalization point is received) What I have done till now: I started from http://wiki.freeswitch.org/wiki/Authoring_Freeswitch_Modules#Before_You_Beg…... I have used mod_sofia and mod_skypopen as reference as result I am (the call is) into the dialplan now (using switch_core_session_execute_exten) but I can not deal properly with channel state callbacks and no RTP data is flowing/traveling/sending. I have been given some hints to check-out rtp.c but now I think I need more info about creating channels and dealing with their states. Then I will need to deal with the RTP data So if anyone have some clues and wants to share...I will be very glad
