Windows MSI installers
by Peter Johnson 08 Oct '15

08 Oct '15

Hi there I'm looking to obtain FreeSWITCH for Windows, which I normally download from http://files.freeswitch.org/windows/installer/ - are these really the latest generated from Git HEAD? They are dated in January 2015 and don't seem to be even 1.6? Thanks in advance for any advice Peter

Conference vs codec sample rate and CPU
by Oleg Stolyar 07 Oct '15

07 Oct '15

Hi guys, I have a bunch of conferences on my FS. Users are either G.711/8000 or G.722/8000. Conference sample rate is set to 8000. When I switched some users to OPUS instead, the CPU consumption jumped 3-4 times even though the conference rate is still 8000. Is this expected? I was hoping to be able to save some CPU by setting the conference sample rate to auto (so it only used high-quality sampling for users that can support it) but it seems it won't work. Any ideas?

Low-Level Conference API
by Johannes Singler 07 Oct '15

07 Oct '15

mod_conference offers audio/video conferencing services. The usual way to start/join a conference seems to be to dial in to a special number. However, we would like to use mod_conference with custom signaling, so basically just the mixing part. For that, we would need some low-level API for conferences, with functionality like 1. Add a participant with a given offer SDP: return an answer SDP, start mixing it in and start the RTP stream to the new participant. 2. Remove a participant, stop mixing him, and stop the RTP stream to the respective device. Can this be achieved by using mod_event_socket, or would we have to implement a proper FreeSWITCH module for such things? -- Johannes Singler Software Engineer Qnective

Windows Startup Problem
by Steve Matzura 07 Oct '15

07 Oct '15

Installed last week's 1.6 build and cannot start the CLI. When I run the console program, absolutely nothing happens--no error, no response at all. I have Visual Studio 2012 installed, and when I tried replacing the C++ library with the downloadable redistributable one, Windows informed me my 2012 version is newer, which it most certainly is. I am also aware others have had this problem, as detailed on https://freeswitch.org/confluence/display/FREESWITCH/Windows. The reporter was directed to this list, so now here am I, hoping the solution was posted and someone will please repost it. Thanks in advance.

Re: [Freeswitch-users] Freeswitch and twilio

if you have a deep look at inbound gateway it is for receiving calls from Twilio as you can see below, this line informing freeswitch where to route inkling call. <param name="extension" value="1000"/> > > > From: Michael Nielsen <mic.niel84(a)gmail.com> > Date: October 2, 2015 at 11:24:51 PM GMT+3 > To: FreeSWITCH Users Help <freeswitch-users(a)lists.freeswitch.org> > Subject: Re: [Freeswitch-users] Freeswitch and twilio > > > Outbound works fine. > > Without having the inbound gateway calls are still routed to my FS to my public context from Twilio. > Adding the twilio-inbound doesn't seem to change anything...? > > > > On Friday, October 2, 2015, Brian West <brian(a)freeswitch.org <mailto:brian@freeswitch.org>> wrote: > Well you'd send outbound calls out the outbound and the inbound one is just to register with twilio so they know where to send your inbound calls.

I know their names indicate inbound and outbound calling, but how can Freeswitch tell the difference between them. Especially how can Freeswitch now to use twilio-inbound for incoming calls from twilio and not just twilit-outbound as the only difference is register-proxy and expire-seconds between the two? > > Make sense? > > _________________________________________________________________________ > Professional FreeSWITCH Consulting Services: > consulting(a)freeswitch.org <javascript:_e(%7B%7D,'cvml','consulting(a)freeswitch.org');> > http://www.freeswitchsolutions.com <http://www.freeswitchsolutions.com/> > > Official FreeSWITCH Sites > http://www.freeswitch.org <http://www.freeswitch.org/> > http://confluence.freeswitch.org <http://confluence.freeswitch.org/> > http://www.cluecon.com <http://www.cluecon.com/> > > FreeSWITCH-users mailing list > FreeSWITCH-users(a)lists.freeswitch.org <javascript:_e(%7B%7D,'cvml','FreeSWITCH-users(a)lists.freeswitch.org');> > http://lists.freeswitch.org/mailman/listinfo/freeswitch-users <http://lists.freeswitch.org/mailman/listinfo/freeswitch-users> > UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users <http://lists.freeswitch.org/mailman/options/freeswitch-users> > http://www.freeswitch.org <http://www.freeswitch.org/> > > > > -- > Brian West > brian(a)freeswitch.org <javascript:_e(%7B%7D,'cvml','brian(a)freeswitch.org');> > > Twitter: @FreeSWITCH , @briankwest > http://www.freeswitchbook.com <http://www.freeswitchbook.com/> > http://www.freeswitchcookbook.com <http://www.freeswitchcookbook.com/> > Got Bugs?

Why only 3 frame sizes in mod_opus?
by Michel Aoun 07 Oct '15

07 Oct '15

I think that only 3 frame sizes (10ms, 20ms and 40ms) are implemented in mod_opus? Is there a reason for not adding the entire list of 2.5, 5, 10, 20, 40, and 60 ms (https://tools.ietf.org/html/rfc6716#section-2.1.4)? Thanks

FS priority
by Bote Man 07 Oct '15

07 Oct '15

I'm trying to set the priority on a new FreeSWITCH installation built from master on Debian 8 running on bare metal. It is currently running at "very low" priority according to Resource Monitor in the GUI and 'top' reports FS is running at priority = -2 (that's negative two) and nice = 19 So with the way FreeSWITCH is now launched by systemd is it considered a service or a user application that is simply run in the background? This affects how systemd treats its control groups and priority and how I will go about troubleshooting this. Thanks. Bote

Opus PLC issue - can this be a bug?
by Thomas 07 Oct '15

07 Oct '15

Hello list, on a connection with an unfortunate amount of packet loss, I'm getting a lot of these: mod_opus.c:289 FEC in CELT_ONLY mode ?! ... with the occasional ... mod_opus.c:801 Decoder Error: corrupted stream fs:4080 plc:false! switch_core_io.c:622 Codec RAW Signed Linear (16 bit) decoder error! [9] ... and ... switch_rtp.c:875 Invalid STUN/ICE packet received 493 bytes That's accompanied by robotic distortion. This sounds more like FS is receiving total junk rather than missing packets, but surely there must be checksums preventing errors inside these packets? Can this really be a bug in FS, or do I need an exorcist for that internet connection? :) Cheers! Thomas P.S.: Last nights master

Cannot get verto video conf demo working
by Tao Zhang 06 Oct '15

06 Oct '15

Hi, I am new to FreeSwitch, WebRTC and etc.. so please bear with me. :-) I tried to set up the latest FreeSwitch Video Conf demo on my server and could not get it working. I can call extension 3500 and enter the conf, but I only see a black area with no video and no sound. On the other hand, if I access the official video conf demo page https://conference.freeswitch.org/verto/#page-main from FreeSwitch, it works fine. I have been trying to figure out what is wrong with my FS setup. I cannot see any obvious errors from the FS server log and from the JS console. But from the chrome://webrtc-internals/, two ssrc_xxxx_send stats show bytes sent are zero. Also two ssrc_xxxx_recv stats show bytes received also zero. So it seems there is some problem related to the peer connection between the client and the FS server? I also noticed another difference in webrtc-internals outputs between my server setup and the official working one. For my set up, Channel-video-1 shows: >>>>>>>>>>>>>>>>>>>>>>>>>>>>> Channel-video-1 Statistics Channel-video-1timestamp10/6/2015, 5:48:56 PMgoogComponent1 localCertificateId googCertificate_29:3D:26:CC:D2:E0:1D:35:1E:0B:66:EA:B4:08:B7:FC:EE:FC:7B:0A:76:C5:6F:AE:B7:BD:D4:7B:73:10:E6:F7 selectedCandidatePairIdConn-video-1-0 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> For the official setup, Channel-video-1 shows: >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Statistics Channel-video-1timestamp10/6/2015, 5:37:53 PM selectedCandidatePairIdConn-video-1-0googComponent1dtlsCipher TLS_ECDHE_RSA_WITH_AES_256_CBC_SHAlocalCertificateId googCertificate_56:D3:CE:E1:0C:81:05:2A:FB:E7:17:3F:34:FB:21:F3:DD:F8:67:99:65:2D:D6:41:57:76:64:3A:ED:00:96:01 remoteCertificateId googCertificate_EB:11:4A:1F:D3:CE:18:2B:16:CE:6A:F4:71:5D:F6:A6:9E:22:63:8C srtpCipherAES_CM_128_HMAC_SHA1_80 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> I guess the dtls-srtp connection is not set up properly, since remoteCert and other fields are missing in the webrtc-internals dump for my setup.
