[Freeswitch-dev] Server having Freeswitch and two Sangoma cards and can't handle full capacity
by Sambit Jaysingh 12 Sep '14

12 Sep '14

We are having two (Sangoma) Voice Cards, one with 8-ports and other with 16-ports. I have integrated ESL library with java in INBOUND MODE and making outbound calls. The issue what we are facing are 1. When I use all 720 channels or more than 450 channels, we see the events processed by ESL is very slow and we are not getting the events properly from ESL after placing the calls, even after so many minutes, so we have to forcefully close the connection. 2. And I see error mod_event_socket.c:375 Lost 502 events! And the java app also crashes with error ESL connection timeout. 3. And I see segmentation_fault in Freeswitch and big dump file is written and which would crash the system, because of high CPU\IO. But if we reduce the channels say, 450 we don't see any issue at all. What could be the reason for this issue. Appreciate any Help... -- Regards Sambit +91-9916211211

[Freeswitch-dev] Implementing preferred channel selection in freetdm using sangoma isdn ?
by Matteo 01 Sep '14

01 Sep '14

Hi, the following applies to ftmod_sangoma_isdn. Scenario: some pri isdn switches does not like exclusive channel selection, but needs the setup message to carry a preferred channel selection ie. Adding this in freetdm (in setup message) and making it configurable is easy and an example patch is attached. BUT! If the remote switch changes the channel, we need to "move" the current freetdm channel to the one specified in the provisional response or setup ack. According to q.931 is wrong to allocate a b channel before having confirmed the right one to use, but right now freetdm allocates it immediately. (maybe is worth changing that?) So, I'm trying to understand all the stuff between freetdm and ftmod_sangoma_isdn in order to modify it and make the preferred b channel selection working. Any hint ? Which is the best way to "swap" a freetdm channel or move to another? Is something the stack already allows or needs some major modifications? mat

by takashi higashi 31 Jul '14

Hey guys, I sent e-mail to freeswitch developer about how to get rtp packet with ffmpeg. and I asked to him below question. How can I get rtp packet with ffmpeg? I want to trancoding real time rtp packet to motion jpeg and transfer node.js. and then, he answered like this, The following works for me: ffmpeg -re -f lavfi -i aevalsrc="sin(400*2*PI*t)" -ar 8000 -f mulaw -f rtp rtp : // 127.0.0.1:6666 ffmpeg -i pcmu.sdp -acodec copy /tmp/a.wav or ffmpeg -i bingbing.mp4 -an -vcodec h264 -filter:v scale=1280:720 -f rtp rtp : // 127.0.0.1:6668 looks like pcmu is not a valid codec for mp4, so I use aac ffmpeg -i pcmu-264.sdp -acodec libfaac -vcodec copy /tmp/a.mp4 So I asked about what is 6666 ports? How can I get rtp real-time audio and video ports? but I couldn't get answer... Somebody help me, how to get real-time rtp audio and video ports? please.

[Freeswitch-dev] Registration through extension
by Fernando Flórez 30 Jul '14

30 Jul '14

Hello, I would love to have some guidance on how to achieve user registration through an extension. Phones will be placed on a restricted context by default, if a user calls an specific extension they will be prompted to enter their extension and password and if successful, the phone will start working under that extension on a different (not restricted) context. Multiple phone registration should also be possible. Thank you!

[Freeswitch-dev] WebRTC and Freeswitch 1.5 using IPv6
by Tom Parrott 28 Jul '14

28 Jul '14

Hi, I am experimenting with WebRTC and am failing quite dismally - mainly due to lack of documentation. I realise this is an emerging technology and the standards are moving, but presumably it does work in some scenarios and it would be great if a working setup could be documented. Anyway, I think I might have found a bug, but have no way to tell because I've never been able to get WebRTC working with Freeswitch. Here's my setup so far: * FreeSWITCH Version 1.5.14b+git~20140725T212415Z~c411f8c7a9~32bit (git c411f8c 2014-07-25 21:24:15Z 32bit) * IPv6 addresses - due to shortage of global IPv4 address, I am forced to use IPv6 * SIPJS - http://sipjs.com/ * Firefox 31/Fedora 20 * Apache 2.4.9/Mod_SSL * Startcom SSL cert (which I have configured with Apache fine) What I am able to do: If I setup the internal IPv4 profile with ws-binding, I can use SIPJS to register and can successfully see a user registered in Freeswitch from the browser. I can then use SIPJS to make a call, and my desk phone rings, however I get no media (UDP packets are being sent but presumably neither side can decode it). I also see these errors in the fs_cli debug output though: * **2014-07-27 13:04:12.108836 [ERR] switch_core_cert.c:210 FP FILE ERR!** **2014-07-27 13:04:12.108836 [ERR] switch_core_cert.c:210 FP FILE ERR!** **2014-07-27 13:04:12.148104 [ERR] switch_rtp.c:2975 audio DTLS cert err [5]* But I can find no proper documentation on what is required for DTLS or where to put the cert files. Next up I tried IPv6 in the internal-ipv6 profile: <param name="tls-cert-dir" value="/etc/freeswitch/certs"/> <param name="wss-binding" value=":7443"/> I concatenated the cert, key and chain certs together into /etc/freeswitch/certs/wss.pem and can successfully connect using WSS and SIPJS. The problem however is that although I can see a register, Freeswitch then kills the registration connection a couple of seconds later. It is also showing the registration as using WSS-NAT, how can that be possible on IPv6? How can I turn off NAT detection on the IPv6 profile? Any guidance would be very much appreciated and I will post my setup to my blog and the Freeswitch wiki if I can get it working, to help people in the future. Thanks Tom
