Lua event hook limitations
by Eugene Prokopiev 28 Jul '20

28 Jul '20

Hi, What is allowed do in lua event hook and what is not? I tried to catch UA register event and send call to registered UA, so I did: <configuration name="lua.conf"> <settings> <hook event="CUSTOM" subclass="sofia::register" script="reg2call.lua"/> </settings> </configuration> local name = event:getHeader("username") local realm = event:getHeader("realm") local user = string.format("%s@%s", name, realm) freeswitch.consoleLog("notice", string.format("REGISTRATION FROM USER %s\n", user)) local session = freeswitch.Session(string.format("user/%s", user)) session:setAutoHangup(false) session:transfer("000", "XML", "webrtc") freeswitch.consoleLog("notice", string.format("USER %s TRANSFER\n", user)) But in many cases I receiving CUSTOM sofia::register event with some delay (up to 2 mins) Why and how it can be fixed? -- WBR, Eugene Prokopiev

Is there a way to tell FreeSWITCH to just pass VP8? Right now its decoding and scaling and encoding my video from webrtc to sip. ><> nathan stratton

mod_portaudio on Raspberry Pi currently broken?
by Lesley Pervis 27 Jul '20

27 Jul '20

I compiled mod_portaudio for rpi (arm11) in January. No problem. I compiled it again this week. Problem. Logs show it can't find any devices. So I copy the mod_portaudio.so and mod_portaudio_la from January to the newly compiled installation, and voila, devices found. I did a git diff in src/mod/endpoints/mod_portaudio, and there have been a couple of changes in the mod_portaudio.c file, but nothing that would explain this. Mod-portaudio source doesn't seem to have changed, just the way it's build. (Still version 1899, V19-devel.) The newer mod_portaudio.la shows different dependences, and the new mod_portaudio.so is much smaller. I think mod_portaudio is currently broken for raspberry pi and likely other platforms too. Anyone have any insight?

Banning IP address that attempt registration via IP
by Don Hawkins 27 Jul '20

27 Jul '20

Hey everyone! So I have quite a few "security" features installed on the server, including custom IP banning methods using IP Tables, (fail2ban caused too many issues). All endpoints on our system register via a domain, I'm looking for suggestions on how to block IP addresses that attempt to register with the IP address only. In other words, every time the warning below is received I'd like to ban that particular IP or at least add it to a list somewhere. WARNING: "You must define a domain called 'XXX.XXX.XX.XXX' in your directory and add a user with the id" I'm thinking of a custom script that scans the logs (which logs?) Any advice is appreciated. Thanks!

Can a module like mod_lua continually monitor the audio and video of a call leg? I can't find any examples.

How to prevent video scaling
by Nathan Stratton 25 Jul '20

25 Jul '20

in vpx.conf.xml I have rc-resize-allowed, rc-scaled-width, and rc-scaled-height all set to 0, but FreeSWITCH is still downscaling my video.

CPU availability?
by David Villasmil 25 Jul '20

25 Jul '20

Hello all, Let's assume i have a 28 CPU (56 cores) with 64gb RAM. I'm load-testing that box with something like this: SIPp->--\ /----> FS1 ---->FS SIPp->--/ \----> FS2 SIPp is simply sending calls with rtp to FS. FS just forward the calls to FS1 and FS2 based on some very simple decision. FS1 and FS2 simply answer and execute echo. At ~2000 channels FS fails to reply to some SIP messages, basically calls are timing out, answer ratio goes down. BUT CPU never goes over 45% on the FS and memory is ample. I don't see packe drops on the interface. FS is running in a docker. I'm wondering whether FS would use all of the available CPU or am I hitting some other limit somewhere. Any insight is welcomed!

Freeswitch fault tolerant setup
by John Tuxies 24 Jul '20

24 Jul '20

I have heard that it is possible to have 2 or more Freeswitch servers with their own IP and share a Virtual IP. All users users will know only the virtual IP and in case of a failure of one server, the call will be retrieved from the next available server. I would like to ask if there are any detailed guide on how to set it up, so i could have a working lab to experiment with it.
