In response to the thread " $500 bounty RTMP to conference room", try something like this: <action application="record_session" data="{modname=mod_av,vw=320,vh=240}rtmp://${ipOfDestination}:${portOfDestination}/${queryPathForDestination}"/>

quality/stability of freeswitch under docker
by Nathan Neulinger 15 Oct '20

15 Oct '20

I've got a production environment that's been running w/ a source build on ubuntu 16.04 for several years. I'm in the process of upgrading this to ubuntu 20, which also appears to be working fine. Setup is dual hosts with keepalived for failover, pointing to a separate 3-node mariadb based galera cluster. However, during this process I've been considering whether it would be a bit cleaner to move to a docker based deployment to have freeswitch inside the container use the more fully "supported" debian packages. Anyone have any thoughts on the general stability/performance/etc. of running FS under docker vs source build? Any differences? Main areas of concern I have are the network interactions, and I was thinking about using the 'host network' mode to address that. I'm looking at using https://github.com/signalwire/freeswitch/blob/master/docker/master/Dockerfi… modified to reference buster instead of jesse. (Can't see doing an updated deployment on 8 if 10 has production-ready packages.) Any feedback/experiences/etc. would be appreciated. -- Nathan ------------------------------------------------------------ Nathan Neulinger nneul(a)mst.edu Missouri S&T Information Technology (573) 341-6679 System Administrator - Architect (573) 612-1412 System and Desktop Infrastructure Team Manager

IVR UI/UX design
by Sam van Herwaarden 15 Oct '20

15 Oct '20

Hi all, My organization runs a number of IVR systems for information delivery, and one issue we often run into is that users find the interface a bit awkward or hard to navigate. We have experimented quite a bit internally with adjusting the structures of menus, ordering, phrasing etc. But we feel like there must be some knowledge/experience out there and that it shouldn't be necessary to rediscover most of this ourselves. Does anyone have recommendations for resources with info on best practices for IVR design? Or contacts in organizations/companies that have a lot of experience with this? Kind regards, Sam

action application="capture_video"
by David P 15 Oct '20

15 Oct '20

I just came across this intriguing snippet: <action application="capture_video" data="#transcode{vcodec=h264,acodec=mpga}:std{access=file,mux=mp4,dst=/tmp/1.mp4}"/> I can't find any documentation for capture_video; does it allow setting the sample rate? Can it be used more than once in a dialplan to create an mp4 at the conference rate and a wav at a higher rate?

Freeswitch skipping silence packets in recording file
by Shahnawaj Khan 14 Oct '20

14 Oct '20

Hello All,, I am working on freeswitch 1.10.2 and using record_session to record the media of the calls. I am running a scenario where we have silence on both ends of the call for a few minutes. Assuming We have the call talk time of 10 mins and the call contains 1 minutes of silence. The recording file size is around 9 minutes and 30 seconds i.e. it contains 30 seconds of silence but also skipped for about 30 sec. I haven't configured the "silence_hits" value for the record_session. I am unable to find the default value of silence_hit associated with record_session or it may be due to some other reason. Thanks & Regards, Shahnawaz

moh music on hold
by Bote Man 14 Oct '20

14 Oct '20

This is very interesting! Giovanni, do you mean that FS reads once the target of the “hold_music” variable? Or specifically “local_stream://moh” as an argument to local_stream? I’ll update the wiki with this useful info. Thanks. --- John Boteler BnC Group U.S.A.

I’m simply playing back a file. I wonder if this is cpu bounding. I guess I can test this by doing echo instead. to eliminate cpu load from reading/decoding file, use moh (read just one time, then broadcast samples to all calls, no cpu, I believe less than echo in case of many concurrent calls) -giovanni I also added another profile, since I read on a thread it might help (also read that’s not true), but that’s not it. All of my metal boxes work just fine at ~3000 channels, so I’m thinking it’s related somehow to the underlying VM. Thanks again.

Were you using the call centre module in your test? If so, I'd suggest moving it to an external RDBMS such as PGSQL (could be running on the same VM). FS is multi-threaded but there are certain processes which FS creates a dedicated child process for (one thread) such as SQLite (one process per database). If you can find out which FS process is using 100% CPU on one thread then you should be able to identify the bottleneck.

Freeswitch CPU consumption on AWS EC2
by ziv＠ip-com.co.il 13 Oct '20

13 Oct '20

Hi, We run FreeSWITCH on Amazon AWS EC2, using the c5.xlarge machine size, meaning 4 CPUs with hyper-threading, sums up to 8 vCpu. In time of high-traffic, the system is reaching 100% CPU at about 400 concurrent sessions, which is typically 200 calls (2 sessions per call). RTP is sent as G-711. SIP signaling is this test is UDP (no TCP or other protocols). These numbers are after reducing the log level and moving the core-dsn to memory. The dialplan in this test is very simple. ulimit values are as recommended in FreeSWITCH documentation. On thread level, we see many threads that consume <1.5% CPU. Several threads consume more, apparently the signaling. Question: Do these numbers make sense? We expected to see much more traffic before the CPU is congested. Are there simple tricks to reduce the CPU usage (as we did with changing the log level) Is there a way to analyze the CPU consumption so we can try and improve? Thanks
