News from Industry

Enhanced. Fixing. Solving. Enterprise grade. Improving. Completing.

I’ve been seeing this too much lately.

Companies decide to market their product as a way to “fix” WebRTC. The gall.

I understand where this comes from. Marketing is a lot about FUD. How to put fear in your potential customer until the only thing left for him to do is buy.

If you look closely, though, none of them really “fixes” WebRTC. The only thing they are doing is using WebRTC in a way that may fit you as a customer.

An example?

Companies who “fix” WebRTC by adding signalling to it. Or adding authorization. Or having it connect to PSTN.

This isn’t about “fixing”. This is about supporting a specific scenario or feature in a product – not even related to WebRTC itself.

Others “fix” WebRTC by having it work on IE (forcing a plugin on the user or using Flash). Again, less about WebRTC, and more about the use case.

And you know what? WebRTC doesn’t offer notifications either – I am sure you can go ahead and “fix” WebRTC by adding push notifications to your app on top of WebRTC!

WebRTC is a very powerful building block, but that’s about all it is – a building block. You’ll need to add additional building blocks to create a solution with it, so no – you aren’t fixing it – you are just implementing your use case with it.

Please.

Stop fixing WebRTC. It isn’t broken.

Just focus on solving a real world problem for a real customer and be done with it.

Earlier this month Fippo published a post analyzing Slack’s new WebRTC implementation. He did not have direct access or a team account to do a thorough deep dive – not to mention he is supposed to be taking some off this month. That left many with some open questions? Is there more to the TURN network? […]

Looking forward to meeting many of you at Kamailio World 2016!

The biggest news this week is the edition of a Raspberry Pi installation script adding by Ken Rice. Grab yourself a Raspberry Pi and go try it out!

Join us Wednesdays at 12:00 CT for some more FreeSWITCH fun! This week we are talking about Raspberry Pi and the Internet of Things! And, head over to freeswitch.com to learn more about FreeSWITCH support.

New features that were added:

• FS-8932 [mod_managed] Add in process load in-process plugins
• FS-8933 [Debian] Basic FreeSWITCH from source installer that works on Raspbian and Debian. Also installs VertoCommunicator and LetsEncrypt SSL Certs. LetsEncrypt requires the machine to have a public IP and DNS for the FDQN functioning properly in public DNS
• FS-8870 [core] Add human-readable call quality statistics logs on call hangup
• FS-7800 [verto communicator] Added support for calling extra screens with same extension as the original and place the parameter conferenceCanvasID with the desired canvas id into the call parameters in the same place bandwidth preferences are added

Improvements in build system, cross platform support, and packaging:

• FS-8948 [Debian] Handle non-existent configuration in Debian postinst causing failure to copy vanilla configuration on installation
• FS-8841 [Debian] Prevent hanging by pushing events to another queue to be processed in a different sofia thread.
• FS-8942 [build] Pass compiler to libvpx configure to account for environments without gcc
• FS-8952 [Windows] Fixed an issue with unreachable code preventing build and simplify conditions

The following bugs were squashed:

• FS-8938 [mod_conference] Clear res_id when setting the same res_id to another member
• FS-8951 [mod_conference] Video lockup in conference due to race condition
• FS-8957 [mod_conference] Fix for video image blipping on personal canvas mode when 1 participant is watching video on hold
• FS-8943 [configure] Fixed misspellings in two comments
• FS-8950 [mod_skinny] Fixed a few memory leaks
• FS-8946 [mod_xml_cdr] Fixed a segfault on call after loading with no config file or event bind failure causing the module load to fail
• FS-8937 [mod_easyroute] Handle a segfault when using bad customer query or on query error
• FS-8855 [core] Fixed the calculation of variance of tone’s frequency estimator to prevent flawed audio
• FS-8928 [core] Flag a binding error when using EventConsumer::bind with invalid event name instead of blindly using custom
• FS-8168 [core] Use copy image functions from libyuv instead of our home rolled versions as the libyuv versions have optimizations
• FS-8406 [mod_rtmp] Add options to scale down cavas size, fps, and bandwidth
• FS-7915 [mod_sofia] Parse and store multiple path fields
• FS-8663 [mod_sofia] Added saftey checks for ;fs_path= command
• FS-8945 [verto_communicator] Don’t show preview_settings window during a video conference call or you will lose conference video stream until you refresh the page

They really truly are.

Whenever someone whines to me that WebRTC isn’t a standard yet so it isn’t ready it makes me laugh. Who the hell cares about such a thing anymore?

The standard is whoever’s got the clout and strength in the market. Ask any marketer – would they want to be able to interact with the carrier’s standardized, federated (and almost non-existent) RCS client to send a message – or would they rather be able to interact with WhatsApp users. The answer, for countries where WhatsApp is popular will be WhatsApp. Marketers don’t care about the standard. The users don’t care about the standard. And most developers don’t care either – as long as the interface is adequately documented.

Enter WebRTC.

No. The IETF hasn’t gone through the motions and finalized the spec yet.

Yes. It might change.

No. I couldn’t care less.

You see, there are already billions of users available to me via WebRTC. There’s source code I can take, compile and run anywhere I want. There’s a vibrant ecosystem of developers and vendors ready to assist. There’s a large and growing number of companies and use cases that make use of WebRTC.

Who am I to say that WebRTC doesn’t exist because someone didn’t put their “standard” stamp on it?

For the last 3 years I’ve been using WebRTC almost daily to communicate with others using various services. I didn’t think for once that this isn’t working because there’s no standard.

Whenever companies band together to create a standard, I begin to question their motive. These days, it usually comes from a point of weakness – a place where there is one (or more) vendors who are strong in a domain and the only way the smaller kids can have a go at it is by specifying a standard to rally all small players to fight the dominant force.

Whenever you see a standard being announced – ask who isn’t there – that’s the one with the power.

In the case of codecs, the MPEG-LA asserts its power and dominance over H.264 and H.265/HEVC for video codecs. Which is why the aomedia was created and announced – to find an alternative codec and win the market back.

The examples are countless.

In the domain of real time communications, everyone were using H.323 or SIP. Then Skype came out, ignoring standards altogether. The industry tried its best to explain that Skype isn’t federated. There’s no standard there. To no avail. So companies (the same ones) tried connecting to Skype, to offer that as part of their service.

The same is happening today with WhatsApp and other social networks. They are so big, that they are the standard.

WebRTC is making the same distinction. It is taking away the hegemony on VoIP from VoIP vendors and putting the weight of this industry on the browser vendors. And now, these vendors are complaining that WebRTC isn’t interoperable. Doesn’t fit their needs. They don’t understand that they are neither in control here nor influencers. They lost control over that part of technology.

This isn’t to say that WebRTC won’t stabilize or get standardized – it is just that it doesn’t matter when it comes to adoption.

Standards? They are for the losers to run after to make sure they get to play the game. The winners don’t really need them.

Planning on introducing WebRTC to your existing service? Schedule your free strategy session with me now.

With no major issues reported, Kamailio is on a good track for releasing stable v4.4.0. Next week a lot of people prepare for Easter, therefore I propose to do the release on Wednesday, March 30, 2016. If new things pop up, the exact date can be adjusted a bit before or after the current proposal.Any new discovered issue should be reported to bug trucker:

• https://github.com/kamailio/kamailio/issues

Help to complete the upgrade guide would be very appreciated:

• https://www.kamailio.org/wiki/install/upgrade/stable-to-devel

A draft list of what is new in 4.4 is already available at:

• https://www.kamailio.org/wiki/features/new-in-4.4.x

Enjoy upcoming v4.4.0 and thank you for flying Kamailio!

An install script for Raspbian and Debian 8 is now available.

This script makes it easy to deploy FreeSWITCH from source on your Raspberry Pi running Raspbian or on a standard machine running Debian Jessie.

Along with installing FreeSWITCH, Verto Communicator and LetsEncrypt are installed and configured. (Note: For LetsEncrypt to be configured you must have a valid public IP and hostname in DNS pointed at the machine.)

To use this script:

wget -O FreeSWITCH-debian-raspbian-installer.sh "https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/scripts/FreeSWITCH-debian-raspbian-installer.sh?raw"
chmod +x ./FreeSWITCH-debian-raspbian-installer.sh
./FreeSWITCH-debian-raspbian-installer.sh

Once the script completes, you will have FreeSWITCH installed to /usr/local/freeswitch, Verto Communicator in /var/www/html/vc, and if you set up the public IP and DNS name, LetsEncrypt SSL certificates installed.

Most of the accepted speakers at Kamailio World 2016 are now listed on the event website. There are many new speakers, several involved in the early stage of SER-Kamailio development, ready to reveal insides about project evolution. See more details at:

Had to take this one out of my system.

Just in time for Enterprise Connect, Dave Michels decided to write a post to attract readers. The title? WebRTC is a distraction. It is hard to pin point what’s wrong with the arguments in this one, but most of them are just lacking in knowledge or understanding of this market and how it operates, which is sad – especially coming from Dave who I value very much.

The 4 main reasons why it is a distraction for Dave?

1. Limited support
2. Mobile is what really matters
3. Why bother?
4. WebRTC is dangerous

Let’s try to dismantle each of these so called arguments one by one. Shall we?

#1 – Limited Support

WebRTC today runs on Chrome and Firefox. Microsoft went for ORTC (=WebRTC) and is now “considering” WebRTC as well.

Apple isn’t there, but frankly – I almost never hear complains about Safari not having WebRTC. For some reason, Mac uses have been trained to use Chrome when needed. Furthermore, there’s work been done at Apple about WebRTC, if you care about rumors.

Add to that the fact that no other solution runs on a browser. No other. None. Zilch. They are all getting thrown out from browsers who are stopping support for plugins, Java and probably Flash in the future. And what else have this amount of support anyway?

Now, you can use WebRTC as a desktop app, using a plugin, through Java – or in whatever other manner people use their comms today – so that limited support is wider than any other alternative to date.

#Doesn’t work for you? Don’t use it. But don’t complain that others are using it and are happy about it.

#2 – Mobile is what really matters

To whom?

And while at it, using WebRTC inside an app makes a lot of sense. You shouldn’t care about the technology – just your customers. If they want apps, give them apps. Wrap WebRTC and be done with it.

There’s no other serious media engine for mobile that can be considered – the price point for it will be too prohibitive as well as the investment made.

Mobile is what really matters, which is why Facebook Messenger uses WebRTC. In both mobile and desktop. And is probably larger in deployment, users, minutes, seconds and engagement than anything else the unified communications market has to show for its huge success in its 10+ years of existence.

You know what? I am tired of waiting for unified communications to happen. It is time we take matters into our own hands (with WebRTC) instead of waiting for these large stale companies to move at a reasonable pace and come up with a workable solution.

#3 – Why bother?

Dave says Google no longer cares or invests in WebRTC. I’d say this can’t be further away from the truth.

Google are heavily invested in WebRTC today, based on the number of new features and changes they bring with every new version of Chrome (which happens every 6-8 weeks as opposed to 12-18 months of the slow vendors Dave asks us to put our trust in).

The pace of change for WebRTC is staggering. Nothing comes close to it.

In the span of a year, we’ve seen the echo canceler getting replaced in WebRTC, VP9 introduced, H.264 is underway, ORTC related APIs getting added and that’s just what I can remember off the top of my head (and really took place in the last couple of months only).

Will Google continue at these breakneck speed? Who knows? For now, I’ll take what I am given – especially for free.

#4 – WebRTC is dangerous

Not sure where to start here.

With Unified Communications and its current cadre of vendors, the issues raised by Dave (things you don’t understand and control coupled with hard to patch and upgrade) are a lot more dangerous.

Do you know when your PBX was upgraded last for that critical security issue it had? Do you even know if it was upgraded at all? What about the router you have at home? This FUD about security in WebRTC wreaks of misundersanding of the technology.

We are living in a world where we move everything to the cloud and our mobile devices. In such a world, security needs to be taken seriously. Not by introducing stupid proprietary solutions that are hard to manage or maintain, but rather by introducing cloud based solutions that can upgrade and update automatically. Ones where security is taken into account from the ground up and not as a bolt on feature to show the buyer.

WebRTC has all that and more, so if you think WebRTC is dangerous – sure it is. To anyone who is trying to compete against the companies using it. In the long run, resistance is futile.

The truth of it

Google doesn’t care about the unified communication market when it comes to WebRTC.

They just couldn’t care less if this does headaches to Cisco or Polycom or anyone else in this market. The way vendors are bitching about WebRTC shows how they view VoIP and UC as their own, as if they are entitled to what goes on there and as if someone needs to think about their business models and legacy deployments so they don’t get hurt.

Get over it.

WebRTC is a huge distraction to those who aren’t built to embrace it. They are going to fade away. Just a matter of time. And Dave – you won’t need to wait much longer for it to happen.

The GIT branch 4.4 was created, it will host the Kamailio release series 4.4.x. To get this branch from GIT, you can use:git clone https://github.com/kamailio/kamailio.git kamailio
cd kamailio
git checkout -b 4.4 origin/4.4Notes about installing Kamailio from this branch are available at:

• https://www.kamailio.org/wiki/install/4.4.x/git

Hopefully in about two weeks or so the full release of 4.4.0 will be out.From now on, any corresponding fix has to be pushed first to master branch and then cherry-picked to branch 4.4. No new features can get in branch 4.4. Enhancements to documentation or helping tools are still allowed.

Installing, Compiling and running FreeSWITCH on the Pi 2

The long and awaited for… FreeSWITCH 1.7 running on a Raspberry Pi 2 guide.

We’ll be using the latest (at the time of this writing) Raspbian image 2015-11-21-raspbian-jessie.img on a Raspberry Pi 2.  Thanks to the awesome FreeSWITCH team at https://freeswitch.org/ especially Brian West, Ken Rice, and William King for all of their efforts with the FreeSWITCH project and helping me to get this working.

 

Raspbian running on your Pi

You’ll first need to have the Raspbian image running on your Raspberry Pi.
 

Installing Dependencies

In order to compile FreeSWITCH and it’s modules, you need to install some dependencies.

Update your Pi packages

sudo apt-get update && sudo apt-get upgrade

The following packages were installed and I was able to successfully compile FreeSWITCH with the default modules in the modules.conf file, that were selected when I cloned the git master branch.  My default modules.conf of enabled modules is located at the bottom of this page for reference.  Note, If you enable/uncomment other modules in the modules.conf that gets created after running ./bootstrap.sh -j command below, you may require some additional dependencies.

sudo apt-get install autoconf automake devscripts gawk libjpeg-dev libncurses5-dev libtool-bin python-dev libtiff5-dev \
libperl-dev libgdbm-dev libdb-dev gettext libssl-dev libcurl4-openssl-dev libpcre3-dev libspeex-dev libspeexdsp-dev \
libsqlite3-dev libedit-dev libldns-dev libpq-dev libsndfile-dev libopus-dev liblua5.1-0-dev

These packages are required, but were already installed on my Raspbian (here for reference)

sudo apt-get install g++ git-core make pkg-config

These packages are required, but Installed by other packages. (here for reference)

sudo apt-get install libjpeg62-turbo-dev libtool

 

Clone git FreeSWITCH Repo

You can clone to any directory, but we’ll use the directory /usr/local/src and need to make it r/w to our user ($USER is a system variable, which will = the current user, pi in our case)

sudo chown $USER /usr/local/src

change to that directory

cd /usr/local/src

Clone the git repo (master branch)

git clone https://freeswitch.org/stash/scm/fs/freeswitch.git

 

Compile FreeSWITCH on the Raspberry Pi 2

Goto the FreeSWITCH source directory

cd /usr/local/src/freeswitch/

Confirm master branch

git checkout master

Returned: Already on ‘master’ Your branch is up-to-date with ‘origin/master’.

Build config files

./bootstrap.sh -j

Now we’re at the point where you can enable/disable custom modules to compile along with the FreeSWITCH framework.  In this build, I left all the modules in modules.conf default (My enabled modules in modules.conf file is located below for reference).  You can always compile additional modules at a later point when they are needed.  I recommend leaving the modules.conf file alone if this is your first time compiling, you can read more about it below in the section Enabling additional Modules in modules.conf

Run configure

./configure -C

Make (use jobs flag -j set to 3) in attempt to speed things up (this took ~30 minutes)

make -j3

Success!

Install FreeSWITCH

sudo make install

The FreeSWITCH binary is now located in the /usr/local/freeswitch/bin directory.

 

Compile sounds for FreeSWITCH

make cd-sounds-install cd-moh-install -j3

Goto FreeSWITCH bin directory

cd /usr/local/freeswitch/bin

Start FreeSWITCH

*It is advisable to skip this step if you are configuring FreeSWITCH to start up automatically at boot, as it creates files that are needed during run-time and it will fail when you use the init script/systemd to run it automatically. 

./freeswitch

check to see if it is running (just to make sure it compiled ok to this point)

ps aux | grep "freeswitch"

Auto Run FreeSWITCH at boot

We’ll add FreeSWITCH as a user, change a few permission, copy the startup script and test the auto start of Freeswitch.

Create FreeSWITCH user, add password and set permissions

cd /usr/local/ sudo adduser --quiet --gecos "FreeSWITCH Voice Platform" --ingroup daemon freeswitch sudo chmod -R ug=rwx,o= /usr/local/freeswitch/ sudo chmod -R u=rwx,g=rx /usr/local/freeswitch/bin/* sudo chown -R freeswitch:daemon /usr/local/freeswitch

 

Create link from source build to expected locations

sudo ln -s /usr/local/freeswitch/bin/freeswitch /usr/bin/freeswitch sudo ln -s /usr/local/freeswitch/bin/fs_cli /usr/bin/fs_cli sudo mkdir /etc/freeswitch sudo ln -s /usr/local/freeswitch/conf/freeswitch.xml /etc/freeswitch/freeswitch.xml sudo chmod ug=rwx,o= /etc/freeswitch sudo chown freeswitch:daemon /etc/freeswitch sudo mkdir /var/lib/freeswitch sudo chmod -R ug=rwx,o= /var/lib/freeswitch sudo chown freeswitch:daemon /var/lib/freeswitch sudo cp /usr/local/src/freeswitch/debian/freeswitch-sysvinit.freeswitch.default /etc/default/freeswitch sudo chmod ug=rw,o= /etc/default/freeswitch sudo chown freeswitch:daemon /etc/default/freeswitch

Create working log directory

sudo mkdir /var/log/freeswitch sudo chmod -R ug=rwx,o= /var/log/freeswitch sudo chown freeswitch:daemon /var/log/freeswitch

Copy the start-up script to /etc/init.d/ directory and change permissions

sudo cp /usr/local/src/freeswitch/debian/freeswitch-sysvinit.freeswitch.init  /etc/init.d/freeswitch sudo chmod u=rwx,g=rx,o= /etc/init.d/freeswitch sudo chown freeswitch:daemon /etc/init.d/freeswitch sudo update-rc.d freeswitch defaults

FreeSWITCH will now auto start when the Raspberry Pi boots up

 

Reboot to confirm everything is working

sudo reboot

Check the status of FreeSWITCH

sudo /etc/init.d/freeswitch status

Manually start FreeSWITCH (for reference)

sudo /etc/init.d/freeswitch start

You may also want to confirm FreeSWITCH is listening on port 5060 (for troubleshooting)

netstat -ln

 

Register to Extension 1000

FreeSWITCH has a few default extensions.  As a simple test to see if FreeSWITCH is working, we’ll register a sip client to extension 1000, with the default password is 1234.

Change to user FreeSWITCH for editing of files or logging into fs_cli, since we have changed permissions of the directories in the above steps.

su freeswitch

Log into FreeSWITCH command line to assist in troubleshooting (type /exit to exit the FreeSWITCH command line)

fs_cli

Using your favorite SIP client on the same network as the FreeSWITCH server, register with extension 1000

• SIP Proxy/Server = <raspberry-pi-ip-address>
• SIP Port = 5060
• User ID/Name = 1000
• Password/Authentication = 1234

While you are logged into the fs_cli, turn on sip trace debug

// sofia global siptrace on

Then from your SIP client, attempt to register, viewing the SIP trace can greatly assist in troubleshooting.

Once you are registered, try to call some test extensions

• 9198 = tetris music
• 9197 = mw tone
• 9196 = echo test
• 5000 = Default IVR

 

9198 was called from a sip client

Who do you go to with your WebRTC needs?

That moment you realized you selected the wrong vendor

There are now over 20 vendors out there offering WebRTC APIs in the cloud.

20.

How the hell do you decide which one to pick for your service?

This question was rather “simple” to answer, but it is getting harder.

Two months ago, Facebook decided to shutdown Parse. This is something that should not be taken lightly.

In 2013, Facebook acquired Parse. Parse was a MBaaS(mobile backend as a service platform). If you want to build a mobile app, you’ll be needing some backend in high probability – a place to store account information, maybe sync data between users, etc. MBaaS does exactly that, and in this domain, Parse was one of the bigger platforms. They had around 60,000 applications on their platform at the time of acquisition – not something to take lightly.

Facebook didn’t acquire Parse for its great technology but rather for its developer ecosystem – for its popularity. In the two years since, Facebook invested more in the platform – just so it can close it.

In the context of communication API platforms with WebRTC capabilities, what we’ve seen so far are two kinds of acquisitions:

 

1. Acquiring a technology – Snapchat acquiring AddLive, Requestec getting acquired by Blackboard are such examples. So is Crocodile RCS acqisition by Acision and then Acision wrapped into Xuar
2. Acquiring a developer ecosystem – TokBox’s acquisition by Telefonica and the recent Cisco acquisition of Tropo

Will Cisco decide in a year or two to shutter down Tropo if it doesn’t bring the traction it wants or if it serves its purpose of getting enterprises to adopt Cisco Spark?

Would Telefonica stop investing in TokBox? Highly unlikely after 3 years, but who knows? I wouldn’t have bet on Facebook shedding Parse.

The thing about Parse is that Facebook didn’t even spun it off again – or sold it. It just closed the service. More akin to how Snapchat treated its own acquisition of AddLive.

Kin Lane explains nicely the false expectations people had from Facebook and Parse:

There is no basis for believing a platform or API will ALWAYS be there, no matter what you are promised. Companies go out of business, get acquired, and in this fast paced tech climate, companies are always looking to deliver the latest product, and features. Everything in the space points to disruption, change, and evolution, where the hell did we get the idea these services shouldn’t go away?

What can we deduce?

1. Platforms with large ecosystems aren’t impervious to being taken off market. TokBox may get shuttered. Twilio might get acquired
2. In the build vs buy decision of WebRTC, using a platform doesn’t mean write once and forget. You may need to update your code, switch vendors, etc. – be ready for it

–

As I start working on another update for my Choosing a WebRTC API Platform report, I will take the time to research the reasons for vendors selecting the less popular API platforms – what makes them take that plunge. If you are such a vendor – contact me.

Until this new update gets released (April-May timeframe), there’s a $700 USD discount on the report (which includes a 1-year update period).

This week we had some fun new updates to mod_avmd and began the process of moving libvpx into tree. This is a big change and should be carefully noted. There were too many issues associated with maintaining and updating it so the developers decided to instead link to a static version in tree.

Join us Wednesdays at 12:00 CT for some more FreeSWITCH fun! And, head over to freeswitch.com to learn more about FreeSWITCH support.

New features that were added:

• FS-8852 [mod_avmd] Now we use predefined table length instead of hardcoded computation in stop condition of for loop
• FS-8854 [mod_avmd] Now all members of buffer are initialized in INIT_CIRC_BUFFER macro
• FS-8867 [mod_vpx][core] Build using in tree libvpx, vpx no longer optional and does not use system libvpx due to issues with having to update it, frequently conflicting with system libraries, now we link to the static in tree version instead. Also, mod_vpx is now a core module instead of a loadable module, so mod_vpx.so will no longer be built
• FS-8876 [core] Add CPU affinity to each Video thread in a round robin fashion.
• FS-8878 [mod_amr] Make AMR NB transcode in octet-align mode (when compiled with HAVE_AMR)

The following bugs were squashed:

• FS-8856 [mod_callcenter] Updating a member fails because the agent_dispatch_thread removed the member just before it tried to update it.
• FS-8842 [verto] Fixed an issue where calls created using the originate command lose audio when left on hold for 45 seconds
• FS-8877 [verto] Fixed an issue caused by Chrome Canary removing some audio mandatory constraints that break Verto
• FS-8862 [core] Auto adjust on passthru
• FS-8871 [configuration] Fixed encoding “&” and “<” symbols in vanilla configuration
• FS-8879 [mod_sofia] Fixed SIP UPDATE and attended transfer for ipv6
• FS-8864 [core][mod_av] Improve video file playback

Digital Voice Teleconferencing overt the ARPAnet 1978

This week we had the addition of CPU affinity to each video thread in a round robin fashion and a logo image and parameters were added to mod_local_stream.

Join us Wednesdays at 12:00 CT for some more FreeSWITCH fun! And, head over to freeswitch.com to learn more about FreeSWITCH support.

New features that were added:

• FS-8876 [core] Add CPU affinity to each video thread in a round robin fashion.
• FS-8903 [mod_local_stream] Add a logo image and some parameters to control its behavior

The following bugs were squashed:

• FS-8884 [build] Add –disable-libyuv and –disable-libvpx configure arguments to disable building these libraries on FreeBSD and smartos
• FS-8891 [RTP] Fix for T38 fax failing between 2 freeswitch boxes with high cpu usage
• FS-8354 [mod_conference] Fix for G722 audio issues
• FS-8811 [core] Fixed an intermittent crash
• FS-8851 [core] Fix for codec for recording negotiated before call answered
• FS-8904 [core] Fix memory leak in img_write_text
• FS-8905 [core] Fixed for a heap buffer overflow detected by ASAN in the img patch/img overlay and it may show up as a rare segfault when using video with banners
• FS-8864 [core] Set video ready on first push to avoid catch 22 on some video files
