FreeSWITCH

Since July, 2013, the W3C Object Real-Time Communications (ORTC) Community Group has been actively working on a next generation WebRTC API, called ORTC. Robin will discuss the latest updates of the ORTC API, the remaining challenge areas, and the implementation status of ORTC-lib. I will show the detailed event capabilities for ORTC-lib.Links:

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.

This week the verto communicator link to previewing the camera and microphone in the settings, the ability to play background video while recording inbound video, and a re-design of the banner code in mod_conference.

Join us Wednesdays at 12:00 CT for some more FreeSWITCH fun! This week we have Doug Waller from Flowroute! And, head over to freeswitch.com to learn more about FreeSWITCH support.

New features that were added:

• FS-8908 [verto_communicator] Link to preview camera and microphone under settings
• FS-8909 [core] Add feature to play background video while recording inbound video. This feature is suitable to provide some kind of feedback like an animation of a glowing record light etc.

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

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

Blake Priddy joins the ClueCon Weekly team to talk experiences deploying FreeSWITCH in rural public schools and some of the technical and political challenges he faced.

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

Dear FreeSWITCHers,

We would like to share this open letter with you to say thank-you for your support. You really came through and helped keep our developers fueled and functioning during our annual summit. With your donations we were able to provide lunches and dinners for our team while they worked hard to keep FreeSWITCH moving forward.

This meeting allowed us to coordinate some awesome plans for ClueCon 2016 and formulate exciting additions for the code base! Meetings like these are extremely beneficial to the team and allow in depth discussions to help work through some of the more difficult problems.  We also have some exciting news for our community coming down the pipeline! So, once again, thank-you so much for your support!

This week we had a minor improvement to the error response on hang up of a video call. And, for those of you Ubuntu fans out there, we have started a Ubuntu Packages GoFundMe to help get officially supported Ubuntu 14.x and 15.x packages! Please donate to support the cause! The developers work hard to create and maintain these packages and we need support from the community to make that happen.

New features that were added:

• FS-8847 [core] When a call ends sometimes the RTP stack complains of a bad poll. This is normal caused by shutting down the rtp on hangup. Add some code to catch the condition that is ok and still print the error otherwise.

The following bugs were squashed:

• FS-8838 [mod_rayo] Improve logging and error handling when executing API on output component. Attempt to make output component stop a little more robust and do a better job of detecting when output component completed because of hangup and preventing operations on output component when call has ended.
• FS-8839 [verto_communicator] Fixed screenshare not displaying in the proper conference when caller is transferred to another conference.
• FS-7132 [mod_verto] Fixed an issue with multiple websockets overwriting the jsock hash entry for a given sessionid causing a disconnection with the verto javascript application.
• FS-8806 [core] Change group_confirm_cancel_timeout to apply only to the legs that answer the call to prevent the remaining legs ringing indefinitely if the answered leg hangs up while executing the group confirm script.
• FS-8821 [core] Fixed switch_core_hash_insert_locked and switch_core_hash_insert_wrlock to make sure they check the status of the operation before returning a switch_status.
• FS-8811 [mod_local_stream] Fixed an intermittent segfault
