mod_skypopen, new HOWTO

21 Aug 2014

      Many users have discovered with dismay they can no more operate the old
Skype client used by mod_skypopen.

Starting first week of August 2014, Microsoft stopped operating the
authorization
servers for Linux Skype clients prior to version 4.3.37.

Skype 4.3.37 is the only Skype client version that works.
Those new Linux Skype clients require Pulseaudio.

New Skype clients and Portaudio use much more CPU on your machine.

With new Skype client, MAX 6 INSTANCES OF THE SAME SKYPEUSERNAME (see below)

Follow this page and use the automatic installer, you will be all set.

Please read it all.
===========================================================================
SHORT BLUEPRINT: STEPS NEEDED TO USE SKYPOPEN

   - Compile and install FreeSWITCH
   - Compile and install mod_skypopen
   - Install (on Linux) Xvfb and Pulseaudio
   - Configure Pulseaudio for low cpu usage
   - Download and install Skype client (on Linux, this is done by the
*INTERACTIVE
   INSTALLER*)
   - Configure Skype client (on Linux, this is done by the *INTERACTIVE
   INSTALLER*)
   - Install and edit mod_skypopen config file (on Linux, this is done by
   the *INTERACTIVE INSTALLER*)
   - Create a script to start the Skype clients with needed parameters (on
   Linux, this is done by the *INTERACTIVE INSTALLER*)
   - Start Skype clients using the script
   - Start FreeSWITCH
   - Load mod_skypopen in FreeSWITCH
   - Profit!

*NEW Interactive INSTALLER for LINUX*: using the provided script, you'll
end up with a complete and configured, ready for calls, installation of
Skypopen on FreeSWITCH!!! (see below)

Which Skype Client to use on Linux

Use the *dynamic* build of the *stable* Skype client (4.3.37), is the only
one that works

(the *interactive installer automatically download and install the correct
Skype client*, see below).

*Don't* use the package for your distro
 Supported Platforms and Distros

Skypopen runs well on Linux and Windows. Does *not work on Mac OSX*.

Most used Linux distro are:

   - Debian 7 64 bit server (wheezy)
   - CentOS 6.5.x 64 bit server(RHEL6)
   - Ubuntu SERVER LTS 64 bit (Trusty - 14.04)

Linux  Which packages are required to build mod_skypopen on Linux

You will need the libraries needed by Skype client and by the fake X
server.

*REALLY, you need all the packages below!*

You can cut and paste the follow:

In addition to the packages required to build and run FreeSWITCH, you will
need the following:

 # Dependencies for building mod_skypopen:
 yum install \
 libx11-devel

 # Infrastructure needed to run skype client:
 yum install \
 pulseaudio Xvfb xorg-x11-fonts* xz pulseaudio-utils

 # Dependencies of skype client:

 gtk2-engines.i686 PackageKit-gtk-module.i686

 Build procedure (all Linuxes) for FS and mod_skypopen

Note you must install the *hd sounds and music* packages, that includes
both 8khz and 16khz (skype works at 16 khz native), eg: from FreeSWITCH
source directory: "make hd-sounds-install && make hd-moh-install"

*After you finished to compile FreeSWITCH, in FreeSWITCH source directory
edit modules.conf and uncomment the mod_skypopen line*. Then, "make
install" again from the FreeSWITCH root directory (this will compile and
install just the mod_skypopen module).

make install #yes, again, this time will add mod_skypopen

  Pulseaudio Configuration  Debian 7

Configuration files:

edit /etc/default/pulseaudio
PULSEAUDIO_SYSTEM_START=1

edit /etc/pulse/system.pa # delete or comment out all file contents,
and add at the end:
load-module module-null-sink
load-module module-native-protocol-unix

edit /etc/init.d/pulseaudio
# delete --high-priority

edit /etc/pulse/daemon.conf
# add at the end of the file:
daemonize = yes
system-instance = yes
resample-method = trivial
flat-volumes = yes
default-sample-rate = 48000
default-sample-channels = 1
default-fragment-size-msec = 20

Add the user running the Skype clients to pulse-access group

adduser root pulse-access

 Ubuntu 14.04

Configuration files:

edit /etc/init/pulseaudio.conf
# uncomment "start on ..."

edit /etc/pulse/system.pa # delete or comment out all file contents,
and add at the end:
load-module module-null-sink
load-module module-native-protocol-unix

edit /etc/init.d/pulseaudio
# delete --high-priority

edit /etc/pulse/daemon.conf
# add at the end of the file:
daemonize = yes
system-instance = yes
resample-method = trivial
flat-volumes = yes
default-sample-rate = 48000
default-sample-channels = 1
default-fragment-size-msec = 20

Add the user running the Skype clients to pulse-access group

adduser root pulse-access

  CentOS 6.5

Configuration files:

edit /etc/init/pulseaudio.conf
# uncomment "start on ..."

edit /etc/pulse/system.pa # delete or comment out all file contents,
and add at the end:
load-module module-null-sink
load-module module-native-protocol-unix

edit /etc/pulse/daemon.conf
# add at the end of the file:
daemonize = yes
system-instance = yes
resample-method = trivial
flat-volumes = yes
default-sample-rate = 48000
default-sample-channels = 1
default-fragment-size-msec = 20

Add the user running the Skype clients to pulse-access group

usermod -G pulse-access -a root

Disable SELinux

edit /etc/sysconfig/selinux # disabled!

Start Pulseaudio, there is no /etc/init.d/pulseaudio, so you must start it
"by hand" (eg: from /etc/rc.local):

/usr/bin/pulseaudio --system=true --daemonize=true --log-level=info
--log-target=syslog

 Interactive Skype Client INSTALLER and CONFIGURATOR

Go to the "install" subdir of mod_skypopen sources, then execute the "
install.pl" script.

cd /usr/src/freeswitch/src/mod/endpoints/mod_skypopen/install
./install.pl

It will ask you questions and will let you review all the values you
entered before to do any real action.

Then it will download and install (where you told it) the correct Skype
client, and will create and install (where and how you told it) all the
needed configurations and startup scripts.

You'll end up with a complete and configured installation of mod_skypopen
for FreeSWITCH, ready for calls.

From 0 to Skype calls in 30 seconds !!!
 Skype 4.3.37 is the only Skype client version that works
Starting first week of August 2014, Microsoft stopped operating the
authorization servers for Skype clients prior to version 4.3.37. They
require Pulseaudio. Following this page and using the automatic installer
you will be all set, no problem.
 How to start the Skype clients, then start FreeSWITCH and load
mod_skypopen on Linux

First you start the Skype clients with the script created by the
interactive configurator, then you start FreeSWITCH, and load mod_skypopen
in it.

sh /usr/local/freeswitch/skypopen/skype-clients-startup-dir/start_skype_clients.sh
/usr/local/freeswitch/bin/freeswitch
load mod_skypopen

Yay!
 Problems in starting skype clients ?

Check you disabled both SELinux (on CentOS) or AppArmor (on Ubuntu)

Multiple concurrent incoming calls to the same Skype username

*Solutions based on "transfer" the call to another Skype username do not
work anymore with new Skype client*
 Running multiple instances (MAX 6) of the same Skype username on Linux,
for BOTH incoming and outbound calls

*The new Skype client limits the concurrent instances of the same username
to 6*

*MAX 6 INSTANCES PER SKYPENAME* (you can have many skypenames, each one
with a max of 6 concurring instances, eg: myskypenameA is used by 6
concurrent skype clients, myskypenameB is used by 6 concurrent skype
clients, myskypenameC is used by 6 concurrent skype clients, total 36
concurrent instances on your machine)

On Linux, you can run multiple instances of the same Skype username (eg:
multiple Skype clients that register with the Skype networks as the same
username, eg: 6 instances of the username "Bob"). On Windows, is not
possible.

Please use the *INTERACTIVE INSTALLER*, it will setup all (download and
install the correct Skype client, script to start the Skype clients, Skype
client configs, skypopen.conf.xml config file).

The trick is to launch the client instances with separate Xservers (as
always with multiple clients) AND separate directories for the Skype
client's database (eg: by default it resides in the ".Skype" directory in
the user's home).

You can find an example configuration file and launch scripts in
configs/multiple-instance-same-skype-username/ directory.
