教程 Siptosis and Asterisk

ckleea

There are currently 2 ways to integrate skype with asterisk. The end result is to allow in and out call from other skype users to your skype account and even sip to skype (skype to sip/voip)

1. buy skype for asterisk from digium
pro: simple native support from big company; with support
cons: expensive, one channel costs US$66 (http://store.digium.com/productview.php?product_code=1SFA0001); not every asterisk platform support, in particular embedded asterisk. Therefore, IP01 cannot work with skype for asterisk

2. buy siptosis for asterisk from MHSpot.com http://www.mhspot.com/sts/siptosis_skype_trunk_howto.html
pro: inexpensive US$4.99 for siptosis, you can even get the free version to make it work
cons: require a delicate skype terminal i.e. either a PC running windows and skype or using skype for linux; knowledge of linux and software installation in linux.

What is the SipToSis Skype Gateway?
SipToSis (Sip to Skype integration software) is Java software that allows you to make and receive Skype calls from your SIP/VOIP telephone adapter, SIP IP phone or Asterisk/SIP PBX. You can also make and receive SIP calls from Skype. It let's you integrate Skype into your SIP VOIP phone system. Basically a Skype/SIP Bridge/Gateway/Proxy/Adapter/Converter. It has a codec converter to convert SIP RTP audio to compatible Skype PCM audio and Skype PCM audio to SIP RTP audio. It performs SIP signaling and Skype call handling to connect with your SIP adapter, Asterisk Server, SIP PBX or SIP VOIP provider.

Installation

1. Basic asterisk on linux installation and skype client installation

http://www.mhspot.com/sts/sts_install_centos.html
Here is some info for setting up Linux. I don't get into PBX or ATA details here.
Modify username and folders as needed.
Most instructions are for CentOS, some also apply to other distributions.

Install CentOS 5.4 x64
If you don't choose a GUI option you will have to deal with any missing packages and start x yourself.
Create a user called stsuser
I disabled the firewall for this setup example.

update first
yum update

login as stsuser
mkdir downloads

Install Skype
Download Skype - static version 2.1.0.81 to /home/stsuser/downloads
su (use sudo for Ubuntu)
cd /opt
tar jxvf /home/stsuser/downloads/skype_static-2.1.0.81.tar.bz2
ln -s skype_static-2.1.0.81 skype
ln -s /opt/skype /usr/share/skype
ln -s /opt/skype/skype /usr/bin/skype

On a CentOS Server some additional packages are needed:
yum install libXv
yum install libXScrnSaver
yum groupinstall "X Window System"
yum install alsa-lib

On a Server twm will be used during the configuration process so some changes are needed to make it work:
vi /etc/X11/twm/system.twmrc - add RandomPlacement above NoGrabServer line.
cp /etc/X11/twm/system.twmrc /home/stsuser/.twmrc
chown stsuser:stsuser /home/stsuser/.twmrc

exit

Ubuntu 64 bit distros need 32 bit libraries (file not found error)
Install getlibs-all.deb package from here
cd /opt/skype_static-2.1.0.81
sudo getlibs skype

Setup snd-dummy - required if no sound hardware
su (or sudo)
/sbin/modprobe snd-dummy
gedit (or vi) /etc/rc.local
add /sbin/modprobe snd-dummy before exit 0:
exit

Test that skype works on it's own.
cd /home/stsuser
For a Server, first startx
skype &

Install Sun/Oracle's Java - Do NOT use openjdk
Ubuntu: sudo apt-get install sun-java6-jre
CentOS and Ubuntu can use following procedure:
Download file: jre-6u18-linux-x64.bin to /home/stsuser/downloads from Java (Linux JRE x64 version.)
su - (Don't miss the minus, use sudo on Ubuntu)
cd /opt
/bin/sh /home/stsuser/downloads/jre-6u18-linux-x64.bin

Method 1:
alternatives --install /usr/bin/java java /opt/jre1.6.0_18/bin/java 2
alternatives --config java
select correct java install if incorrect.

Method 2:
ln -s /opt/jre1.6.0_18/bin/java /usr/bin/java

java -version
confirm correct version.
exit

Install Xvfb
su
CentOS: yum install Xvfb
Ubuntu: sudo apt-get install Xvfb
exit

Add stsuser to audio group - Needed for automatic bootup.
su
usermod -a -G audio stsuser
exit

Install SipToSis
Download SipToSis to /home/stsuser/downloads
mkdir /home/stsuser/siptosis
cd /home/stsuser/siptosis
unzip /home/stsuser/downloads/tmp_SipToSis.zip (fix file name as needed)
chmod +x SipToSis_linux
skype &
login or create your skype account.
./SipToSis_linux
accept API request.
At this point you should be able to make echo test from an ATA,Softphone or PBX using the 55 shortcut and the SipToSis contact url.
PBX users should setup SipToSis to register with the PBX before going further.

Single channel users only
chmod +x stsTrunk_linux
gedit (or vi) stsTrunk_linux
runuser=stsuser
scriptpath=/home/stsuser/siptosis
displayMethod=XVFB

Single channel boot setup
su
gedit (or vi) /etc/rc.local
Add following line before exit 0:
su -l stsuser -c "/home/stsuser/siptosis/stsTrunk_linux boot"
Note: if using snd-dummy, make sure modprobe is before siptosis startup command.
exit

Pulseaudio removal
sudo apt-get remove pulseaudio then reboot.
If you didn't have a sound card when installing Ubuntu run:
sudo alsactl init

Patching snd-dummy for more streams:

Ubuntu Procedure
Alsa dummy.c modification:
Get package Driver (alsa-driver) 1.0.22.1 from Alsa Project Download
cd /usr/src
sudo tar jxvf /pathtodownload/alsa-driver-1.0.22.1.tar.bz2
cd /usr/src/alsa-driver-1.0.22.1/alsa-kernel/drivers
Change line 152:
static int pcm_substreams[SNDRV_CARDS] = {[0 ... (SNDRV_CARDS - 1)] = 8};
to:
static int pcm_substreams[SNDRV_CARDS] = {[0 ... (SNDRV_CARDS - 1)] = 128};
cd /usr/src/alsa-driver-1.0.22.1
sudo ./configure
sudo make
sudo make install
reboot
more /proc/asound/version - should show Alsa Driver version 1.0.22.1
This patch also works on 1.0.23/1.0.24 driver except it's line 66 instead.

There is some good info for compiling Alsa here.

Once the new snd-dummy is in place configure all skype clients (Mic/Spkrs/Ring) - set to Dummy, Dummy PCM (hw:1,0) or whatever it ends up as.

When installing skype to the centos 5 server, I follow the siptosis website instruction. In case you can't find the older skype, you may need to follow this link to install

http://punkts.org/trac/wiki/Skype22ForCentOS5

I copy the page information for our users as I find the browsing speed to this site is very slow

Package, install Skype 2.2.0.25 on CentOS 5 ¶

CentOS 5 has its own GCC Standard C++ Library package, but it is relatively old:

$ rpm -q --provides libstdc++-4.1.2-48.el5.i386 |grep GLIBC
libstdc++.so.6(GLIBCXX_3.4)  
libstdc++.so.6(GLIBCXX_3.4.1)  
libstdc++.so.6(GLIBCXX_3.4.2)  
libstdc++.so.6(GLIBCXX_3.4.3)  
libstdc++.so.6(GLIBCXX_3.4.4)  
libstdc++.so.6(GLIBCXX_3.4.5)  
libstdc++.so.6(GLIBCXX_3.4.6)  
libstdc++.so.6(GLIBCXX_3.4.7)  
libstdc++.so.6(GLIBCXX_3.4.8)  
$

Precompiled version of Skype 2.2 Beta for Linux requires a slightly newer version, libstdc++.so.6(GLIBCXX_3.4.9). Will install the libstdc++ package from Fedora 10, and make sure that it won't overwrite the one that came with the CentOS.

   1. Download, install the GCC Standard C++ Library RPM from the Fedora 10 archive.

# rpm -i --relocate /usr/lib=/usr/local/lib \
    http://archives.fedoraproject.or ... ++-4.3.2-7.i386.rpm
#
# rpm -ql libstdc++-4.3.2-7
/usr/local/lib/libstdc++.so.6
/usr/local/lib/libstdc++.so.6.0.10
#
# ( cd /usr/local/lib ; ls -log libstdc++* )
lrwxrwxrwx 1     19 Apr  6 12:00 libstdc++.so.6 -> libstdc++.so.6.0.10
-rwxr-xr-x 1 954544 Nov  5  2008 libstdc++.so.6.0.10
#
# whereis libstdc++.so.6
libstdc++.so: /usr/lib/libstdc++.so.6 /usr/local/lib/libstdc++.so.6
#

Now will download a few files, build and install the RPM.

   2. Download statically compiled version of Skype (to avoid installation of Qt 4).

# cd /usr/src/redhat/SOURCES
# wget http://www.skype.com/go/getskype ... ic-2.2.0.25.tar.bz2

   3. Download a simple patch, and a .spec file.

# url=http://punkts.org/sw/el5
# wget $url/skype-2.2.0.25-shell.patch
# wget $url/skype.sh
#
# cd /usr/src/redhat/SPECS
# wget $url/skype.spec
#

   4. Build, then install the package.

# rpmbuild -bb skype.spec
[...]
#
# rpm -i /usr/src/redhat/RPMS/i386/skype-2.2.0.25-*.i386.rpm
#

What was the patch needed for?

$ rpm -ql skype |grep desktop
/usr/share/applications/skype.desktop
$
$ grep Exec /usr/share/applications/skype.desktop
Exec=skype.sh
$
$ rpm -ql skype |grep bin/skype
/usr/bin/skype
/usr/bin/skype.sh
$
$ pr -to3 /usr/bin/skype.sh
   #!/bin/sh
   LD_PRELOAD=/usr/local/lib/libstdc++.so.6 /usr/bin/skype
$

Upgrade to CentOS 5.6 ¶

If you'd followed instructions given above, and now are trying to upgrade your system to CentOS 5.6, you may encounter the following error:

# yum update
[...]
ERROR with rpm_check_debug vs depsolve:

To work around this problem uninstall the libstdc++-4.3.2-7 package, upgrade libstdc++ to the version that comes with CentOS 5.6, and then install the libstdc++-4.3.2-7 package back in place.

# rpm -e --nodeps libstdc++-4.3.2-7
#
# yum update libstdc++
[...]

Updated:
  libstdc++.i386 0:4.1.2-50.el5                 libstdc++.x86_64 0:4.1.2-50.el5               

Dependency Updated:

For those using siptosis, I think you should not install more than one trunk if you do not have the trunk builder. For me, even I paid for the trunk builder before, when I want to manually create more trunks, I still encounter various problems e.g. port setting.

The trunk builder can help you to create the appropriate files and settings.

In my case, I can now manage to create 11 trunks (migrating back my VM image to the real server)
