h1. This page will describe how to install OpenBSC with Asterisk using LimeSDR (Ubuntu 16.04)

<pre>

** Install Dependency

sudo add-apt-repository -y ppa:myriadrf/drivers

sudo apt-get update

#install core library and build dependencies

sudo apt-get install git g++ cmake libsqlite3-dev

#install hardware support dependencies

sudo apt-get install libsoapysdr-dev libi2c-dev libusb-1.0-0-dev

#install graphics dependencies

sudo apt-get install libwxgtk3.0-dev freeglut3-dev gnuplot

** Install LimeSuite

git clone https://github.com/myriadrf/LimeSuite.git

cd LimeSuite

mkdir builddir && cd builddir

git checkout v17.12.0

cmake ../

make -j4

sudo make install

sudo ldconfig

cd LimeSuite/udev-rules

sudo sh ./install.sh

Type “LimeSuiteGUI” on terminal to check GUI is running

</pre>

*Now build UHD driver and SoapySDR, SoapyUHD*

<pre>

***MAKE SURE YOU HAVE A FRESH INSTALL OR DO THIS TO REMOVE ALL UHD DRIVER FROM APT*****

sudo apt-get remove libuhd-dev libuhd003 uhd-host

#Then we start compile UHD driver (install all dependency)

sudo apt-get -y install git swig cmake doxygen build-essential libboost-all-dev libtool libusb-1.0-0 libusb-1.0-0-dev libudev-dev libncurses5-dev libfftw3-bin libfftw3-dev libfftw3-doc libcppunit-1.13-0v5 libcppunit-dev libcppunit-doc ncurses-bin cpufrequtils python-numpy python-numpy-doc python-numpy-dbg python-scipy python-docutils qt4-bin-dbg qt4-default qt4-doc libqt4-dev libqt4-dev-bin python-qt4 python-qt4-dbg python-qt4-dev python-qt4-doc python-qt4-doc libqwt6abi1 libfftw3-bin libfftw3-dev libfftw3-doc ncurses-bin libncurses5 libncurses5-dev libncurses5-dbg libfontconfig1-dev libxrender-dev libpulse-dev swig g++ automake autoconf libtool python-dev libfftw3-dev libcppunit-dev libboost-all-dev libusb-dev libusb-1.0-0-dev fort77 libsdl1.2-dev python-wxgtk3.0 git-core libqt4-dev python-numpy ccache python-opengl libgsl-dev python-cheetah python-mako python-lxml doxygen qt4-default qt4-dev-tools libusb-1.0-0-dev libqwt5-qt4-dev libqwtplot3d-qt4-dev pyqt4-dev-tools python-qwt5-qt4 cmake git-core wget libxi-dev gtk2-engines-pixbuf r-base-dev python-tk liborc-0.4-0 liborc-0.4-dev libasound2-dev python-gtk2 libzmq-dev libzmq1 python-requests python-sphinx libcomedi-dev python-zmq  python3-dbg libgps-dev python3-dev python3-pip python3-tk python3-lxml python3-six

** Install UHD

git clone https://github.com/EttusResearch/uhd

cd uhd

git tag -l

...

release_003_009_004

release_003_009_005

release_003_010_000_000

# Example: For UHD 3.10.2.0: 

then type this command :  

git checkout release_003_010_002_000 (get the latest is fine)

then build: 

cd host

mkdir build

cd build 

cmake ../

make

sudo make install

sudo ldconfig

export LD_LIBRARY_PATH=/usr/local/lib

----now find UHD:

uhd_find_devices

** Install SoapySDR and SoapyUHD 

git clone https://github.com/pothosware/SoapySDR.git

cd SoapySDR

mkdir build

cd build

cmake ..

make

sudo make install

sudo ldconfig

git clone https://github.com/pothosware/SoapyUHD

cd SoapyUHD

mkdir build

cd build

cmake ..

make

sudo make install

sudo ldconfig

----try run command to find LimeSDR :

SoapySDRUtil --find

next....

</pre>

*Build osmo-trx*

<pre>

mkdir osmo

cd osmo

git clone https://github.com/osmocom/osmo-trx.git

cd osmo-trx

autoreconf -fi

./configure

make -j5

make check

sudo make install

sudo ldconfig

run on terminal: (too see its connect with SoapyUHD and UHD)

osmo-trx-uhd

next …..

</pre>

*Build Osmocom OpenBSC with all stacks* 

<pre>

DEPENDENCY (use synaptic when they ask more dependency when build)

sudo apt install libpcsclite-dev libtalloc-dev libortp-dev libsctp-dev libmnl-dev libdbi-dev libdbd-sqlite3 libsqlite3-dev sqlite3 libc-ares-dev 

cd osmo

git clone git://git.osmocom.org/libosmocore

cd libosmocore

autoreconf -fi

./configure

make -j5

sudo make install

cd osmo

git clone git://git.osmocom.org/libosmo-abis

cd libosmo-abis

autoreconf -fi

./configure

make -j5

sudo make install

cd osmo

git clone git://git.osmocom.org/libosmo-netif

cd libosmo-netif

autoreconf -fi

./configure

make -j5

sudo make install

cd osmo

git clone git://git.osmocom.org/libosmo-sccp

cd libosmo-sccp

autoreconf -fi

./configure

make -j5

sudo make install

cd osmo

git clone git://git.osmocom.org/libsmpp34

cd libsmpp34

autoreconf -fi

./configure

sudo make install

cd osmo

git clone git://git.osmocom.org/osmo-ggsn

cd osmo-ggsn

autoreconf -fi

./configure

make -j5

sudo make install

git clone git://git.osmocom.org/openbsc

cd openbsc/openbsc

autoreconf -fi

./configure --enable-smpp --enable-osmo-bsc --enable-nat

make -j5

sudo make install $$ sudo ldconfig

cd osmo

git clone git://git.osmocom.org/osmo-bts.git

cd osmo-bts

autoreconf -fi

./configure --enable-trx

make

sudo make install

sudo ldconfig

</pre>

*Now installing “asterisk & osmo-sip-connector"*

<pre>

--Install dependencies:

The extension we are about to make requires to install some additional packages.

sudo apt-get install libsofia-sip-ua-glib-dev

sudo apt-get install asterisk

--Install osmo-sip-connector:

cd osmo

git clone git://git.osmocom.org/osmo-sip-connector.git

cd osmo-sip-connector

autoreconf -fi

./configure

make

sudo make install $$ sudo ldconfig

setting path for configuration

gedit ~/osmo/openbsc.cfg (file attached)

gedit ~/osmo/osmo-bts.cfg (file attached)

gedit ~/osmo/osmo-sip-connector.cfg (file attached)

--Asterisk configuration

The following section will discuss a minimal Asterisk configuration that is able to route calls between mobile phones. The described case assumes a freshly installed Asterisk with virgin configuration files. In the following we will edit extensions.conf and sip.conf which can be found in the /etc/asterisk directory. The example below is not special to GSM, its rather a normal SIP-trunk configuration.

Set up the sip-trunk towards osmo-sip-connector:

The first that has to be taken care of is the connection to osmo-sip-connector. The following lines need be appended to sip.conf:

cd /etc/asterisk/

sudo gedit sip.conf

[GSM]

type=friend

host=127.0.0.1

dtmfmode=rfc2833

canreinvite=no

disallow=all

allow=gsm

context=gsmsubscriber

port=5069   

noted : (changing port with 5062 or 5060 if 5069 not working)

The connection is named GSM, this name will be used later to reference the connection when routing outgoing calls. The context name “gsmsubscriber” references the context where mobile originated calls are routed into the dialplan. 

Set up a dialplan to route calls:

Now Asterisk and osmo-sip-connector are connected. The following example introduces a very basic dialplan configuration to route calls between mobile phones. The following example can be added to extensions.conf:

cd /etc/asterisk

sudo gedit extensions.conf

[gsmsubscriber]

exten=>_XXXXX,1,Dial(SIP/GSM/${EXTEN})

exten=>_XXXXX,n,HangUp

</pre>

*Now how to run openbsc stacks:*

<pre>

** open terminal 

run:

osmo-nitb -c ~/osmo/openbsc.cfg -l ~/osmo/hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM -M /tmp/bsc_mncc

open new terminal

run:

osmo-bts-trx -c ~/osmo/osmo-bts.cfg

open new terminal

run:

osmo-sip-connector -c ~/osmo/osmo-sip-connector.cfg

open new terminal

run:

sudo asterisk -r

open new terminal

run:

osmo-trx-uhd -C ~/osmo/limesdr.cfg

open new terminal

run:

telnet localhost 4242

enable

</pre>

Now you running OpenBSC with Asterisk :-)
