3) Move to /usr/src/ dir
cd /usr/src

4) Download asterisk there
wget downloads.asterisk.org/pub/telephony/asterisk/asterisk-13-current.tar.gz

5) Unpack it
tar zxvf asterisk-13-current.tar.gz

6) Goto directory asterisk-13
cd asterisk-13.24.1


7) Compile pjproject:

git clone git://github.com/asterisk/pjproject pjproject

cd pjproject

./configure --prefix=/usr --enable-shared --disable-sound --disable-resample --disable-video --disable-opencore-amr CFLAGS='-O2 -DNDEBUG'

./configure && make menuselect && make && make install


On successful configuration the following output will show on terminal.
