[root@ippbx src]# wget http://mirror.freepbx.org/modules/packages/freepbx/freepbx-15.0-latest.tgz
[root@ippbx src]# wget https://ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.gz
[root@ippbx src]# wget http://digip.org/jansson/releases/jansson-2.13.tar.gz
[root@ippbx src]# wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
[root@ippbx src]# wget http://downloads.asterisk.org/pub/telephony/libpri/libpri-current.tar.gz

[root@ippbx src]# tar xvf libtool-2.4.6.tar.gz
[root@ippbx src]# cd libtool-2.4.6
[root@ippbx libtool-2.4.6]# ./configure
[root@ippbx libtool-2.4.6]# make install

9.Compile and install DAHDI
If you don’t have any physical PSTN hardware attached to this machine, you don’t need to install DAHDI (For example, a T1 or E1 card, or a USB device). Most smaller setups will not have DAHDI hardware, and this step can be safely skipped.
