How to Download and Compile Asterisk on CentOS

In order to download the source, visit http://www.downloads.digium.com/pub/telephony/asterisk/ and select one of the tar.gz links (http://downloads.asterisk.org/pub/telephony/certified-asterisk/certified-asterisk-11.2-cert2.tar.gz for example)

In a terminal, change to the /usr/src directory then download the Asterisk tarball (copied .tar.gz link)

1. cd /usr/src

2. wget http://downloads.asterisk.org/pub/telephony/certified-asterisk/certified-asterisk-11.2-cert2.tar.gz

After this is done, extract the tar file.

3. tar -zxvf certified-asterisk-11.2-cert2.tar.gz

Change to the Asterisk source directory

4. cd certified-asterisk-11.2-cert2/

Lastly, compile Asterisk

5. ./configure

6. make menuselect

7. make

8. make install

9. make samples (this installs a set of sample config files and is optional)

10. make config

Please note that if you have a Digium card or need Asterisk to work with DAHDI you need to install DAHDI first.
