make
make install
make progdocs
make samples
make config

chkconfig asterisk on

Create Asterisk user/group and edit permissions:

groupadd -g 5060 asterisk
adduser -c “Asterisk Telephone Server” -d /var/lib/asterisk -g asterisk -u 5060 asterisk

chown –recursive asterisk:asterisk /var/lib/asterisk
chown –recursive asterisk:asterisk /var/log/asterisk
chown –recursive asterisk:asterisk /var/run/asterisk
chown –recursive asterisk:asterisk /var/spool/asterisk
chown –recursive asterisk:asterisk /usr/lib/asterisk

chmod –recursive u=rwX,g=rX,o= /var/lib/asterisk
chmod –recursive u=rwX,g=rX,o= /var/log/asterisk
chmod –recursive u=rwX,g=rX,o= /var/run/asterisk
chmod –recursive u=rwX,g=rX,o= /var/spool/asterisk
chmod –recursive u=rwX,g=rX,o= /usr/lib/asterisk

Edit /etc/asterisk/asterisk.conf:

astrundir => /var/run/asterisk
runuser = asterisk ; The user to run as
rungroup = asterisk ; The group to run as

Edit /etc/sysconfig/asterisk:

Remove comment out

AST_USER=”asterisk”
AST_GROUP=”asterisk”

Install app_swift:

Appswift is at http://76.164.171.235/gf/project/app_swift/frs/?action=FrsReleaseBrowse&frs_package_id=7, it adds app_swift, which integrates with Cepstral TTS and makes creating prompts in your dialplan easy.

cd /usr/src
wget http://76.164.171.235/gf/download/frsrelease/110/142/app_swift-2.0.1-ast1.8.tar.gz
tar -xvzf app_swift-2.0.1-ast1.8.tar.gz
cd app_swift-2.0.1-ast1.8
make
make install

Install php5 for scripting:

yum install php php-cli

Install g729 and g723 codecs:

cd /usr/src
wget http://asterisk.hosting.lv/bin/codec_g723-ast18-gcc4-glibc-pentium4.so
wget http://asterisk.hosting.lv/bin/codec_g729-ast18-gcc4-glibc-pentium4.so
cp codec_g729-ast18-gcc4-glibc-pentium4.so /usr/lib/asterisk/modules/codec_g729.so
cp codec_g723-ast18-gcc4-glibc-pentium4.so /usr/lib/asterisk/modules/codec_g723.so

Asterisk Fax:

Order free license key from digium at store.digium.com first.

Then:

cd /usr/src/
mkdir astfax
cd astfax
wget http://downloads.digium.com/pub/register/x86-32/register
wget http://downloads.digium.com/pub/telephony/fax/benchfax/x86-32/benchfax-1.1.0-x86_32

chmod 500 register
chmod 500 benchfax-1.1.0-x86_32

./benchfax-1.1.0-x86_32

This will tell you which version of Asterisk Fax to use. Then go to the fax selector at   http://www.digium.com/en/docs/FAX/faa-download.php

Pick the one suggested by bench fax, in our case (a 32 bit i686 Linux):

wget http://downloads.digium.com/pub/telephony/fax/res_fax_digium/asterisk-1.8.4/x86-32/res_fax_digium-1.8.4_1.3.0-i686_32.tar.gz

tar xvzf res_fax_digium-1.8.4_1.3.0-i686_32.tar.gz

cd /usr/src/astfax/res_fax_digium-1.8.4_1.3.0-i686_32
cp res_fax_digium.so /usr/lib/asterisk/modules/
cp res_fax_digium.conf /etc/asterisk/

Now you can test your basic installation via

asterisk -vvv -c

If all is well, you can run

service asterisk start

to run it as a service. I have my config files from previous installs, so I first copied them back to /etc/asterisk and I was good to go.
