Goip systemd service

cat /etc/systemd/system/goip.service

We should start goip service after mysql and we should be sure that it will autorestart on crash.

Asterisk & Self Registration Queue

Asterisk working systemd service

We will start asterisk after mariadb (for connecting res_odbc);
We run asterisk from user “asterisk”.

Working fail2ban for Asterisk (security log)

Hey, just another config draft from me. In that article we will enable fail2ban jail for asterisk on UDP/5060 via iptables.

In /etc/sysconfig/iptables we should allow UDP/5060 for all (if you want to enable only for your subnet why you need fail2ban? Just allow 192.168.1.0/24 and don’t read that article).

Installing goip sms server on Centos x64.

Installation requires: php <7. Just because or Chinese friends use mysql_ and not mysqli_ or PDO stuff.

cd /tmp

tar xvfz goip_install-v1.2*

Adding blacklist feature to Asterisk 16

Lets add blacklist feature to our Asterisk. We will use AstDB (CFIM/blacklist).

First of all lets add ability to add and remove numbers to our blacklist.

Open /etc/asterisk/extensions.conf via your favorite editor (nano, huh?)
