How to – Setup a slave DB for a scratch installed ViciDial

This Article will go over how to setup a slave database server for your ViciDial cluster when using a scratch installed server bunch. For this particular example I have used Alma Linux 8.5 which installs Mysql 10.3.28, if you followed my scratch instructions. This process was a pain in the arse, but after much trial and error I was able to get it done and here is how I did it:

Step 1 – Edit the MySQL config file

Add these lines to /etc/my.cnf below [mysqld] on both the master and slave database:

datadir = /srv/mysql/data
server-id       = 1
slave-skip-errors = 1032,1690,1062

Step 2 – Create the slave user on both servers

Go into MySQL and create the slave user and do this on both servers

CREATE USER 'slave'@'localhost' IDENTIFIED BY 'slave1234';
CREATE USER 'slave'@'%' IDENTIFIED BY 'slave1234';
grant replication slave on . to slave@'%' identified by 'slave1234';
grant replication slave on . to slave@'localhost' identified by 'slave1234';
flush privileges;
Create slave user on both the master and slave DB

Step 3 – Change some setting on the slave DB

Now we need to change some of the settings for the slave DB and add a couple more lines. Change the server-id to 2 instead of 1 in /etc/my.cnf and add the read_only=1 and report-host=whatever the slave DB host is

# read only yes
# define own hostname

Step 4 – Restart the MySQL services on both servers

Run the following command on both servers:

service mysql restart

Step 5 – Create the MySQL dump to send over to the slave DB from the master

We need to create the MySQL dump and send it over to the slave using the scp command like so:

mkdir /home/mariadb_backup
mariabackup --backup --target-dir /home/mariadb_backup -u root
Create MySQL dump file

Once thats done go ahead and zip up the files and send the file over by typing the following:

cd /home/mariadb_backup
zip -r *

Why we are here, lets lock the MySQL tables on the master:


Step 6 – Connect to Slave DB and extract the files and load it into the slave

ssh into your slave db server and change directory to /root then create the folder and extract the files like so:

cd /root
mkdir mariadb_backup
mv mariadb_backup/
cd mariadb_backup/
systemctl stop mariadb
rm -rf /var/lib/mysql/*

Now run the following commands that are BOLD to import the MySQL dump and set its position to match that of the master.

# run prepare task before restore task (OK if [completed OK])
[root@node01 ~]# mariabackup --prepare --target-dir /root/mariadb_backup

Step 7 – Unlock the Master DB

Now go back into the master DB and unlock the tables:

unlock tables;

Step 8 – Set the Slave DB in ViciDIal

Now you can set the slave server info in ViciDial by going into the admin GUI and going into system settings. Set the slave DB server IP and choose which reports you want to display from it.

Well, this has been quite the nightmare to get it done and hopefully I can save some of you some time with this article. If you have any problems feel free to join our Skype Live Support Channel and someone will be willing to help.

How to – Setup an archive server


How to – Setup an archive server

This article is going to go over how to “scratch” install an archive server on CentOS 8, Rocky Linux or Alma Linux. You can pretty much follow it for OpenSuSe as well but there would be some small variations for installing vsftpd.

Step 1 – Install and setup vsftpd

The first thing we have to do is install and properly configure vsftpd.

yum install vsftpd
nano /etc/vsftpd/vsftpd.conf
paste the following at the very bottom:

vsftpd config
vsftpd.conf config
nano /etc/vsftpd/user_list
(add "cronarchive" to the bottom)

useradd -m -d /home/archive/ cronarchive
passwd cronarchive 
(set the pw u want)

mkdir -p /home/archive
chmod -R 777 /home/archive

Step 2 – Set your archive server in script

Below is a settings example to put during the script which can be run by running the following commands. This has to be run on all asterisk servers:

cd /usr/src/astguiclient/trunk/
archive setup
archive setup during script

Step 3 – Turning on the cronjob to send the recordings over to the archive server

Changing this cronjob has to be done on all asterisk servers. You have to remove the # in front of this line by typing “crontab -e” and scrolling until you find it:

2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47,50,53,56,59 * * * * /usr/share/astguiclient/ --MP3 --run-check
crontab -e

Step 4 – Changing the Apache alias for the recordings

Last thing we need to do is change the alias for the recordings on the archive server as shown below:

nano /etc/httpd/conf.d/record.conf

Alias /RECORDINGS/ "/home/archive/"

<Directory "/home/archive">
    Options Indexes MultiViews
    AllowOverride None
    Order allow,deny
    Allow from all
    Require all granted
        <files *.mp3>
            Forcetype application/forcedownload
Apache alias
Apache alias

Well, thats all there is to it, hopefully this will help some of you with improving your cluster setups and properly setting up an archive server.

How to – Create a DNC call menu for people to remove themselves

DNC Call Menu

How to – Create a DNC call menu for people to remove themselves

This article will go over the process to create a call menu or IVR that allows people to remove themselves from the calling list by pressing a key. The FTC is cracking down on VoIP carriers to make sure their clients are using this feature and it will end up getting your VoIP routes shut down if you do not have this feature on your system.

DNC Call Menu
DNC Call Menu

Step 1 – Create a new Call Menu

Go to the admin GUI for ViciDial and click on inbound, then “Add a new call menu”

add a new call menu
Add a new call menu

Step 2 – Fill out the required fields as highlighted in the picture below

For this example we have used some of the built in sounds for ViciDial and piped them together ( | ) to create the voice prompt we want as well as the post message to be played after they opt out. This example only shows 1 option to be pressed, but it can be amplified even more by setting up other options such as leaving a voicemail, asking for a callback, routing to an operator or anything else you can pretty much do with the system.


Call Menu Options

Step 3 – Attach the call menu to you inbound group that your DID’s are routed through

You can get to your ingroup also through the inbound menu option in the admin GUI. Once your in your inbound group attached to your DIDs, go down to no agent queueing option and set it to Y, then set the route to call menu as shown below:

Inbound group for DIDs
Inbound Group for DID’s

That’s all there is to it, hopefully you guys head my advice and do this now before it happens to you via your carrier, cause trust me when I tell you, its coming. If you need additional help, feel free to stop by our live support on Skype by clicking here.

How to – Setup a ViciDial Cluster

ViciDial Cluster

How to – Setup a ViciDial Cluster

This article is going to go over the steps I suggest to take in order to setup a ViciDial Cluster. I do things a little different when it comes to this to prepare for worst case scenario that a server may have problems and have to be taken offline, I install all services to each server, such as apache, mysql and asterisk this way if need be, they each can take on additional roles to cover for a server having to be taken out of production. Obviously this is going to assume you have ViciDial already installed on each server with all roles ready to go. To do so you can follow any one of my articles for scratch installs or you can just use an ISO to install of which I suggest using Vicibox v9.0.3 over V10 because of the issues with the V10 firewall and dynamic portal not working correctly, even if you do apply my fix, I find V9 to be more stable.

ViciDial Cluster
ViciDial Cluster

Step 1 – Install Vicidial on each server

As I said above, I suggest installing all services on each server and just leaving the ones not needed for each box, disabled until needed. So if you are using an ISO install instead of one of my scratch instructions, for the purpose on this article, lets say ViciBox v9.0.3. The first thing you need to do after loading v9 is to upgrade the operating system from Leap 15.1 to Leap 15.2 using these instructions, because Leap 15.1 is end of life(no more updates). After that use the command, vicibox-install and choose Y(yes) for the options shown in the picture below:

ViciBox Installer

Repeat this process on each server and then move on to step 2.

Step 2 – Turn off services not needed on each server role

Now we need to disable services not needed on each server to save on resources, but this way they are there if they are needed in the future.

  • DB Server: systemctl disable apache2;systemctl disable asterisk
  • Web Server: systemctl disable mysql;systemctl disable asterisk
  • Asterisk Servers: systemctl disable mysql

We want to leave apache running on the asterisk servers so we can install webrtc for webphones

Step 3 – Run the script on each server

Now we want to link them all together by running the script located in the source directory for vicidial, follow the following commands to get to and run it:

cd /usr/src/astguiclient/trunk

Now follow the prompt and answer them accordingly. The pictures below will show the choices needed for each server role except make sure you set the IP for the DB server on all the rest instead of localhost.

DB Server and Web Server

DB Server

For the web server make sure you put the DB server IP instead of localhost

Asterisk Servers

Only use 5 and 7 on ONE asterisk server, not all, the rest put 123468

Make sure you only put 5 and 7 keepalives on one asterisk server, the rest you should only choose 123468.

Step 4 – Add them to the GUI for ViciDial

Now we need to add them into the GUI for Vicidial by going to Admin then servers

Go to Servers in the Admin area

Once you are here, click “Add a new server”

Once you are here, click "Add a new server"
Once you are here, click “Add a new server”

Fill out the fields accordingly and click submit

Add a new server

Now for the DB and web server turn the options to N(no) where you see highlighted below:

Active server, Active Asterisk server and Active agent server set to N

Now reboot all servers and then check your reports page to make sure all servers are set to green like shown below

ViciDial Cluster

That’s all there is to it, not as hard as you thought it would be, right? If you have any questions feel free to join our live support on Skype:

How to – use one dynamic portal for whitelisting and have it sync across an entire cluster

Dynamic Portal

How to – use one dynamic portal for whitelisting and have it sync across an entire cluster

This article will go over a method I have recently come up with in order to have your agents sign in through one dynamic portal and have their IP validated across all servers in the cluster.

Step 1 – Generate a SSH key

In your linux cli simply type “ssh-keygen” and just press enter for all default values with no password as shown below


Step 2 – copy the ssh key to the other servers you need it synced to

ssh-copy-id -i ~/.ssh/ (replace IP with the servers Ip’s as you do each one)

Type yes and then enter the servers root password, do these steps for each server in your cluster

ssh-copy-id -i ~/.ssh/

Step 3 – rsync the Dynamic IP firewall list to the other servers

Replace the IP’s with each one in your cluster and repeat this step for each

  • Vicibox9 users use this command: /usr/bin/rsync -a -e “ssh” /tmp/VB-DYNAMIC-tmp root@
  • Vicibox10 users use this one: /usr/bin/rsync -a -e “ssh” /tmp/dynamiclist-add-tmp root@
/usr/bin/rsync -a -e “ssh” /tmp/dynamiclist-add-tmp root@

Step 4 – Now add a cronjob to have this done every minute with one line for each server as shown below

  • ###Dynportal Sync
  • * * * * * /usr/bin/rsync -a -e “ssh” /tmp/dynamiclist-add-tmp root@
  • * * * * * /usr/bin/rsync -a -e “ssh” /tmp/dynamiclist-add-tmp root@

That’s all there is to it, now you can have your agents login through a single dynamic portal and sync it through to all servers in your cluster.

I hope this helps
