In this post, I am going to talk about how to configure FreeSWITCH in a high availability active-passive schema. The active-passive approach will share a floating IP between your VoIP switches and when one gets off-line, the passive one will take control over the IP and it will get the load. For more information about how this works, I strongly suggest you read my article about the High Availability Cluster Overview; you will understand what you are going to do.
This article will assume the following:
- You know the basics of Corosync and Pacemaker
- You already have installed Corosync and Pacemaker (installed, but not configured)
- You know how to configure your database in active-active cluster schema (regardless if it is MySQL/MariaDB or PostgreSQL)
- You know how to sync files between your FreeSWITCH servers.

Roundcube is awesome webmail. The most complete I have ever seen so far. It's fancy, look and feel combined with its IMAP access makes it not only very intuitive but to be synchronized with other clients. Well, if you are familiar with IMAP protocol you will understand why. Anyway, you can go to the Roundcube official website to read about the multiple capabilities this software has.
One thing that Roundcube lacks is a Calendar, similar to the Google Calendar. Lucky us, Kolab the open source project, has published a calendar plugin for Roundcube. I will talk here how I manage to install it under my ISPConfig3 web hosting server.

So it was about time, and I had to renew my old trust Acer V5 15" i5 Laptop. After digging and digging I decided to get an HP OMEN 17.3" i7-8750H Laptop. Although it is hardware built for gamers, the fact that it has 12 CPU cores makes it really attractive for coders and people who need power for other things than playing.
I will write here how I managed to make it work almost flawlessly under Linux Mageia 7.
