I want to thanks the FusionPBX community for their sponsor. Without the given support this new capability wouldn't be possible. Today I have published into the FusionPBX pull requests 3972 and 3973 (for FusionPBX 4.4). This new capability gives your PBX the parent-child domain. This means an admin user will be able to manage more than one domain without being super-admins. The best case scenario for this is new capability is the reseller one.
Once it is configured, you may give access to a reseller and let him manage their domains. I will explain how it works.
This is not a new capability. Since 4.2 (maybe before), FusionPBX has offered this capability. When a caller sends a voicemail message, FusionPBX is able to convert it to a text as well. This is really handy, not everybody has the patience to listen to the sounds. Sometimes, reading is faster. This service is possible because of the Bing API from Microsoft.
Since 2018 (not sure when), Microsoft has deprecated Bing API in favour of Azure. This means that legacy users may still use it (for a while, we don't know yet when it will drop completely) but new users who want to use the transcribe service won't be able to do it. Not using Bing way.
I will explain here how I figure out to make it work with Azure.
MariaDB Galera Cluster is a synchronous multi-master cluster for MariaDB. It is available on Linux only, and only supports the XtraDB/InnoDB storage engines (although there is experimental support for MyISAM - see the wsrep_replicate_myisam system variable).
Starting with MariaDB 10.1, the wsrep API for Galera Cluster is included by default. This is available as a separate download for MariaDB 10.0 and MariaDB 5.5.
MariaDB has one of the best and easiest solutions to do a Master-Master replication: Galera. Galera uses WSREP, which it is responsible for maintaining all the Database nodes in the cluster in sync. This means, after changing one record on node A, it is just a matter of seconds to see the change on node B.
I will talk in this article how I did this configuration using MariaDB 10.1.x. Remember you can install MariaDB under Centos 6 and 7 by using OKay's repository.
