Software Requirements

The following software is required to be installed:

Microsoft .NET Framework 3.5 SP1
Microsoft .NET Framework 4.8
Windows PowerShell 1.0

The Mitel Communication Service can not be installed on a Domain controller or Small Business Server

Virtualization Environments

Mitel Communication Service is supported in a virtual environment. The supported environments are listed in the table below.

Environment	Supported?
VMWare vSphere ESXi v5.1 or greater
Hyper-V 2012 R2 or greater

To ensure maximum performance for SQL server in a virtual environment please ensure that each virtual CPU is configured with a minimum of four cores per socket

Co-Hosting with Xarios Call Recorder

If the MCS is being installed on the same server as a Xarios Call Recorder, it is advisable to change the following settings so that there are no clashes between the products:

Website Port

By default, both products will host their websites on port 80. To access the products individually, one of the websites must be reconfigured within IIS to use a different port. The website can then be accessed by appending the port to the URL:

http://[server_name]:81

Be aware that the port will be reset to 80 after by any upgrade applied to the system.

Database Backup & Log Archive Directories

By default, both Xarios Call Recorder and MCS use the same folders for database backups and log archives. Both of these locations need to be changed otherwise files will be overwritten.
