27. CallGenerator™

To perform audio quality measurements (AQM) involving calls to the fixed side, you need a CallGenerator to serve as the other party in the calls. See the User's Manual, chapters "AQM with ACU R2" and "AQM for CS Voice with AQM Modules".

How to install a CallGenerator is described in the document CallGenerator Installation Guide, which is included in the CallGenerator sales package. This document also states PC hardware and operating system requirements posed by the CallGenerator installation.

Please note the following:

The CallGenerator must be a version-numbered one (version 1.0 or later; version 1.1 required for "M2F Dial Answer Snippet") to be compatible with TEMS Investigation 23.2. Older CallGenerators have no version numbering.

The CallGenerator installation requires an English-language edition of Windows.

If the CallGenerator PC is not running Windows Server 2008 R2, make sure that you have Windows Management Framework (Windows PowerShell 2.0, WinRM 2.0, and BITS 4.0) installed. To check what version you have, run a command prompt as administrator and type $host.version. This command should return "Major" = 2. If it does not, download the correct software version via Windows Update or by following this link: ► support.microsoft.com/kb/968929. – In PowerShell, also check that Get-ExecutionPolicy returns "RemoteSigned". If you get a different response, run the command Set-ExecutionPolicy RemoteSigned.
