Python Scripting for Automation and Remote Access of Voice Quality Testing
The VQuad™ and Voice Quality Testing (VQT) Python libraries provide a range of Python functions which can be used to remotely or locally control these two applications. The VQuad™ library provides the functionality of the existing VQuad™ Command Line Interface (CLI) as well as the ability to run prewritten scripts sequentially. The VQT library can be used to run automatic and manual VQT tests with custom settings.
Python for VQuad™ works by connecting to the existing VQuad™ CLI and using a portion of the CLI commands to make simple functions. This connection to the CLI makes the library fast and responsive. Python scripts can perform a variety of Call Control and Audio operations on any device associated with the VQuad™ system. Additionally, access to the original CLI functions is possible through use of the VQuad™ library and the Python ctypes library.
Python for VQT works by connecting to the existing VQT CLI and using a portion of the CLI commands to run manual and automated VQT tests. Class variables are linked to the settings for each test and can be changed easily.
Main Features
- Python scripts support accessing VQuad™ and VQT functionalities remotely
- Controls VQuad™ and VQT nodes located at various destinations
- Automation with enhanced Python scripting and remote operation includes traffic generation, call control, and automated scheduling of operations
Command Line Interface (CLI) for remote access
VQuad™ provides full support for CLI on both Windows® and Linux environment. VQuad™ CLI also supports both IPv6 and IPv4.
The VQuad™ Command Line Interface (CLI) is designed to remotely access various application functionalities and thus controlling VQuad™ nodes located at various destinations.
The VQuad™ Remote Access (Client) allows VQuad™ operations to be remotely controlled by one (or several) VQuad™ clients over a LAN, WAN, or Internet.
All Call Control functions, and traffic simulation functions are supported. These includes - Load Call Control Script Configuration, Load VQuad™ Master Configuration, Start Stop Call Control Script, Place Call, Answer Call, Disconnect Call, Set and Get Log Files, and many other operations. It also supports traffic functions such as Send and Record Voice Files, Transmit and Detect Digits, Send and Detect Tones, Send and Receive Fax, OWD/RTD Correlation, and Stop Traffic.
