SIP and H.323 Call Generator

emutel™ SIP Harmony Overview

SIP | Harmony's SIP and H323 Call Generation and Termination Capabilities

SIP Harmony has strong Call Generation capabilities. Using the SIP | Harmony 'Composer' application, scripts can be quickly created to generate high volumes of calls. Once calls are established they can be cleared down straight away or held active for any period of time to simulate different call lengths. The SIP | Harmony is also capable of terminating calls, so complete wraparound testing of any piece of equipment can be carried out.

Control Interface

Windows Applications

A suite of powerful and intuitive Windows-based applications enables you to quickly and easily design and run multiple test scenarios to verify performance, functionality, capacity and interoperability of the device under test.

Web Applications

The emutel Harmony can be controlled using an Internet Web browser, so with a click of the mouse either a single script or a number of scripts can be initiated to run, after which a test report is generated giving the status of each test.

Command Line Interface

The Harmony may be controlled by using command line interface (CLI) commands and parameters. To access the CLI, the user must login to the Harmony using a Telnet or a SSH session. After starting a telnet or SSH connection to a Harmony using its IP-Address, the user will be prompted to enter the username and password. To transfer files to and from the Harmony, a TFTP server is required on the controlling computer..
