SIP Testing

The emutel™ SIP | Harmony is a highly efficient, cost-effective and flexible tool, invaluable for use in the development, performance verification and pre-deployment testing of many types of VoIP equipment.

The emutel™ SIP | Harmony is a hardware based solution for load, stress, functional and interoperability testing of VoIP (SIP and H.323 including signalling and media traffics). The emutel™ SIP | Harmony provides the capabilities to test SIP and H.323 implementation, verify protocol compliance, proxy servers, Registrars, SIP endpoints and user agents.

The emutel™ SIP | Harmony is very flexible and scalable solution, single system can be configured with up to 8 Ethernet interfaces to generate SIP and H.323 traffic with capability to daisy chain expansion allowing user to cascade up to 8 units together and operate as a single system managed from one control application:

  • Windows Control Suite (drag and drop scripting engine)
  • Web-Interface (test script adjustment and reporting)
  • Command Line Interface (full control and results)

Interoperability Testing with the emutel™ SIP Harmony

The emutel™ SIP | Harmony can be intergrated with emutel Harmony and generate calls between SIP and legacy interfaces. This feature is very useful for gateway and MSAN testing. The emutel™ SIP | Harmony can generate the call through the DUT and answer on the other side. In addition to that emutel™ Harmony allows automate testing of the performance and functionality between multi interfcaes:

  • SIP to ISDN PRI ( E1/T1/J1) and BRI ( both BRI-U and BRI-S )
  • SIP to PSTN and Analog to SIP
  • ISDN (PRI and BRI) to SIP

SIP Equipment Regression Testing

The emutel™ SIP | Harmony is designed to easily automate the task of regression testing, ensuring testing can be carried out in a repeatable manner. Regression testing capability helps to verify that new releases and updates don’t affect stability or quality of the product.

Comprehensive Testing solution for SIP

  • SIP Bulk Call Generator.
  • Easy to use, drag-and-drop script building with the Harmony Script Composer.
  • Off-line script creation ensures the most productive use of emutel™ Harmony at all times.
  • Pre-written scripts provided for most typical test scenarios.
  • Pre-defined call load distribution sequences to simulate real world conditions.
  • GPS time synchronisation for distributed systems across a network.
