Key Features

Overlays are a unique way to easily reproduce and understand voice quality impairment.

VPP+ has two overlay modes:

The Packet Impairment Overlay defines a precise pattern of packet impairments.

The Rate Change Overlay defines transmit rate changes or Codec Mode Requests (CMR) synchronised to speech transmissions.

Both of these overlays may be constructed by the user with a graphical overlay designer.

Alternatively, the Packet Impairment Overlay may be based on a capture from a live network.

  • Test calls can be made with or without SIP server registration.
  • The VPP encodes and transmits real speech samples. It also receives and decodes the speech. All codecs that matter are supported, including EVS.
  • MultiDSLA Controller manages the configuration, runs the test call plan and stores the measurements for reporting and analysis.
  • VPP is highly flexible and can be configured in many ways to address specific test requirements.
  • With VoxPort Packet you have the tools to examine, understand and even reproduce VoIP network behavior.
