Key Features
- Voice Quality Metrics
▫️Objective MOS scoring using POLQA® and PESQ®.
▫️Support for narrowband, wideband, and super-wideband codecs (AMR-NB/WB, EVS, Opus). - Active VoIP/VoLTE Testing
▫️SIP and raw RTP call support.
▫️Encode/transmit speech samples, decode and analyze received streams. - Packet Impairment Simulation
▫️Define precise patterns of delay, jitter, or packet loss.
▫️Reproduce real-world conditions by importing overlays from live captures. - Codec Management
▫️Manage codec switching and rate adaptation.
▫️Overlay tools for Codec Mode Requests (CMR) synchronized with speech transmissions. - Network KPIs
▫️Measure packet loss, jitter, and SIP message timing.
▫️Identify codec or network-related performance issues. - MultiDSLA Integration
▫️Centralized configuration, orchestration, results collection, and reporting.
▫️Combine with DSLA (hardware) and OSS (smartphone-based) agents for end-to-end QoE analysis.
Benefits for the Client
- End-to-end realism – test VoIP/VoLTE services with actual SIP endpoints.
- Deep QoE insight – beyond MOS, capture KPIs and root cause indicators.
- Flexible impairment testing – reproduce degradations to assess resilience.
- Versatile codec coverage – validate next-gen services including EVS and Opus.
- Efficient integration – part of the MultiDSLA ecosystem for lab and live environments.
Why VPP is Different ?
- Software-based scalability – deployable across distributed test networks.
- Advanced impairment overlays – unique simulation of jitter, loss, or codec shifts.
- Codec-rich testing – from legacy to 5G-ready codecs (EVS).
- Centralized supervision – fully integrated with MultiDSLA controller and reporting.
- Trusted reference tool – widely used by operators and test labs worldwide.
Typical Use Cases
