Make voice quality measurable.
VoLTE, VoIP, cloud UC, smartphones: measure the voice quality and delay of any endpoint objectively, to POLQA (ITU-T P.863) / PESQ. LAN remote control and a text command interface bring test automation and system integration.
Still judging call quality by ear?
As call infrastructure diversifies and UC moves to the cloud, objective voice-quality evaluation matters more than ever.
Fragmented call paths
VoLTE, VoIP, cloud UC, WebRTC: quality and delay vary widely by device and service.
UC-migration quality drops
Moving from on-prem PBX to cloud UC brings degradation and delay, hard to isolate without objective data.
Standards compliance required
Carriers and device makers must prove conformance to ITU-T P.863 (POLQA), 3GPP and more.
Legacy gear can't scale
Serial-bound with no remote measurement, GUI-only: no automation or integration.
Objective POLQA measurement, now remote and automatable.
VoicePinger 2 (ToyCAP2) is a purpose-built solution that measures voice quality and delay objectively, to international standards. It connects to any endpoint via a 3.5 mm audio jack and is controlled remotely over LAN.
Objective
POLQA (ITU-T P.863) / PESQ compliant: quality in numbers, not impressions.
Remote
Put the sending and receiving ends in different sites and measure end-to-end over LAN.
Automatable
A text command interface lets other systems drive it: test automation and CI/CD.
Four decisive upgrades over the original.
| Aspect | VoicePinger 1 | VoicePinger 2 |
|---|---|---|
| Control | Serial connection + a dedicated Windows app only | LAN Ethernet + text commands: drivable from other systems and scripts, enabling test automation and CI/CD. |
| Remote | Sending and receiving ends had to sit in the same place | Remote control over LAN: end-to-end measurement across different sites. |
| Delay | Pulses emitted by the VP unit only | DTMF-tone method: closer to real calls, with far better accuracy and flexibility. |
| Playback / record | The PC handled playback and recording (the unit only matched impedance) | The ToyCAP2 unit plays and records directly, then transfers files to the PC: a simpler setup. |
Everything you need to measure.
POLQA / PESQ measurement
Objective scoring for HD voice, VoLTE, VoHSPA and VoIP super-wideband.
DTMF delay & jitter
Real-time graphs of end-to-end delay and jitter, with CSV export.
LAN remote control
Place each end in a different site and measure end-to-end.
Command I/F & automation
A text-based Ethernet socket interface lets other systems and scripts drive it.
Browser-based operation
No dedicated app to install: operate measurements from a web browser.
Wav Comparator New
Compare two recordings by waveform and quantify the difference with two scores.
Measure two sites, exactly as they are.
Place a ToyCAP2 at each end and control both remotely from a single PC (web browser) over LAN. Measure voice quality and delay across real networks, site to site.
- True end-to-end over the real network
- Field measurement across domestic and overseas sites
- Connect any endpoint via a 3.5 mm audio jack

Wav Comparator (illustrative)
Wav Comparator lines up two WAV files for visual comparison and turns a subjective difference in sound into two objective scores.
- Degradation — scores the visual waveform difference
- ToyVQ — scores listening ease
- Also for conference calls and guidance/IVR audio, not just phone calls
Turn "sounds fine" into a standards-based score.
POLQA-based since its 2013 release; the 2023 second generation adds LAN remote control, a command interface, and Wav Comparator.
Objective measurement the press has relied on.
VoicePinger has measured voice quality against POLQA since its 2013 release. Its objective measurement has been featured in industry product news and in press comparisons of calling services.
2012 · Nikkei xTECH
The launch was covered as an "endpoint-agnostic voice-delay measurement solution."
2014 · Nikkei Trendy
A feature comparing 15 calling services drew on objective quality / R-value measurement.
2013 → · POLQA since 2013
POLQA-based from the start: objective evaluation aligned with international standards.
