Frequently Asked Questions
VOX is the native format for Dialogic telephony hardware. IVR and automated phone systems require VOX-encoded audio for prompts and greetings.
Dialogic boards, many IVR platforms, and legacy telephony systems consume VOX files directly for voice prompts and menu audio.
VOX uses 4-bit ADPCM at 8 kHz — a huge compression compared to 16-bit 44.1 kHz WAV. Files shrink by roughly 20 times.
No — 4-bit ADPCM at telephony sample rates is designed for speech intelligibility, not musical quality.
