Where these files work
This output — PCM WAV, 48 kHz, 16-bit, mono — is a standard format for voice prompts, auto-attendant greetings, and music-on-hold on SIP phone systems. It's required by PortSIP and accepted by:
- PortSIP PBX — requires WAV PCM at 16 / 32 / 48 kHz, 16-bit, mono (48 kHz fully supported).
- 3CX — accepts uncompressed PCM WAV prompts in this format.
- FreeSWITCH / FusionPBX — natively handle 48 kHz, 16-bit, mono PCM WAV.
- Most SIP PBX & IVR platforms that accept uncompressed PCM WAV uploads.
Some legacy systems (e.g. Asterisk / FreePBX) expect 8 kHz audio — most resample automatically, but check your platform's prompt requirements if a file is rejected.
