AR Converter for Verizon One Talk
One Talk Automated Receptionist recordings have strict audio requirements — and most recording tools don't export in the right format by default. Drop your file in and we'll convert it automatically, no settings to configure.
Converts to the exact spec One Talk requires.
.wav
ulaw codec
8kHz sample rate
8-bit mono
Need the recording itself, not just the conversion? Professional AR recordings are part of every VoIP implementation we manage.
One Talk's Automated Receptionist uses the BroadWorks platform, which processes audio in G.711 μ-law (ulaw) encoding — the standard codec for North American telephone networks. Most recording tools export at 44.1kHz or 48kHz in PCM format. Uploading that file directly to One Talk will either fail silently or play back with distortion. The file must be re-encoded to 8kHz sample rate, 8-bit depth, mono channel, ulaw codec before upload.
Why does One Talk require this format?
FAQs
What audio format does Verizon One Talk require for auto attendant recordings?
One Talk's Automated Receptionist requires WAV files encoded with the μ-law (uLaw) codec, at 8kHz sample rate, 8-bit depth, mono channel. This is a telephony-standard format called G.711 μ-law, used by BroadWorks-based phone systems throughout North America. Most recording tools — including Voice Memos, Audacity, and ElevenLabs — do not export in this format by default.
Why won't my audio file upload to the One Talk portal?
The One Talk portal silently rejects audio files that don't match its required spec. Common culprits are files recorded at 44.1kHz or 48kHz (standard studio quality), stereo files instead of mono, MP3 or AAC files instead of WAV, and WAV files with the wrong codec (PCM instead of uLaw). Upload your file here and we'll convert it to the exact format One Talk accepts.
What's the difference between uLaw and A-Law?
Both are 8-bit logarithmic audio codecs used in telephone networks, but they're used in different regions. μ-law (uLaw) is the standard in North America and Japan. A-Law is used in Europe and most of the rest of the world. Verizon One Talk is a North American system and requires uLaw. Using A-Law will likely result in upload failure or distorted audio.
Can I use this converter for other phone systems?
Yes. The WAV uLaw 8kHz 8-bit mono format is required by many business phone systems beyond One Talk, including Cisco Unified Communications Manager, Asterisk, FreeSWITCH, RingCentral, and most BroadWorks-based platforms. If your system's documentation calls for CCITT μ-law, G.711, or 8kHz mono WAV, this converter will produce the right file.
What file types can I upload?
The converter accepts most common audio formats including MP3, WAV (any spec), M4A, AAC, OGG, FLAC, and AIFF. If you're exporting from a professional recording tool or AI voice platform like ElevenLabs, upload the file directly — no pre-processing needed.
Will converting to 8kHz make my recording sound worse?
Yes, and that's expected. The 8kHz sample rate limits audio to telephone-quality bandwidth (roughly 300Hz–3400Hz), which is intentional — it matches what phone networks actually transmit. A recording that sounds thin or low-fidelity on your computer will sound normal on a phone call. Start with the cleanest source recording you can produce, and the converted file will sound as good as possible within the format's constraints.
Do I need to install anything?
No. This is a browser-based tool — no software, no accounts, no settings to configure. Upload your file, download the converted WAV. The conversion happens automatically to the exact One Talk specification.
