In short

Call center recordings pair real customer problems with how skilled agents resolve them, which voice agents need to learn.
Payment card numbers and other sensitive details spoken on calls must be removed before any audio is shared.
Customers were told calls may be recorded, but what they were told about later use decides how the audio can be licensed.
Transcripts with outcomes, such as resolution or sale, are worth more than audio on its own.

Why voice agent builders want call recordings

A voice agent has to handle interruptions, accents, background noise, angry customers and identity checks. Call center recordings capture all of this, together with how a trained agent responded. Outcome codes (resolved, escalated, sale, cancellation) let a buyer train on what worked.

Many US states require only one party's consent to record a call, but several require all parties to consent. Your recording disclosure ("this call may be recorded for quality and training purposes") is usually the starting point for what you can do with the audio. Whether "training" in that message extends to training third-party AI models is a legal question your counsel should answer for your specific wording and jurisdictions.

Outsourced contact centers

If you run calls for clients, the recordings usually belong to the client or are controlled by the client contract. Outsourcers can only license recordings with each client's written consent.

Redaction

Spoken card numbers, bank details, Social Security numbers and health information must be removed from both audio (by muting or tone replacement) and transcripts. Many call platforms already pause recording during payment, but older archives may not.

A practical approach

Start by licensing transcripts that have been de-identified, which carries less risk than audio. Add audio for calls where consent and redaction are confirmed.

Questions

Does 'calls may be recorded for training' cover AI training?

Not necessarily. It may have been understood as staff training. Ask your counsel to review the exact wording and the privacy notice in force when calls were recorded.

Can an outsourced call center sell client calls?

Only with each client's written consent, because the recordings are normally the client's data under the services contract.

Do buyers want transcripts or audio?

Speech and voice agent buyers want both. Text-only buyers will take de-identified transcripts, which is often the easier first deal.
