Join the companies already turning everyday conversations into certified legal proof
Why your company needs registered call recording
When a dispute hits, proving what was actually said, and when, changes everything. Here's what registered call recording gets you.
Legal certainty
Irrefutable proof of what was agreed, and exactly when, valid before any authority that asks for it.
Tamper-proof by design
SHA-256 hashing on the audio and transcript means nothing can be altered after the fact without leaving a trace.
Fewer disputes
An objective record of what was actually said heads off conflicts with employees, customers, and suppliers before they escalate.
Built for compliance
Hand the certificate straight to auditors, labor inspectors, mediators, arbitrators, or a courtroom.
Better calls, too
Reviewing conversations doesn't just protect you legally, it surfaces where your team can sharpen customer service.
Zero disruption
Certify what you're already recording, on the infrastructure you already have. No rerouted calls, no new phone system, just an API that plugs straight in.
Not sure how this fits your setup?
Let's talk it through
When should you use a registered call?
Use cases
Registered calls help you prove the conversations your company already handles every day, without changing how you work.
Verbal consent
Capture consent and verification by voice, with evidence to back it up.
Phone-based contracts
Deals closed by phone get the same legal weight as a signed contract, fully compliant with data and consumer protection rules.
Mediation and arbitration
Solid evidence for ADR processes, resolving disputes faster and often before they reach a courtroom.
Complaints and quality control
Settle disagreements with customers or suppliers on the spot, with an indisputable record of what was actually said.
Sensitive conversations
Give HR and compliance calls the traceability and integrity that protect both the company and its people.
Questions about Registered call ?
Here's what you need to know.
What is a Registered Call?
Think of it as legal-grade proof for a phone conversation. Lleida.net captures the call — or any voice file , along with its transcript, then locks it under a legal guarantee seal that holds up to scrutiny from third parties. The payoff: a simple recording becomes registered evidence you can actually use in court, a claim, an audit, or any situation where you need to prove what was said and when.
Can I legally record a phone call in Spain?
Yes, as long as you're one of the people on the call. Spanish law treats this as valid evidence, provided the recording hasn't been altered or obtained in violation of someone's fundamental rights. Spain's Supreme Court has settled this more than once: if you're part of the conversation, you don't have to tell the other person you're recording , that's not a breach of communications privacy. One catch: companies recording calls for contractual purposes have to disclose how they handle that data, as required by the GDPR and Spain's data protection law.
What if I want to record without the other person's consent?
That only works if you're actually on the call yourself. Record someone else's conversation without permission, and you're looking at a criminal offense in Spain (Article 197 of the Criminal Code), prison time and fines included.
How do I get a mobile-recorded call registered?
Send us the audio file and its transcript through our API, that's it. We handle the rest and hand you back a certificate of evidence with full legal validity.
Isn't recording a call the same as registering it?
Not quite. Recording just gets you the audio. Registering is what gives it legal teeth: a trusted provider like Lleida.net processes the file, applies a timestamp, generates a unique integrity (hash), and stores everything securely. That's the difference between a recording nobody can vouch for and one that counts as evidence.
How do I know if a registered recording has been tampered with?
Every certificate carries a unique hash generated the moment it's registered, plus other built-in integrity checks. Alter so much as a single byte of the file, and the hash changes completely , tampering can't hide.
Will I need to switch phone providers or systems?
No.All we need is the audio file and transcript. We don't touch your telephony setup or reroute a single call. Keep using whatever provider and systems you're on now.
What audio formats work?
Nearly all of them, including the common ones, MP3, WAV, M4A. Not sure about yours? Just ask our team before you start.
Does a Registered Call hold up in mediation or arbitration?
Yes.If a dispute is headed toward mediation, conciliation, or arbitration instead of court, a Registered Call gives you solid, verifiable proof of exactly what was agreed.
