Terms of Service

1. Acceptance of These Terms

By creating an account, generating or using an API key, accessing the Site, or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services. If you are accepting on behalf of a company or other legal entity, you represent that you have authority to bind that entity.

2. The Services

• What we provide: Revox provides a hosted API for managing, initiating, and monitoring AI voice calls and communications over HTTPS with bearer-token authentication (API keys).
• Authentication: All endpoints require bearer-token authentication. You are responsible for keeping API keys secure and for all activity under your account.
• Updates: We may modify the Services (including adding or removing features) or update documentation as needed. Material changes will be communicated with at least 14 days' notice.

3. Fees, Billing, and Taxes

4. Telephony Compliance — Outbound Calls

This section governs all outbound voice calls initiated through the Services, whether using Revox-provisioned phone numbers or your own numbers ("Customer Numbers"). Revox operates as a technology infrastructure provider only. All regulatory obligations for the calls you initiate rest solely and exclusively with you.

4.1 Regulatory Acknowledgement

You acknowledge and agree that:

• AI-generated voice calls are classified as "artificial or prerecorded voice" under the U.S. Telephone Consumer Protection Act (TCPA) (FCC Declaratory Ruling, February 2024) and equivalent legislation in other jurisdictions.
• Under French law (Code des postes et des communications électroniques and the blocking list regime effective 1 August 2026 under Décret n°2024-1223), outbound prospecting calls to consumers registered on the Bloctel list are prohibited. Calls made under a legitimate pre-existing contractual relationship are permitted, subject to the conditions set out in Article L34-5 CPCE.
• EU AI Act Article 50 (effective August 2026) requires that any AI system interacting with humans via voice must disclose its artificial nature at the outset of the interaction, unless the context makes it obvious.
• Additional state-level and country-level laws may apply depending on the jurisdiction of the called party (e.g., Florida Telephone Solicitation Act, California CCPA/CPRA, Germany UWG §7, etc.).

4.2 Mandatory Consent Requirements

You represent and warrant that, before initiating any outbound call through the Services:

• You have obtained the level of consent required by applicable law for the type of call being made:
  • Marketing/commercial prospecting calls: Prior Express Written Consent (PEWC) or equivalent opt-in consent under applicable national law.
  • Non-marketing operational calls (e.g., appointment reminders, KYC callbacks, onboarding, collections under an existing relationship): Prior Express Consent (PEC) or equivalent.
• Where required by law, consent specifically authorises the use of an AI-generated or automated voice.
• You maintain a documented record of each consent, including the date, method, and scope of consent obtained.
• Consent records are retained for a minimum of five (5) years from the date of the last call made on the basis of that consent, or such longer period as required by applicable law.
• You provide a clear, accessible, and functional opt-out mechanism in every outbound call and honour opt-out requests immediately.

4.3 AI Voice Disclosure

You must programme your voice agent to disclose at the commencement of every outbound call, and prior to collecting any personal data from the called party, that the caller is an AI voice agent. Disclosure must be:

• Clear and unambiguous — it must not be buried in post-greeting disclosures or delivered in a way that could be missed.
• Provided in the language of the call.
• Compliant with any jurisdiction-specific wording requirements (e.g., California law currently requires the caller to identify itself as "automated"; EU AI Act requires disclosure that the interaction is with an AI system).

4.4 Do-Not-Call (DNC) Compliance

• You must scrub all call lists against applicable national, state, and customer-specific Do-Not-Call registries before launching any campaign.
• Scrubbing must occur no less frequently than every thirty-one (31) days for ongoing campaigns.
• For France, all consumer numbers must be checked against the Bloctel registry (www.bloctel.gouv.fr) no less than every thirty (30) days.
• You must maintain and honour an internal DNC list for contacts who have requested not to be called, with immediate effect from the date of the opt-out request.
• B2B calls to business direct lines may be exempt from national DNC registries in certain jurisdictions, but you remain responsible for verifying the applicable exemption.

4.5 Calling Hours and Dialling Limits

You must comply with permitted calling hours in the jurisdiction of the called party. As a default minimum:

• United States: 8:00 AM – 9:00 PM local time of the called party (TCPA / TSR).
• France / EU: 9:00 AM – 7:00 PM local time on weekdays; calls are prohibited on Sundays and public holidays under Décret n°2024-1223.
• Other jurisdictions: the most restrictive applicable hours under national law.

You are responsible for configuring time-zone-aware dialling logic within your integration.

4.6 STIR/SHAKEN and Caller Identity

For calls originating on Revox-provisioned numbers, Revox will use commercially reasonable efforts to support STIR/SHAKEN attestation at the level available given the carrier chain. For Customer Numbers used via BYOC (Section 6), STIR/SHAKEN attestation level is determined by your carrier and SIP trunk configuration. You are solely responsible for:

• Registering and maintaining any required business profiles with your carrier.
• Ensuring that the Caller ID presented on outbound calls is accurate, not spoofed, and reflects a number you are authorised to use.
• Complying with FCC rules and equivalent national regulations prohibiting caller ID spoofing.

5. Call Recording, Transcripts, and Data Protection

5.1 Default Settings

Call recording and transcription are enabled by default. You may adjust these settings via the API or dashboard, subject to the retention policy set out below.

5.2 Your Obligations

• You are responsible for providing legally required notices and obtaining required consents for call recording from all call participants, including under applicable wiretapping, e-privacy, and consumer protection laws.
• In jurisdictions requiring two-party or all-party consent for recording (e.g., California, Germany, France under Article L226-1 of the Code pénal), you must obtain such consent before the call is recorded.
• You must not use transcripts or recordings for purposes incompatible with those disclosed to the called party at the time of consent.

5.3 Data Protection

To the extent personal data is processed in connection with the Services, the parties will comply with applicable data protection laws, including the EU General Data Protection Regulation (GDPR). A Data Processing Addendum (DPA) is available and, where required by law, will be executed between the parties. Revox acts as a data processor in respect of personal data contained in call content; you act as the data controller.

6. Phone Numbers and Bring Your Own Number (BYOC)

6.1 Revox-Provisioned Numbers — Included Up to 1,000 Outbound Calls per Month

• The 1,000 call limit is a hard platform limit enforced at the API level. Once reached, outbound calls using Revox-provisioned numbers will be rejected with an error code until the next calendar month.
• To continue making outbound calls beyond 1,000 per month, you must connect your own phone number ("BYOC") as set out in Section 6.2 below.
• The limit applies per organisation account across all Revox-provisioned numbers assigned to that account.
• Inbound calls received on Revox-provisioned numbers are not counted toward the monthly limit.
• Revox-provisioned numbers are not available on free trial accounts. A paid subscription is required.

6.2 Bring Your Own Number (BYOC) — Required Above 1,000 Calls per Month

Customers requiring more than 1,000 outbound calls per calendar month must connect their own phone numbers or SIP trunks to the Services ("Customer Numbers"). BYOC is available on all paid plans at no additional platform fee. Standard per-minute usage charges continue to apply.

To use BYOC, you must:

• Own or be expressly authorised to use each Customer Number by the incumbent carrier or number assignee.
• Have completed all carrier-side regulatory compliance requirements for the originating country (e.g., French ARCEP number registration, Twilio Regulatory Bundle approval, Telnyx regulatory submissions for EU local numbers).
• Have verified your identity with Revox in accordance with our onboarding requirements.
• Have an active paid Revox subscription.

6.3 Customer Responsibility for BYOC Numbers

When using BYOC, you retain full responsibility for:

• All telephony costs charged by your carrier (origination, termination, number rental, DID fees).
• Number portability, porting-out, and number validity. Revox is not responsible for call failures arising from carrier-side configuration errors.
• STIR/SHAKEN attestation level — Revox cannot guarantee attestation level for Customer Numbers; this is determined by your carrier chain.
• Compliance with all obligations in Section 4 (Telephony Compliance). The use of your own numbers does not alter or reduce your regulatory obligations in any way.
• Ensuring Customer Numbers are not used for any purpose that violates these Terms or applicable law, including the prohibitions in Section 8 (Acceptable Use).

6.4 Technical Requirements for BYOC

BYOC integration is supported via:

• Elastic SIP Trunking (recommended): Configure your SIP trunk to point to Revox's SIP endpoint. Supported providers include Twilio, Telnyx, and Vonage.
• Dial-to-SIP-URI: Supported for complex or non-elastic telephony environments. Note that native Revox call-transfer features may not be available with this method.

Revox does not support direct connection of standard carrier mobile or landline numbers that do not permit SIP trunking.

7. Your Content

"Your Content" includes data, prompts, call scripts, audio, transcripts, metadata, and any content you send to or generate through the Services. You represent that you hold the rights to provide Your Content and to instruct Revox to process it. You grant Revox a limited licence to process Your Content solely to provide the Services.

8. Acceptable Use

You agree not to use the Services to:

• Make calls to any party who has not provided the consent required by applicable law, including to numbers on a DNC registry for which no valid exemption applies.
• Transmit false, misleading, or deceptive Caller ID information (caller ID spoofing).
• Conduct calls in violation of applicable calling-hours restrictions.
• Fail to disclose at the outset of a call that the caller is an AI voice agent, where required by law.
• Engage in harassment, threats, abusive language, or any conduct that could constitute a criminal offence.
• Make robocalls or spam calls as defined under TCPA, TSR, GDPR, CNIL guidance, or equivalent national laws.
• Operate any pyramid scheme, Ponzi scheme, make-money-fast scheme, phishing, or fraudulent promotion.
• Reverse engineer, decompile, or attempt to extract source code from the Services.
• Use the Services to build a product that directly competes with Revox using the Services' outputs.
• Circumvent the 1,000 outbound call limit on Revox-provisioned numbers through technical workarounds (e.g., creating multiple accounts to exceed the monthly cap).
• Use the Services in connection with regulated use cases (healthcare, financial advice, legal advice, minors' services) without ensuring compliance with all sector-specific regulations.

9. Audit Rights and Monitoring

Revox reserves the right to:

• Monitor aggregate call patterns and metadata (not call content) to detect potential compliance violations, abuse, or anomalous usage.
• Request documentary evidence of consent records, DNC scrubbing logs, and use-case descriptions. You must provide such evidence within ten (10) business days of a written request.
• Suspend access to the Services without prior notice if Revox reasonably believes that your use poses an imminent regulatory, legal, or reputational risk to Revox or to third parties, pending investigation.
• Terminate the Agreement if you fail to remedy a compliance breach within thirty (30) days of written notice (or immediately if the breach is irremediable).

10. Confidentiality

Each party must protect the other party's Confidential Information using at least reasonable care and may use it only as permitted by these Terms. Confidential Information does not include information that is publicly known, independently developed, or received from a third party without restriction.

11. Term and Termination

These Terms begin when you first use the Services and continue until terminated. Either party may terminate for convenience with thirty (30) days' written notice. We may suspend or terminate access immediately if you materially breach these Terms (in particular Section 4, Section 6, or Section 8), if required by law, or if your use poses risk of harm to the Services or to third parties. Upon termination, your right to use the Services ceases. Sections 4, 7, 9, 12, 13, and 14 survive termination.

12. Warranties and Liability

12.1 Disclaimer

The Services are provided "as is" and "as available." Revox does not warrant uninterrupted or error-free operation, nor that the Services will meet any specific regulatory requirement applicable to your use case.

12.2 Limitation of Liability

Neither party will be liable for indirect, consequential, special, or punitive damages, including loss of revenue, loss of data, or loss of goodwill. Each party's total cumulative liability is capped at the fees paid or payable by you in the twelve (12) months preceding the event giving rise to the claim.

The limitation on liability does not apply to: (i) your indemnification obligations; (ii) breach of Section 4, Section 6, or Section 8; (iii) wilful misconduct or gross negligence; or (iv) death or personal injury caused by negligence.

13. Indemnification

You will indemnify, defend, and hold harmless Revox and its officers, directors, employees, and agents from and against any and all claims, damages, fines, penalties, costs, and expenses (including reasonable legal fees) arising from or related to:

• Your use of the Services, including all outbound calls initiated through the Services.
• Any violation of applicable law, including TCPA, TSR, GDPR, French e-privacy law, EU AI Act, or equivalent national legislation.
• Any claim by a called party arising from calls you initiated, including claims of unwanted calls, lack of consent, or failure to disclose AI voice usage.
• Your Content or your instructions to the Services.
• Your violation of these Terms, including the Acceptable Use Policy.

Revox will indemnify you for third-party claims alleging that the Services (as provided by Revox, unmodified) infringe third-party intellectual property rights, subject to standard exclusions (modification, combination with third-party materials, use contrary to documentation).

14. Governing Law and Jurisdiction

These Terms are governed by French law, excluding conflict-of-law rules. Disputes shall be submitted to the exclusive jurisdiction of the competent courts of Paris, France, except where mandatory consumer protection law requires otherwise.
