India

India has one of the world’s most structured telecom compliance frameworks, administered by TRAI (Telecom Regulatory Authority of India) and DoT.

Area	Framework	Key requirement
Outbound voice — B2C	TRAI TCCCPR	140-series caller ID mandatory for all commercial outbound calls
Outbound voice — financial/govt	TRAI TCCCPR	1600-series for RBI/SEBI/IRDAI regulated entities
AI voice calls	TCCCPR Third Amendment (Sep 2026)	Declaration of AI-initiated calls to originating provider required
SMS — commercial	TRAI DLT	Entity, sender ID, and every template must be pre-registered
SMS — DND	NDNC registry	Promotional SMS to DND-registered numbers is blocked
Caller identity	CNAP	Calling Name Presentation via telecom operator database
Business verification	KYC	Required to provision Indian numbers on Vobiz

Quiet hours: Promotional calls and SMS — 9am to 9pm only. Transactional — any time. Violations: First instance — outgoing services barred 15 days. Repeat — all SIP/PRI resources disconnected across all providers for 1 year, with blacklisting.

United States

US compliance is governed by the FCC under the TCPA and the FTC for Do Not Call enforcement.

Area	Framework	Key requirement
Automated voice calls — marketing	TCPA	Prior express written consent required
AI voice calls	TCPA + 2024 FCC ruling	AI-generated voice requires written consent — same as pre-recorded robocall
Caller ID authentication	STIR/SHAKEN (TRACED Act)	All US carriers must sign and verify caller ID cryptographically
DNC compliance	FTC National DNC Registry	Scrub all contacts before outbound campaigns
SMS — A2P	A2P 10DLC	Brand + campaign registration with The Campaign Registry required
SMS — consent	TCPA	Written consent for marketing SMS; express consent for transactional
SMS — opt-out	CTIA guidelines + TCPA	STOP keywords must be honoured immediately

Quiet hours: 8am to 9pm in the recipient’s local time zone — voice and SMS. Penalties: $500–$1,500 per violation (per call or text). Private right of action — class actions common. No de minimis threshold. TCPA applies to any sender calling US numbers — location of the business is irrelevant.

European Union

The EU’s voice and SMS compliance landscape is shaped by GDPR and the ePrivacy Directive.

Area	Framework	Key requirement
Marketing calls	ePrivacy Directive	Explicit consent or legitimate interest (varies by member state)
Automated calls / robocalls	National implementations	Most EU member states prohibit automated marketing calls without prior consent
SMS marketing	ePrivacy Directive + national law	Opt-in consent required in most member states
Data handling	GDPR	Contact data processing requires a lawful basis; right to erasure applies to suppression lists
Caller ID	National regulation	Most EU states require accurate CLI presentation; anonymised calling is restricted
AI-generated voice	EU AI Act (2024)	High-risk AI systems must be disclosed; synthetic voice must be labelled in certain contexts

Key variation: ePrivacy rules are implemented differently by each member state. Germany, France, and Spain have stricter rules than the baseline Directive. Always confirm the specific rules for each country you call. Quiet hours: Vary by member state — typically no calls before 9am or after 8pm on weekdays; more restrictive on weekends.

United Kingdom

Post-Brexit, the UK operates its own framework based on the Privacy and Electronic Communications Regulations (PECR) and UK GDPR.

Area	Framework	Key requirement
Marketing calls	PECR	Soft opt-in for existing customers; explicit consent for new contacts
Automated calls	PECR	Prior explicit consent required for all automated marketing calls
SMS marketing	PECR	Prior explicit consent required
Caller ID	Ofcom rules	CLI must be presented accurately; withheld number restrictions
DNC	TPS / CTPS	Telephone Preference Service — equivalent to US DNC Registry
Data handling	UK GDPR	Equivalent to EU GDPR post-Brexit

SMS — KSA	CITC	Arabic sender IDs for Saudi recipients; template pre-registration required

Global principles for AI voice agent compliance

Across all markets, AI voice agent deployments that make outbound calls to consumers must address: 1. Consent: Most jurisdictions require some form of consent before automated or AI-generated calls. The standard ranges from implied consent (some EU markets for existing customers) to written consent (US, for all AI calls). 2. Identification: The AI must not impersonate a human in jurisdictions with disclosure requirements. The EU AI Act and emerging US state laws (California, Colorado) require disclosure that the caller is an AI in certain contexts. 3. Opt-out: Every market requires a mechanism to opt out of further contact. Honour opt-outs immediately and maintain suppression lists indefinitely. 4. Record-keeping: Maintain records of consent, campaign parameters, and delivery outcomes. These are your defence in a regulatory dispute. 5. Data residency: Recorded calls and transcripts may be subject to data residency requirements in India (must stay in India), EU (GDPR transfer rules), and other markets.
