Architecting Regulatory Compliant Dialing Strategies for TCPA and Ofcom Jurisdictions
What This Guide Covers
You will build a resilient outbound dialing architecture in Genesys Cloud CX that enforces strict TCPA (USA) and Ofcom (UK) compliance through dynamic do-not-call (DNC) list management, time-zone aware scheduling, and granular consent tracking. The end result is a dialing strategy that automatically suppresses ineligible numbers, respects local call-time windows based on the recipient’s geographic location, and generates an immutable audit trail for regulatory inspection.
Prerequisites, Roles & Licensing
- Licensing: Genesys Cloud CX 1 or CX 2 license with the Workforce Engage add-on. Predictive and Progressive dialing modes require Workforce Engage.
- Permissions:
Data > Data Connector > Edit(to configure DNC connectors)Telephony > Outbound Dialing > Edit(to configure DNC lists and dialing rules)Architect > Architect Flow > Edit(to build the dialing logic)
- OAuth Scopes: If managing DNC lists via API, you need
dnc:readanddnc:write. - External Dependencies:
- A reliable Time Zone database or geolocation service to map phone numbers to local times.
- An upstream CRM or Consent Management Platform (CMP) that pushes consent records to Genesys Cloud.
The Implementation Deep-Dive
1. Constructing the Hierarchical Do-Not-Call (DNC) Architecture
Regulatory compliance begins with data suppression. The trap here is treating DNC as a single flat list. TCPA requires national and state-specific lists, while Ofcom requires adherence to the Telephone Preference Service (TPS). A flat list cannot handle the nuance of “Opt-in” overrides versus “Opt-out” mandates without complex conditional logic that fails under load.
We implement a hierarchical DNC structure using Genesys Cloud’s native DNC engine. This allows us to layer suppression rules: National > State/Regional > Enterprise > Campaign.
Step 1: Configure the DNC Connector
You must ingest your external consent data into Genesys Cloud. We use a Data Connector to stream consent records from your CRM into the DNC table.
- Navigate to Admin > Data > Connectors.
- Create a new connector targeting your CRM (e.g., Salesforce).
- Map the source fields to Genesys Cloud DNC fields:
Phone Number→dnc_numberConsent Type→dnc_type(CRITICAL: Distinguish betweenNATIONAL,STATE,TPS, andENTERPRISE).Consent Date→dnc_date
Step 2: Define DNC Lists and Hierarchy
Do not rely on the default DNC list alone. Create specific lists for each jurisdiction.
- Go to Admin > Telephony > Outbound Dialing > DNC Lists.
- Create the following lists:
US_NATIONAL_DNC: Contains numbers from the US National DNC registry.US_STATE_DNC: Contains numbers from state-specific registries (e.g., Florida, California).UK_TPS_DNC: Contains numbers registered with the UK Telephone Preference Service.ENTERPRISE_OPT_OUT: Contains customers who have explicitly opted out of your communications.
The Trap: The “Hard Block” Misconfiguration
A common error is setting the DNC action to “Block” for all lists. If a customer has a valid, recent consent record in your CRM that overrides a national DNC registration (permitted under specific TCPA exemptions for existing business relationships), a hard block prevents the call from ever initiating. This leads to false positives and lost revenue.
The Architectural Fix:
Use the “Check and Log” action for national/state lists and “Block” only for enterprise opt-outs. In the flow, you will explicitly check for a consent override before applying the block. This preserves the audit trail while allowing compliant calls to proceed.
2. Implementing Time-Zone Aware Dialing Windows
TCPA restricts calls to 8 AM – 9 PM local time. Ofcom restricts calls to 8 AM – 9 PM local time. The trap is using the agent’s time zone or the server’s time zone. You must determine the recipient’s local time at the moment of dialing.
Genesys Cloud does not automatically geolocate phone numbers for time-zone purposes in the dialing rules. We must inject this logic into the Architect flow.
Step 1: Geolocation Lookup
Before the dialing block, you must resolve the phone number to a time zone.
- In Architect, add a Web Service block.
- Configure the web service to call a geolocation API (e.g., Twilio Lookup, NumVerify, or a custom internal service).
- Input:
{{interaction.contact_attributes.phone_number}} - Output: Extract the
time_zonefield (e.g.,America/New_York,Europe/London). - Set the output variable to
{{contact.local_tz}}.
The Trap: Cache Staleness
If you cache geolocation results in the contact attributes for too long, a customer who moves from California to New York will be called at 7 AM Pacific (10 AM Eastern), which is compliant, or 10 PM Pacific (1 AM Eastern), which is a violation.
The Architectural Fix:
Use a short-lived cache or perform the lookup on every dial attempt if using Predictive dialing. For Progressive/Power dialing, where the agent is already engaged, the overhead is negligible. Set the web service timeout to 2 seconds to prevent dialing latency.
Step 2: Time Window Validation
Add an Expression block after the geolocation lookup.
- Expression:
// Convert current UTC time to recipient's local time let localTime = now().setTimezone(contact.local_tz); let hour = localTime.hour(); let minute = localTime.minute(); // TCPA/Ofcom: 8:00 AM to 9:00 PM (21:00) // Note: 9 PM is inclusive in some interpretations, but 8:00 PM 59:59 is safer. let isWithinWindow = (hour >= 8 && hour < 21); return isWithinWindow; - Outcome: If
true, proceed to dial. Iffalse, route to a “Schedule Retry” queue or drop the call with a specific disposition codeTIME_WINDOW_VIOLATION.
3. Configuring Outbound Dialing Rules and Consent Overrides
Now we combine DNC and Time Zone logic into the Outbound Dialing Strategy.
Step 1: Create the Dialing Strategy
- Navigate to Admin > Telephony > Outbound Dialing > Dialing Strategies.
- Create a new strategy named
TCPA_Ofcom_Compliant_Progressive. - Dialing Mode: Set to
ProgressiveorPredictivebased on your agent capacity. - DNC Settings:
- Check Use DNC.
- Select the
US_NATIONAL_DNC,US_STATE_DNC,UK_TPS_DNC, andENTERPRISE_OPT_OUTlists. - Action: Set to
BlockforENTERPRISE_OPT_OUT. Set toCheckfor others. - Note: The “Check” action allows the flow to handle the override logic, whereas “Block” stops the call immediately at the dialing engine level.
Step 2: Architect Flow Integration
The dialing strategy feeds into an Architect flow. The flow must handle the “Check” results.
- Start Block → Outbound Dialing Block.
- In the Outbound Dialing block, select the
TCPA_Ofcom_Compliant_Progressivestrategy. - Add a Decision Block after the Outbound Dialing block to check the
dnc_statusattribute.- Condition:
{{contact.dnc_status}}equalsBLOCKED. - If True: Route to Disposition block with code
DNC_BLOCKED. - If False: Proceed to Geolocation Lookup (Step 2 above).
- Condition:
The Trap: Ignoring State-Specific Exemptions
Some US states (e.g., Texas, Florida) have stricter rules than the federal TCPA. For example, some states prohibit calling numbers on the National DNC list even if the customer has an existing business relationship. Your US_STATE_DNC list must be treated with higher priority than the US_NATIONAL_DNC list.
The Architectural Fix:
In your Data Connector, ensure that state-specific DNC records have a higher priority weight or are merged into a single STATE_DNC list that is checked before the national list. If a number is on any state list, it must be blocked unless an explicit, documented enterprise opt-in exists.
4. Immutable Audit Trail and Disposition Mapping
Regulators require proof of compliance. You must log every decision: why a call was made, why it was blocked, and what consent was verified.
Step 1: Custom Attributes for Audit
Create custom attributes on the Interaction to store compliance data.
- Go to Admin > Custom Objects > Interaction.
- Add fields:
compliance_dnc_list_hit: Text (e.g., “US_NATIONAL”, “UK_TPS”)compliance_tz_check: Booleancompliance_consent_source: Text (e.g., “CRM_2023-10-01”)
Step 2: Populating Attributes in Architect
In the Architect flow, before the dialing block, use a Set Attribute block.
compliance_tz_check:truecompliance_consent_source:{{contact.consent_record_id}}
If the call is blocked by DNC:
compliance_dnc_list_hit:{{contact.dnc_list_name}}
Step 3: Disposition Codes
Ensure your Disposition Codes are mapped to regulatory outcomes.
- Go to Admin > Telephony > Outbound Dialing > Disposition Codes.
- Create codes:
TCPA_DNC_BLOCKTCPA_TIME_WINDOW_BLOCKOFCOM_TPS_BLOCK
- Map these codes to the “Blocked” outcome in the Outbound Dialing strategy.
The Trap: Manual Disposition Overwrites
Agents can manually change dispositions after a call. If an agent changes TCPA_DNC_BLOCK to NO_ANSWER, the audit trail is corrupted.
The Architectural Fix:
Lock disposition codes for blocked calls. In the Architect flow, if the call is blocked by DNC or Time Zone, do not route to an agent. Route directly to a Disposition block that sets the code and ends the interaction. This prevents agent interference. For calls that connect, use Interaction Attributes to lock the compliance-related fields so they cannot be edited post-call.
Validation, Edge Cases & Troubleshooting
Edge Case 1: The “Roaming” Recipient
The Failure Condition:
A customer registered in the UK (Ofcom jurisdiction) is traveling in the USA. Their number is not on the TPS list, but they are in a US time zone. You dial them at 10 PM UK time, which is 5 PM US time. Is this compliant?
The Root Cause:
Regulations are typically tied to the number’s jurisdiction, not the recipient’s physical location. TCPA applies to numbers with US area codes. Ofcom applies to numbers with UK area codes. The geolocation lookup returns the time zone of the number’s registration, not the recipient’s current GPS location.
The Solution:
Always use the time zone associated with the phone number’s country code and area code, not the recipient’s real-time location. Your geolocation API should return the “Default Time Zone” for that number prefix. Do not attempt to track real-time location for compliance; it is technically unfeasible and legally ambiguous.
Edge Case 2: The “Opt-In” Lag
The Failure Condition:
A customer opts in via your website at 9:00 AM. The data connector syncs to Genesys Cloud at 9:30 AM. A call is scheduled at 9:15 AM. The call is blocked because the consent record is not yet in Genesys Cloud.
The Root Cause:
Batch data connectors have latency. Real-time compliance requires real-time data.
The Solution:
Implement a real-time API check in the Architect flow.
- Before the DNC check, add a Web Service block that calls your CRM’s API to check for recent opt-ins (last 24 hours).
- If the CRM returns a valid opt-in, set a flag
{{contact.real_time_opt_in}} = true. - In the DNC Decision block, add an override: If
{{contact.real_time_opt_in}}istrueAND the DNC hit isENTERPRISE_OPT_OUT, allow the call. - Note: This does not override National/State DNC lists. It only overrides your internal opt-out list.
Edge Case 3: The “Predictive” Abandonment Rate
The Failure Condition:
You use Predictive dialing. The system dials 100 numbers, expecting 10 agents to be free. 50 numbers are blocked by DNC or Time Zone rules after the dialing engine has already initiated the SIP INVITE. The call connects, then is immediately dropped. This counts as an “Abandoned Call” and skews your abandonment rate metrics, potentially violating FCC abandonment rules (3% max).
The Root Cause:
The DNC and Time Zone checks are happening in the Architect flow after the Outbound Dialing block has already placed the call.
The Solution:
Move all compliance checks to the Outbound Dialing Strategy level, not the Architect flow.
- In the Dialing Strategy, use the Pre-Dial Validation feature (if available in your Genesys version) or configure the DNC lists to “Block” at the strategy level.
- For Time Zone checks, you cannot do this at the strategy level natively. You must use a Campaign with a Dialing Rule that filters contacts based on a pre-calculated attribute.
- Best Practice: Pre-filter your contact lists. Before loading contacts into the Outbound Campaign, run a batch process that evaluates DNC and Time Zone rules. Only load contacts that pass both checks into the campaign. This ensures the dialing engine only dials compliant numbers.
