(2) TCPA \u2014 opt-in capture, opt-out honored, recordkeeping for voice\/SMS. (3) State privacy laws (CCPA, VCDPA, CPA, others). (4) Encryption \u2014 TLS 1.3 in transit, AES-256 at rest.<\/p>\n<h2>Why This Matters for Brokers<\/h2>\n<p>Brokers face vicarious liability for any data breach involving client information. State real estate commissions audit data-handling. CFPB scrutinizes wire-fraud-related practices. Brokerages selecting AI TC software in 2026 are selecting their compliance posture.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>How does TCPA compliance work for AI voice agents?<\/h3>\n<p>The brokerage must capture documented consent before any automated voice or SMS contact. Consent must be specific to the channel and the party. Opt-out must be honored immediately and recorded. ReBillion captures consent at file open and respects opt-outs across files.<\/p>\n<h3>What is a sub-processor and why does it matter?<\/h3>\n<p>A sub-processor is a third party the vendor uses to process client data (e.g., Twilio for voice, AWS for hosting). GDPR requires disclosure and DPA pass-through. ReBillion publishes a sub-processor list and notifies before adding new ones.<\/p>\n<h3>How is wire-fraud risk mitigated by the security stack?<\/h3>\n<p>Verbal verification of wire instructions (workflow guardrail), encryption of all stored wire instructions, and audit trail of every email containing wire data. The security stack supports the workflow; it does not replace it.<\/p>\n<h3>Is ReBillion SOC 2 compliant?<\/h3>\n<p>SOC 2 is planned.<\/p>\n<h3>Does ReBillion publish security documentation?<\/h3>\n<p>Planned on the roadmap: a public sub-processor list, a public DPA template, and public privacy policy and TCPA disclosures.<\/p>\n<p><strong>Related reading:<\/strong> <a href=\"https:\/\/rebillion.ai\/blog\/tcpa-compliance-real-estate\/\">TCPA compliance guide<\/a>, <a href=\"https:\/\/rebillion.ai\/blog\/best-transaction-coordinator-software-2026\/\">Best TC software 2026<\/a>, <a href=\"https:\/\/rebillion.ai\/blog\/rebillion-sub-processor-list\/\">Sub-processor list<\/a>.<\/p>\n<p><script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"How does TCPA compliance work for AI voice agents?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The brokerage must capture documented consent before any automated voice or SMS contact.
