Additional Notes:

• Selection Criteria: I focused on providers with dedicated compliance features for voice messaging, based on search results from sites like G2, Gartner, and provider websites. Results were filtered for those explicitly supporting high-volume use cases (e.g., handling 10,000+ messages per day).
• Trends and Considerations: As of 2025, demand for managed compliance in CPaaS has grown due to stricter global regulations. When evaluating these providers, consider factors like pricing, integration ease, and scalability. For example, Twilio and Vonage often lead in market share, but Sinch and Telnyx may offer more competitive pricing for startups.
• Limitations: This list is not exhaustive; other providers like Avaya or 8x8 might offer similar services but had less prominent search results for "managed compliance in high-volume voice." For the most up-to-date details, I recommend visiting the cited sources or performing a live search.
