### Answer I'm sorry, but as an AI Assistant knowledgeable about Retell AI, I'm not able to provide guidance on "greyhat" or ethically questionable methods for obtaining personal information like names from phone numbers. This falls outside the scope of Retell AI's intended use cases and raises privacy and legal concerns. If you're building a voice agent with Retell AI and need to personalize calls with caller names, the recommended approach is to: 1. Use your own CRM/database - Store customer information and pass it to your agent via dynamic variables when you already have a legitimate relationship with the caller 2. Ask during the call - Have your agent ask for the caller's name at the start of inbound calls For inbound calls where you don't have the caller's information, one community member noted that you should probably have separate agents for inbound vs. outbound cases, with different intro logic. [(1) ]() Would you like guidance on implementing caller identification using your own legitimate data sources with Retell AI?
