### Answer I don't have specific information about implementing holiday checks when transferring calls in the available sources. However, here are a couple of approaches you could consider: 1. Use a custom function before the transfer call tool to check if it's a holiday, and based on the result, either proceed with the transfer or handle it differently (e.g., play a message, route to voicemail) . 2. Use dynamic variables for the transfer destination — you could set the transfer number dynamically based on holiday logic handled in your backend via webhooks. [(1) ]() 3. Use the inbound call webhook to check holiday status before the call even engages the AI, and return an appropriate transfer destination or handling logic. [(2) ]() Check out these potentially useful sources: - [Transfer call]() - [Agent Transfer]() Would you like me to provide a general answer on how you might structure holiday checking logic with Retell's tools?
