Listen to User Keypad Input (DTMF Capture)

AI phone agents can sometimes struggle with capturing long numbers accurately due to background noise or unclear speech. Our new Listen to User Keypad Input feature allows callers to enter numbers using their keypad, improving accuracy.

How It Works:

• Set your AI agent to prompt users to enter digits (e.g., card number, phone number).
• The system captures input directly from the keypad—eliminating transcription errors.
• Use post-call analysis to store and process the data as needed.

Dynamic Routing

Need to route calls based on different customer requests? Try Dynamic Routing in call transfers.
Example:

• If the caller wants support, transfer to +1 (925) 222-2222
• If the caller wants sales, transfer to +1 (925) 333-3333

Set up call transfer logic to automatically direct calls to the right department.
