### Answer Yes, a Retell AI inbound agent can press digits when it encounters an IVR system (like a robocaller asking to press a digit) . [(1) ]() The Press Digit tool is designed for agents to navigate IVR systems using DTMF input. When making phone calls, voice agents often encounter IVR (Interactive Voice Response) systems that require pressing digits on the phone keypad. To enable this capability: 1. Add a Press Digit Tool to your agent 2. Add navigation prompts with clear instructions on when and what digits to press 3. Add interaction rules for handling edge cases However, there's an important distinction: the Press Digit node is designed for the agent to navigate an IVR (press 1 for sales, etc.) — NOT for capturing user keypad input. [(2) ]() This means it's intended for scenarios where your agent needs to interact with external automated systems, not for collecting DTMF input from callers. For your specific use case of responding to a robocaller asking to press a digit, the Press Digit functionality should work, as it allows the agent to send DTMF tones in response to IVR prompts.

### Answer I don't have specific information about Philippine phone numbers in the available sources. However, Retell AI supports importing phone numbers from custom telephony providers via SIP trunking. [(1) ]() If you have a Philippine phone number from a telephony provider that supports elastic SIP trunking (like Twilio, Telnyx, or others) , you can import it to Retell using the Import Phone Number API. [(2) ]() [(1) ]() The import process requires: - The phone number in E.164 format (e.g., "+63XXXXXXXXXX" for Philippines) [(2) ]() - A termination URI from your SIP trunk provider - Optional authentication credentials if required by your provider For the most accurate information about Philippine number support and any specific requirements, I'd recommend checking out these potentially useful sources: [Custom Telephony Overview]() , [Import Phone Number]() . If you'd like, I could try to provide a general answer based on my knowledge instead.
