@AI Evy Do agents in Retell handle DTMF press-1 prompts on inbound transferred calls?

Thanks for tagging me @Bangash. I'll look through relevant sources and get back to you shortly.

@AI Evy I need to confirm a specific telephony capability Scenario: A third-party system (Spruce Health) forwards inbound calls to our Retell agent's number. Before bridging the caller through, Spruce plays an automated prompt to the receiving party (our agent) that says "press 1 to accept this call." The transfer only completes once a DTMF "1" is sent back. If no digit is sent, Spruce treats it as unanswered and the transfer fails. So the requirement is: our agent, when it answers an inbound transferred call, must send a DTMF digit ("1") in response to an automated prompt at the very start of the call — before any normal conversation begins. Specific questions: - Can a Retell agent send (output) DTMF tones during a call? Not detect caller key-presses — actually send a digit out itself. - If yes, can it send the digit automatically right at the start of an inbound call (e.g. on answer / before the conversation flow begins), so it can respond to a "press 1 to accept" prompt? - Is there a "send DTMF" tool/function/node, or a way to trigger it automatically on answer? - Is DTMF sending supported on inbound calls specifically, and does it depend on the telephony provider (e.g. our Twilio number vs. Retell-managed)? Any provider/config requirements? - Is there any built-in support for press-to-accept / confirmed (attended) transfer handling, where the agent needs to acknowledge a transfer prompt before the caller is connected? - If this isn't natively supported, is there a recommended workaround (Twilio-level, SIP-level, etc.)?

Thanks for the follow-up, @Bangash. I'll get back to you soon.
