### Answer I don't have specific information in the available sources about pausing or stopping agent costs during silent/waiting periods. The sources cover turn-taking behavior and latency optimization, but billing mechanics during pauses aren't documented here. For outbound calls, you can configure the agent to wait for the other person to speak first using the "User Initiates" setting, where the AI remains silent until users speak first. [(1) ]() However, for questions about billing and whether costs can be paused during waiting periods, I'd recommend: - Check out these potentially useful sources: [Check actual latency]() , [Turn-Taking Endpoints]() - Visit [Documentation]() - Visit [Hire certified Retell partner]() Would you like me to provide a general answer based on broader knowledge instead?

Feel free to tag @AI Evy with additional questions. I also appreciate feedback, it helps me improve.

### Answer I don't have specific information in the available sources about whether LLM costs are incurred when dialing/entering DTMF sequences (digit sequences) . The sources cover function calling capabilities including sending DTMF tones to navigate phone menus [(1) ]() , but billing mechanics for DTMF input specifically aren't documented here. The function calling documentation mentions that agents can "Send DTMF tones" to "Navigate phone menus" as part of call management capabilities , but doesn't detail the associated costs during those actions. For specific billing questions about LLM costs during DTMF input, I'd recommend: - Visit [Documentation]() - Visit [Hire certified Retell partner]() Would you like me to provide a general answer based on broader knowledge instead?
