### Answer The

dialKeypadFunctionEnabled

flag allows an assistant to dial digits on a keypad during a phone call, which is essential for navigating through phone menus or automated systems. To utilize this functionality, you need to enable it in the assistant settings when creating or updating an assistant. Here's a brief example of how you might set this up in your API call:

json
{
  "dialKeypadFunctionEnabled": true
}

[(1)]() Once this feature is enabled, your assistant can interact with phone systems that require DTMF (Dual-Tone Multi-Frequency) inputs. However, the specific implementation details—like how to instruct the assistant to dial a sequence during a call—might depend on additional scripting or configuration in your assistant's logic. For more detailed guidance and examples on setting up your assistant with this capability, you can refer back to the Vapi documentation on assistant creation or updating where this feature is described . If you need further customization or encounter any specific issues, the documentation also covers creating custom functions that might be used to extend the capabilities of your assistant . Feel free to explore these parts of the documentation to better integrate and utilize the

dialKeypadFunctionEnabled

feature.

Got it. Tagging @User for additional help.

This doesn't seem to work with anything but OpenAI models. I've tested with Groq using Mixtral 8x7b and Llama3 70b which both support function calling. But the DTMF Function only seems to work with OpenAI which is significantly slower, as well as more expensive. I notice a giant different in latency on the calls as well. Am I missing something or is Groq function calling not available on Vapi yet?
