 There are three methods for sending DTMF in a phone call:
 
-1. **In-band DTMF**: DTMF tones are transmitted as part of the regular audio stream. This is the simplest method, but it can suffer from quality issues if the audio stream is compressed or degraded.
-2. **Out-of-band DTMF via RFC 2833**: This method sends DTMF tones separately from the audio stream, within RTP (Real-Time Protocol) packets. It's typically more reliable than in-band DTMF, particularly for VoIP applications where the audio stream might be compressed. RFC 2833 is the standard that initially defined this method. It is now replaced by RFC 4733 but this method is still referred by RFC 2833.
-3. **Out-of-band DTMF via SIP INFO messages**: In this approach, DTMF tones are sent as separate SIP INFO messages. While this can be more reliable than in-band DTMF, it's not as widely supported as the RFC 2833 method.

-As of writing, Vapi's DTMF tool uses in-band DTMF. Please note that this method may not work with certain IVRs. If you are running into this issue, the recommended approach is to have your assistant say the options out loud if available. For example, when an IVR says "Press 1 or say Sales for the Sales department," prefer having the assistant say "Sales."

 If the `serverUrl` is not defined either at the account level or the assistant level, the function call will simply be added to the chat history. This can be particularly useful when you want a function call to trigger an action on the frontend.
 
 For instance, the frontend can listen for specific function calls in the chat history and respond by updating the user interface or performing other actions. This allows for a dynamic and interactive user experience, where the frontend can react to changes in the conversation in real time.
