@Mattia Good morning, Mattia! To extract the date and time from the call, you can utilize natural language processing (NLP) techniques to parse the spoken content. If the voice content is transcribed into text, you can then apply date and time recognition algorithms to identify and extract the datetime information. For your outbound assistant, you could implement a system that listens for specific phrases or patterns that indicate scheduling intent, such as "schedule an appointment," "set up a meeting," or "call me back on." Once such phrases are detected, the system would focus on extracting the subsequent date and time information. If you're looking to integrate this functionality into your system, you might need to use a specialized NLP service or library that can handle date and time extraction from text. Unfortunately, there isn't a specific tool or function within VAPI that directly extracts datetime from JSON. However, you can design your system to capture the user's spoken input and then process it with an external NLP service that offers datetime parsing capabilities. If you have the transcribed text and need assistance with implementing the NLP part, please let me know, and I can guide you through the process or suggest some services that could help with this task.
