To enable the assistant to hold the line when requested, you would need to implement a feature that recognizes the phrase "please hold while I transfer you" or similar phrases indicating that the call should be put on hold. Once the phrase is detected, the assistant should pause any further speech output and wait for the call to be transferred.
If you're looking to implement this feature, you may need to update the assistant's call handling logic to include speech recognition capabilities that can detect hold requests. Additionally, you would need to define a protocol for how long the assistant should wait on hold and what to do if the call is not resumed within a certain time frame.
Since this is a more complex feature that may require updates to the assistant's programming, please let me know if you need further assistance or guidance on how to proceed with this implementation. If there are specific functions or tools within VAPI that you think could help with this, I'd be happy to discuss those as well.
