It sounds like you're referring to the ability to set a specific server URL for handling requests related to a phone number in VAPI. If you're noticing that this feature isn't available or isn't working as expected, it could be due to a recent update or an unintended issue.
To assist you better, could you please provide more details? Are you unable to find the option to set the server URL, or is it not functioning correctly when you try to use it? Once I have more information, I'll be able to help you more effectively.
