I have a question similar to this one: How can I display my Twilio number for inbound calls
However, I now have two separate Twilio numbers that both point to the same URL, so hard-coding the number as Caller ID is no longer an option. Is there a method I can use to get which Twilio number was called? I know that PhoneNumber gets the caller's number, so I need a way to distinguish which of my two numbers are calling.
