I am testing out a Dialog Engine Bot asking for the end customer to input their Phone Number. I have created the Slot Type and added in the regular expression of ^\+\d{1,3}d{2,3}d{2,3}d{4} which should format out to e.g. +18005551212, and in testing with a 3rd party tool it works. When I execute the Bot and it asks for a phone number I get a "Sorry. Please give me your phone number again". If I enter the phone number in as +1 800 555 1212 it works. I don't have any spaces \s in my RegEx so why does it work inputting a space? What should the RegEx format for an E.164 look like? Thanks.
