The problem is when i type invalid phone number say 512345678 (didn’t start with 05 and length is not 10) the input is matching with booking_numberintent or somtimes matching withbooking_numberentity and filed the slotbooking_number. I don't want this behaviour, cause it's create so many problem. Why this kind of user input matching with booking_number` intent/entity? How can i resolve this?

It’s hard to say exactly what is happening, but I think that because the numbers like 32342563 are substituted with __NUMBER__ token, so that content of a number is irrelevant, your input doesn’t fall under either of regexes, so the classifier predicts most probable class.

The recommended way would be to have joint intent input_number and abstract entity number, then use custom action to disambiguate the number using regex
