Valid phone numbers return invalid error

Hi there,
I am having an issue with phone numbers in forms.

We had a few potential adopters give feedback that the forms won’t send if they put in an address or a phone number –
until now I couldn’t reproduce it

We had a submit where the phone numbers (real numbers) were returning “The telephone number is invalid.” error
(see attached – I blurred the numbers for public forum but can provide privately)

if I put in another number in the same exact format, form sends fine with all the same fields

Any idea what might be causing this and how to fix?

Thanks
