Steps:

Enter 'Phone No' in component field.

Selected 'Phone Number' as field type.

Clicked 'Add'

Country was selected as 'US/Canada' (I am accepting only US/Canada 10 digits)

Separator field has dash(-)

Problem:

When I visit my form, I see a one field which allows to enter more than 10 digits.

How can I make sure I can enter 10 digits numbers (separated with dashes) with upto 4 digits extension?

You could add a phone field as you described for the phone number.

And add another field of type number for the phone extension, you can limit this field to be only numeric and 4 digits.

And even to make sure that the phone number is introduced and not only the 'phone extension', you can add a Webform conditional to display the 'phone extension' field only if the 'phone' field has been filled.
