Phone number format alternatives are

1. ###-###-####
2. # ###-###-####

Dial/call logging works for the phone number 214-555-5555. (obviously using a real number)

Dial works for the phone number 1 214-555-5555. Call logging does not work, it cannot find the contact.

If I change the Phone number format alternatives to 1 ###-###-#### then 1 214-555-5555 works.

Is this the expected behavior?
