How do I add an extension to a phone number in Contacts 7.1?
Now that the perfectly servicable Address Book has been replaced by overly complicated Contacts 7.1 in OS 10.8.3, I cannot add an extention to a telephone number. A phone number with an extention ends up looking like "4155551234ext3710484". Creating a new field named "ext" doesn't help, as any number entered into this field that is longer than 3 digits is autoformated to a phone number. Some of my contacts now have 6 digit extensions!
Contacts Help is no help whatsoever. Very frustrating.
