How to get the phone extension?

[ssauder]

Is there a way to have the phone number extension included in the model? Right now when I enter a phone number with an extension like 9722481234x111, the model is only updated with the +19722481234 portion. I know I can still get it through jQuery using $("#phone").intlTelInput("getExtension");, but I was hoping for a more "angular" way.
