Adding Customer phone number to order confirmation email

is it possible? did anyone do this?
if so, could you direct me to how?

Admin -> Content Management -> Message Templates

Edit either OrderPlaced.CustomerNotification or OrderPlaced.StoreownerNotification or both, if you want.

Add this token to the body where you want it to show up:  %Order.BillingPhoneNumber%.  You can also use %Order.ShippingPhoneNumber%.  Just don't use %Customer.Phone% because it won't work with these two templates.

thank you!
easy and painless :)
