I noticed the faxing app within "messaging" on my 9300i. I followed the instructions (online manual) and faxed using Documents > Sent Via > Fax.

The app tries faxing but always fails leaving the fax in my outbox. Do I need to subscribe to some extra services for this to work? I was hoping the phone would call the fax# and do the "handshake" directly and transmit using regular voice minutes. Am I missing some setting?
