Help!! FAX using cell phone connected to laptop

Hello technical gurus,

What is the process to send/receive FAX using cell phone service and a
laptop?

That is, how can I connect the cell phone to the laptop, and then fax
documents from laptop using the phone service of the cell phone? And,
is there a way to receive fax on my computer using the cell phone.
Priority remains with sending out the fax.

Technology:
Cell phone: Samsung E335 Camera Flip cell phone
Cell service: T-mobile
Laptop: Toshiba Satellite running Windows XP (has USB and telephone
landline connector)

Please let me know if this information is available elsewhere (please
send links). BTW, I called Tmobile tech support and was informed "you
can't do this. Thanks for using Tmobile".

Thanks!!

Gratefully,
