Bluetooth fax modem

I'm trying to setup a Nokia E65 as a bluetooth modem to send a fax. The phone is already setup as a bluetooth device and sync's with iSync perfectly.

In Print & Fax options, I've added E65-Dialup-Networking as a fax device without any problems. However, when printing a document in Pages then trying to send it by fax, it sits in the fax queue indefinitely. The CUPS error messages are:

There isn't much information available online - and I'm desperate. Someone help me before I pull my hair out!
