is the phone line stable..meaning no distortion ... if there is some distortion like static sound.. you won't be able to fax properly.. try enable to ECM mode in your fax unit.. ECM is error correction mode.. it should reduce the send/rec error...

Error code 322- There was a communication error with the receiving fax machine due to poor telephone line conditions.
Solution
Set the receiving machine to receive at a slower transmission speed
If the session fails after sending several pages of a large document, resend the document as several smaller documents.
Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error code 358--
The remote user pressed the Stop key,
The remote machine encountered a system problem such as no paper or a paper jam.
Try
Configure the local fax machine to use a slower reception speed.
Disable ECM mode on your machine.
Try sending a fax to another location.

This means that you have a memory transmission failure.

Can be caused by attempting to fax in the wrong mode. Use direct transmission method.

I turned off error correction mode and fax went no problem and no errors on it.

The other fax machine is not G3, which is the latest configuration. Maybe a very old fax machine.
