Fax Communication Error 344 on HP Envy 7645 (7640 Series)

[Mel_C_FL]

This is an older unit, but has worked very well.  For some reason it suddenly stopped faxing and gave us a Communication Error 344.  The only thing that changed recently was unplugging it to put a new multi-outlet base into the receptacle we used.  Since then, it will dial and we can hear the other end answer and our printer says connecting, but then the first page just passes straight through and we get a 344 communication error.  we tried to fax to several different faxes with identical results.
