(Mark Mandel, IMO HQ 5.2:20):  I had been working with Marc Okrand by phone and e-mail during the project [i.e. the Language Lab on the Star Trek: Klingon! CD-ROM], and so I sent him the text of my transliterated Klingon letterhead, asking especially about my word for fax, which at the time was a compound word with no space. He wrote back, approximately, that he liked the idea, but he would prefer to express it as a two-word phrase, nav HablI'; and he also suggested the corresponding ghogh HablI' for telephone.
