Well, that would do it, certainly.

Feel free to search the archives for "VoIP" and see what you come up 
with (recent posts especially).  The bottom line is that VoIP is not a 
reliable means for facsimile communication.  Luck may vary, but faxing 
with VoIP lines crossing the internet will almost certainly be 
problematic at best, I suspect.

FoIP is a different story, but I sincerely doubt that you're Vonage 
adapter does T.38.

If Vonage has somehow indicated to you that these VoIP lines are usable 
with fax, then I suggest that you contact them and tax their customer 
support resources until you feel inclined to get PSTN lines.
