It's been a while since I sent a fax from our Vonage line so my memory
is murky; however, I could never get our fax to work on our vonage line
until I stumbled across an obscure kb article from their site that
suggested dialing a prefix prior to sending a fax.  It was something
like *77 or *23 (that's the part that's murky).  Their techs insisted
that it was no longer necessary, but I couldn't get it to work otherwise
so the term "necessary" seemed to fit the situation.  Anyway, I would
try that first.  I would also suggest port forwarding / nating all the
SIP ports to your ATA -- I know that Vonage will tell you it's not
necessary any more, but my voice quality was awful until I did (see
above for Vonage's interpretation of necessary).  

Here is my nat table for vonage:

 WAN  	 UDP  	 5061
(ext.: edited out) 	5061  	vonage1  	
[edit rule]
		WAN 	UDP 	10000 - 20000
(ext.: edited out) 	10000 - 20000 	vonage2  	
[edit rule]
		WAN 	UDP 	123 (NTP)
(ext.: edited out) 	123 (NTP) 	vonage3  	
[edit rule]
		WAN 	UDP 	53 (DNS)
(ext.: edited out) 	53 (DNS) 	vonage4  	
[edit rule]
		WAN 	UDP 	69
(ext.: edited out) 	69  	vonage5  	
[edit rule]

If you need me to do the legwork for that kb article, let me know and
I'll dig it up this weekend.

Vonage is suppose to support the various modem and fax data standards
when run in 90 kbit/s mode and at least for some types of calls is
suppose to automagically switch to this mode.  Personally, I have never
been able to NOT use the 90 kbit/s mode so fax and modem connections
have not been a problem for me.

You can dedicate a specific amount of bandwidth to Vonage by using a
second set of traffic shaper queues but from your description it sounds
like the problem is with the cable ISP.
