Since Net2Phone is a predefined protocol in ISA, you would have to:
1. Create bandwidth priorities for "normal traffic" and "net2phone"
2. Create bandwidth rules that use those priorities
3. Associate each with the protocol set, content set, user group, etc. that you 
want to apply it to.

The ISA help covers this quite well.

  Thanks Jim for your reply.

  I will be using Net2phone client devices and computers running the Net2phone 
application. The goals basically are to ensure that this traffic is given 
special priority, over browsing and other related services. The essence being, 
to ensure that given tolerable fluctuations in available bandwidth, the VOIP 
calls should remain clear. I quite understand the issue of ISA allocating 
bandwidth in percentages and not bps, so it obviously cannot make a particular 
amount of bandwidth always available for this application. What I really need 
to know is, how would I go about implementing it with it's given ability for my 
chosen situation.

  Thanks.

    Ade,

    That's a tall order, given the flexibility in "VOIP" standards:
    http://www.cis.ohio-state.edu/~jain/refs/ref_voip.htm

    Exactly what will you be using and what are the goals?
    Bandwidth rules can use any combination of protocol definitions, 
destination sets, etc. to control ISA traffic. 
    Bandwidth priorities deal in "percentages", not bits-per-second, so this 
may not be the answer you're looking for.

      Jim,
      You say ISA can enforce bandwidth restrictions for specific requests. 
Could you please specify which requests exactly, as i am hoping to prioritise 
VOIP traffic on my network.

      Thanks

        Yes, ISA can enforce Bandwidth priorities for any of those.

        Is it possible to configure the ISA proxy to prioritise HTTPS traffic 
over
        HTTP?

        Also, to prioritise by specific URL?
