RE: [Enum] DNS for E.164-IP Address Mapping

I read the Vaha-Sipila draft and I had trouble with understanding if it was
pertinent to have such distinct URLs due to the fact that a same E.164
number can correspond to a fax or to a phone. In that case, would the number
be part of two URL schemes, .tel and .fax ?
I thought it would have been more convenient to stick to one URL like P.
Faltstrom's .e164.int in his "E.164 number and DNS draft" and different
protocols. But maybe I totally misunderstood each draft ? And .e164.int is
not a URL scheme as .tel, .fax and .modem are ?
Thanks for giving me some lightson this issue.

Well for telephony applications there is a draft outlining how the URL's 
should be defined. I'm sure if there were other types of applications that 
need to be referenced in NAPTR records... Universal Messaging Servers, 
T.38, it should be no trouble defining a simple registration procedure.

Jonathan.... one of the things I'm increasingly concerned about is DNS 
security here. Do you have any thoughts on how much of DNSSEC we might have 
to require?

Title           : URLs for Telephone Calls
         Author(s)       : A. Vaha-Sipila
         Filename        : draft-antti-telephony-url-12.txt
         Pages           : 22
         Date            : 29-Dec-99

This document specifies URL (Uniform Resource Locator) schemes
'tel', 'fax' and 'modem' for specifying the location of a
terminal in the phone network and the connection types (modes of
operation) that can be used to connect to that entity. This
specification covers voice calls (normal phone calls, answering
machines and voice messaging systems), facsimile (telefax) calls and
data calls, both for POTS and digital/mobile subscribers.
