Aren't there security concerns with supplying a URL from a Calling party to

Certainly. And what file format describes ringing anyway?!? That's why I've only seen "127.0.0.1" used in the URL.

In this usage the URL is the message.  "Bellcore-dr3" refers to
Bellcore's Distinctive Ring 3.

Again, not a standard.  But personally, I would probably use
Alert-Info similarly before I created a new header.

Alert-Info: and the use of an URL are standard.

I've seen more than one system use this form

        Alert-Info: <http://127.0.0.1/Bellcore-dr3>

to indicate a DR, but I don't think it's a standard.
(Google will turn up some examples.)
