From Anders Broman:

	handle the case where the address presentation restricted
	indicator in a location number parameter indicates the address
	isn't available;

	register as "application/isup", not "application/ISUP", as
	dissectors that use the media_type dissector table convert the
	media type to lower case, under the assumption that dissectors
	register all-lower-case media types, to make the match
	case-insensitive.
