Section 20:
The Contact, From, and To header fields contain a URI. If the URI
contains a comma, question mark or semicolon, the URI MUST be
enclosed in angle brackets (< and >). Any URI parameters are
contained within these brackets. If the URI is not enclosed in angle
brackets, any semicolon-delimited parameters are header-parameters,
not URI parameters.

For sure,
Fromtag MUST be a header param and not a URI param (as
Fromtag is defined to be a header param in RFC3261).
I am also positive about this, if there are no arrow brackets, then it is a
header parameter. But I cannot say now exactly where is specified.
