Module address 

Address headers: From, To, Contact, Route, Record-Route, Refer-To.

All share one grammar (RFC 3261 §20.10, §20.20, §20.39):

( name-addr / addr-spec ) *( SEMI generic-param )
name-addr = [ display-name ] LAQUOT addr-spec RAQUOT

The trap is the bare addr-spec form: without angle brackets, a semicolon starts a header parameter, not a URI parameter, so sip:a@b;tag=1 is one URI and one header parameter — while <sip:a@b;tag=1> is one URI with a URI parameter and no header parameters. The two mean entirely different things and differ by two characters.
