RFC 3966 explicitly states that 'tel' URIs may not represent a dial
string.  That leaves no way specify a dial string in a standardized
way.  Great confusion exists with the SIP URI parameter "user=phone",
and specifically, if it can represent a dial string.  This memo
creates a new value for the user parameter "dialstring", so that one
may specify "user=dialstring" to encode a dial string as a 'sip:' or
'sips:' URI.  [STANDARDS TRACK]
