  "abstract": "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]",
