To the best of my knowledge As per the grammar defined in
"draft-levy-sip-diversion-08" both would be correct.
Even though the tag names 'unconditional' and 'off' is uniquely
defined, One can argue that the quoted ones fall under the quoted-string
part. I would support both for the shake of inter-op with other devices.
diversion-reason = "reason" "="
( "unknown" | "user-busy" | "no-answer" |
"unavailable" | "unconditional" |
"time-of-day" | "do-not-disturb" |
"deflection" | "follow-me" |
"out-of-service" | "away" |
token | quoted-string )
diversion-privacy = "privacy" "=" ( "full" | "name" |
"uri" | "off" | token | quoted-string )
