      Try both the encoded and unencoded subscription URI for a match in hints.
      
      When a phone sends an encoded URI for a subscription, the URI is not matched
      with the actual hint that is in decoded format.  For example, if we have an
      extension with a hint that is named: "#5601" or "*5601", the subscription will
      work fine if the phone subscribes with an already decoded URI, but when it's
      decoded like "%255601" or "%2A5601", Asterisk is unable to match it with the
      correct hint.
