I'm asking mainly because of REFER 481 impacts; however the answer also has potential implications concerning draft-ietf-sip-info-events. RFC 5057 appears to imply that it is part of the subscription usage; however I'm not positive if my interpretation and/or RFC 5057 is correct. If REFER isn't considered part of the INVITE usage, how should REFER 481 be interpreted? More specifically, should receiver of REFER 481 send BYE?
