Hi, Is "Event: Refer" header mandatory in a REFER request?
RFC 3515 says: A REFER request implicitly establishes a subscription to the refer event. Also there is no mention on Event header in Section "2.2 Header Field Support for the REFER Method" Hence I think Event header is NOT mandatory in REFER request. But I understand that it is mandatory in the SUBSCRIBE, NOTIFY that might be sent on the REFER dialog. Is this correct?
