[OpenSIPS-Users] sip question.

The BYE request is constructed as would any other request within a dialog,
as described in Section 8.1.1.
[…]
The Request-URI, To, From, Call-ID, CSeq, Max-Forwards, and Via header
fields MUST be included in a BYE request.
A Contact header field MAY be included in a BYE request.
