/// <remarks>
/// From RFC 3261 Chapter 17.1.1.3 - ACK for non-2xx final responses
///
/// IMPORTANT:
/// an ACK for a non-2xx response will also have the same branch ID as the INVITE whose response it acknowledges.
///
/// The ACK request constructed by the client transaction MUST contain
/// values for the Call-ID, From, and Request-URI that are equal to the
/// values of those header fields in the request passed to the transport
/// by the client transaction (call this the "original request"). The To
/// header field in the ACK MUST equal the To header field in the
/// response being acknowledged, and therefore will usually differ from
/// the To header field in the original request by the addition of the
/// tag parameter. The ACK MUST contain a single Via header field, and
/// this MUST be equal to the top Via header field of the original
/// request. The CSeq header field in the ACK MUST contain the same
/// value for the sequence number as was present in the original request,
/// but the method parameter MUST be equal to "ACK".
///
/// If the INVITE request whose response is being acknowledged had Route
/// header fields, those header fields MUST appear in the ACK. This is
/// to ensure that the ACK can be routed properly through any downstream
/// stateless proxies.
///
/// From RFC 3261 Chapter 13.2.2.4 - ACK for 2xx final responses
///
/// IMPORTANT:
/// an ACK for a 2xx final response is a new transaction and has a new branch ID.
///
/// The UAC core MUST generate an ACK request for each 2xx received from
/// the transaction layer. The header fields of the ACK are constructed
/// in the same way as for any request sent within a dialog (see Section
/// 12) with the exception of the CSeq and the header fields related to
/// authentication. The sequence number of the CSeq header field MUST be
/// the same as the INVITE being acknowledged, but the CSeq method MUST
/// be ACK. The ACK MUST contain the same credentials as the INVITE. If
/// the 2xx contains an offer (based on the rules above), the ACK MUST
/// carry an answer in its body. If the offer in the 2xx response is not
/// acceptable, the UAC core MUST generate a valid answer in the ACK and
/// then send a BYE immediately.
