Since requests other than INVITE are responded to immediately,
sending a CANCEL for a non-INVITE request would always create a
race condition.
The following procedures are used to construct a CANCEL request. The
Request-URI, Call-ID, To, the numeric part of CSeq, and From header
fields in the CANCEL request MUST be identical to those in the
request being cancelled, including tags. A CANCEL constructed by a
client MUST have only a single Via header field value matching the
top Via value in the request being cancelled.*/
