4. User Agent Client Behavior: Sending a Replaces Header
A User Agent that wishes to replace a single existing early or
confirmed dialog with a new dialog of its own, MAY send the target
User Agent an INVITE request containing a Replaces header field. The
User Agent Client (UAC) places the Call-ID, to-tag, and from-tag
information for the target dialog in a single Replaces header field
and sends the new INVITE to the target.*/
