From the SIP RFC:

...This modification can involve changing addresses or ports, adding a media stream, deleting a media stream, and so on. This is accomplished by sending a new INVITE request within the same dialog that established the session. An INVITE request sent within an existing dialog is known as a re-INVITE.

Note that a single re-INVITE can modify the dialog and the parameters of the session at the same time.

re-INVITE caused a lot of trouble if we don't know exactly what's going on with UAC/UAS at the time re-INVITE happen.
