A UAC MAY include a Session-Expires header field in an initial

session. The value of this header field indicates the session
interval desired by the UAC. If a Min-SE header is included in the
initial session refresh request, the value of the Session-Expires
MUST be greater than or equal to the value in Min-SE.
The UAC MAY include the refresher parameter with value 'uac' if it
wants to perform the refreshes. However, it is RECOMMENDED that the
parameter be omitted so that it can be selected by the negotiation
mechanisms described below.
