Pardon me for asking such simple questions, but is
the answer for
generating re-INIVITE messages to simply use SIP clients that support

Both UA's have to support the Session-Timer draft, otherwise the inserted
Session-Expires Header will simply be ignored and you will never see any
re-INVITE's. But if both UA's support the Session-Timer they should normaly
agree on using automatically by looking at the Supported header. So in my
opinion there is no extra value in adding a Session-Expires header to a
request at a proxy.
That's actually not correct. It is sufficient in one UA supports ST. It is up to
proxy server to handle the case correctly. We do that and there are reasonable
use cases.
How does the proxy behave in this case? Are there any things the proxy
has to do to support session timer?
