Sending a re-INVITE or UPDATE without a session-expires does not deactivate
the session timer.  It only indicates that the uac prefers not to keep it
active.  Proxies and/or the uas can still add the session-expires to keep
the functionality active.

There is currently no way the uac can turn-off the session timer
functionality when timer support is indicated by uac/uas and the proxy/uas
keeps it active.  However bumping the min-se and session-expires to a really
high value can basically produce a similar result.
