This was discussed briefly at a SIPit a few years ago. Outbound seems to focus on session setup, not session management. What happens if a connection goes down and a device re-registers with a new reg-id during a call?
reg-id does not need to be new. if ua looses tcp connection to ob proxy and sets up a new one, reg-id will not change. if flow tokens are in use in route set, that ua cannot be reached anymore for in-dialog requests, which is a bad thing and breaks rfc 3261. therefore, a standards compliant sip proxy cannot be configured to use flow tokens in its route uris.
After a chat with Peter I decided to send a mail to the IETF dispatch wg: http://www.ietf.org/mail-archive/web/dispatch/current/msg04855.html
