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.
