[SR-Users] RTPEngine call associations

Hi, When using a single RTPEngine, or a single RTPEngine per set, it is possible to make stateless RTPEngine calls from Kamailio, since everything is keyed by Call-ID + tag. In other words, one can set up a call, answer it, restart Kamailio, and still send a 'delete' to RTPEngine successfully because there's no runtime state that needs to persist within Kamailio. How does this work with multiple RTPEngines in a set? There is clearly some runtime state being kept to map (Call-ID, tag) => <RTPEngine instance within a set>, otherwise successive stream management commands would be round-robined within the set just like initial 'offer' commands. I take it this association is lost across Kamailio restarts, since I see no mechanism to persist it. Does that mean that subsequent stream management commands (e.g. updated 'offer' / 'answer' on re-INVITE, 'delete' on BYE) are blasted out to all instances within a set prophylactically? Or is the recipient instance chosen at random as it would be with an initial 'offer' command?
