Well, I'm trying to figure a new design for dialog module [*] so I
don't care too much how the dialog module is implemented right now :)

Yes, that's the point, the in-dialog requests. The only way is by
inspecting the route-set of the request but this involver ugly SIP URI
comparisons. But this can be really simpliffied using RR-cookies as RR
module already uses, right?
If not, the dialog hash_id could be added to the Record-Route during
loose_route().


Thanks.
