Well, I personally prefer to do rr on the LB, because you can then
perform a failover to another proxy on the LB if the specific proxy
fails. Think of a scenario where LB routes the INVITE transaction to
proxy P1 selected by Call-ID hashing, and after successful
call-establishment P1 fails. If the BYE then hits LB, it will try to
route it to P1 again because of the same Call-ID, and after hitting a
timeout, a fallback to P2 can be performed. So no failover has to be
implemented in the UACs.
For accounting purposes, the acc-records can be collected from all of
the proxies to create the CDRs.
Just my 2 cents,
