/**
* This test aims to test jain sip failover recovery.
* Shootist on port 5060 shoots at a stateless proxy on prt 5050 (scaled down version of a balancer)
* Stateless proxy redirect to Shootme on port 5070
* on ACK, the Shootme stop itself and start the other shootme node on port 5080 and pass to him its current dialogs
* on BYE or other in-dialog requests, the stateless proxy forwards to recovery shootme on port 5080
* Shootme recovery sends OK to BYE.
