This Record-Route means that the UAC MUST send the ACK to address 
192.168.1.101 adding a Route header with same content. Is it feasible for the 
UAC to send the ACK to that private address?

This Contact means that, when the ACK arrives to the proxy, it must forward it 
to address 233.32.345.5:5800 (since proxy does loose_routing and deletes top 
Route).
