when there is double record-routing, the second is used to detect 
outgoing socket, because it is the case of transport layer bridging. 
Otherwise, for example, udp-tcp conversion will not work transparently 
and send sockets would need to be forced manually.

Via headers are for replies, which should go back through the same path 
as the request, so it might break you case, because there will be two 
Vias with the dispatcher IP.

It looks a bit strange for me that you add Record-Route to dispatcher 
and then you want the proxy to consume the Routes, but I don't know what 
you want to achieve. If there will be no transport layer bridging, so no 
double record routing, all should go fine. Actually all should go fine 
anyway, just a warning message is printed because loose routing is 
expecting a local socket on double Route headers.

Cheers,
Daniel
