[Users] Usage of record_route_preset / dispatcher / UAC-Module

[Bogdan-Andrei Iancu]

Hi Carsten,

just a short note...on the sip proxy you should do rr with the proxy's 
IP and not with the one of the LB. Once the LB decides which proxy 
handles the call, all sequential request must go through that proxy and 
ideally to skip the LB.

regards,
bogdan
