[SR-Users] What IP in REGISTER message does Kamalio use to store location ?

[Vitaliy Aleksandrov]

Save() function of the "registrar" module always saves Contact and can 
save real source to the "received" field of a location record.
lookup() function uses Contact to form R-URI and puts ip:port from the 
received field to the $du.
If $du is present t_relay() uses it to forward a request to a correct 
destination.
