[OpenSIPS-Users] DNS-SRV query in opensips

[Bogdan-Andrei Iancu]

Hi Agalya,

seturi() and setdsturi() set the RURI / DestinationURI for the current 
message / branch.

When youdo an append_branch() a new branch is stored for serial/parallel 
forking (note that the current branch does not changes - this is branch 
number 1).

So, append_branch() will make a copy of the current branch (RURI, DURI, 
PATH, Forced Socket, etc) and store a new branch for later forking.
