[OpenSIPS-Users] Help with "t_relay"

[Bogdan-Andrei Iancu]

Hi Spandy,

What you have is one URI (A) that you want to send to 2 destinations (X 
an Y). So you need to create a new branch with the same uri (A) but to 
point to a different destination:

$ru = "sip:user at domain";  # set initial URI
append_branch();          # clone it as a new branch with the same URI

$du = "sip:ip_pbx1:5060";  # set destination for initial URI
$(branch(duri)[0]) = "sip:ip_pbx2:5068;transport=tcp"; # set destination 
for new branch
