Yes, this is achieved by changing the destination set ($du), or direct arguments to t_relay():

http://kamailio.org/docs/modules/4.0.x/modules/tm.html#t_relay

This has the effect of saying, "set the Request URI to X, but on the network (IP) and transport (UDP, TCP, etc.) level, send the request physically to Y".

Hello,

Is it possible to have Kamailio rewrite the Request URI of the INVITE message but sent the INVITE to another address first?

For example

-Kamailio (10.0.0.1) receives an INVITE

-Kamailio rewrites the RURI to 10.0.0.3

-Kamailio sends the INVITE to 10.0.0.2

-The application at 10.0.0.2 sends the INVITE to 10.0.0.3

Hi Grant,

that's easy:

$ru = "sip:$rU@10.0.0.3"; $du = "sip:10.0.0.2";

Done.

Check the $du pseudo-variable that sets the destination of the message (outbound proxy) for a request. You can also use the functions that relay/forward to specific address instead of the RURI.

So yes, it's possible.
