Hello,
I am trying to upgrade from kamailio 1.4 to 4.0.

I am having an issue with call forwarding: I send the call to a subscriber (location) and if it doesn't answer, there is a failure_route to do the forward.

It is something like this:

failure_route[1] {
        $ru = "sip:0313241342@192.168.2.2"
        append_branch();

}

However, the INVITE is sent to both the subscriber location and the new branch.

So, is it now necessary to somehow to "drop" the original branch?

If so, how do I do that?

Regards,
Takeshi
