[OpenSIPS-Users] b2b preserve header.

[Jorge Henrique Pinho]

Hi Duane,

This does not work, because b2b will generate a new message with a modified User-Agent header.
Defining User-Agent as a custom header :
modparam("b2b_logic", "custom_headers", "User-Agent")

will result in two User-Agent headers in the message created by b2b, because it will create a new User-Agent header and keep the old one.

Read this

Does that help or is that not what you are looking for?

Hi all
In b2b, is there a way to preserve headers added in opensips routine when the second leg is generated? Here is an example

route
{
               append_hf("Orig-User-Agent: $hdr(User-Agent)\r\n");
               b2b_init_request("top hiding");
}

local_route {
                if(is_present_hf("Orig-User-Agent"))
                {
                        do stuff....
                }

}

My goal is to preserve headers that b2b modules changes. Like User Agent header and To header.
