[OpenSIPS-Users] B2B: how to-header is formed?

[Nick Altmann]

B2B as frontend to multi-domain proxy.

It changes from tag and breaks proxy session.

I worked around this problem this way:

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

local_route {
   if (b2b_call) {
      remove_hf("To");
      append_hf("To: $hdr(Orig-To)\r\n", "From");
      remove_hf("Orig-To");
   }
}

But I think it's not good method and b2b should have flag or variable
or another method to enable/disable from mangling.
