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.
