Unable to change $td(to domain) in kamailio cancel requests

[premkumarramasamy]

Description

Hi Team,
I am using kamailio as load balancer in my organization and I want to manipulate the cancel request from and to headers.
But kamailio is changing the requests when it sends out and its still using the one it receives from other end.

How do I change the kamailio to change the to domain when it sends the cancel request out?

Troubleshooting

Code to handle cancel
if (is_method("CANCEL")) {
if (ends_with($td, "incoming.req.com")) {
xinfo("Updating CANCEL request");
uac_replace_to("sip:@manipulated.to.domain.com");
$uac_req(turi)="sip:@manipulated.to.domain.com";
append_hf("To: <"sip:@manipulated.to.domain.com">");
#uac_req_send();
xinfo("Updating CANCEL request TD: $td");
}
if (t_check_trans()) {
route(RELAY);
}
exit;
}

Reopening the ticket will not give you more answers...
The CANCEL have to match the INVITE sent by Kamailio. It may be different to the incoming INVITE.

Let's keep this on the list.
