Thank you very much for your support, When you say: "They may be able to disable this for you – otherwise you’ll need to rewrite the headers yourself."
How can I rewrite the header if I dont have destination IP?, there are four Asterisk servers and all of them send calls to the bridged Kamailio and I dont have Asterisk private IP in the BYE request.
