Hello, In fact, my goal is to avoid this type of issue (please see below the call flow): I want kamailio sends a CANCEL request to asterisk if the uac lost tcp connection during three-way - I cannot use PRACK method.
The ideal would be that Kamailio sends a CANCEL request before asterisk generates the 200OK. Any help will be appreciate.
