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.
