### Description Cannot use `tcp_keepalive_enable` function on master branch. #### Reproduction Create config file like ``` listen=udp:127.0.0.1:5060 loadmodule "pv.so" loadmodule "tcpops.so" #modparam("http_client", "httpcon", "http://example.com=>http://example.com"); request_route { tcp_keepalive_enable("22", "60", "5", "2"); } ``` and then start Kamailio #### Log Messages ```
