The Kamailio websocket module sends WebSocket pongs in response to WebSocket pings from websocket clients.  It can also be configured to send WebSocket pings on idle connections (and does so by default).

There is no TCP level stuff here, this is all at the WebSocket layer.

since websockets uses tcp, kamailio running on linux should
automatically do tcp level keepalives.
