    <p>Hello,</p>
    <p>you can set per tcp connection lifetime using tcpops module:</p>
    <p>   -

    <p>You can do that when you get the INVITE, before sending a
      negative response from kamailio.cfg. Or, if you relay the invite,
      set a failure route for it and do the operation there.</p>
    <p>Cheers,<br>

        </div>
        <div>Looking to figure out the best way to allow TCP connections
          to stay alive for NAT'd clients, however, to protect against
          people just opening TCP connections to the server, I'm hoping
          to only keepalive TCP connections for connections that have
          sent an INVITE and received a 200 OK.</div>
        <div><br>
        </div>
        <div>Does this type of per-socket connection lifetime setting
          exist?</div>
        <div><br>
        </div>
        <div>For a bit more background: this is specifically for clients
          that are using the TCP connection for an INVITE. They don't
          register with the server, and as a result there's no active
          flow timer for their connection. Is there a way to enable this
          type of behavior without registering?</div>
        <div><br>
        </div>
        <div>Best,</div>
