[Freeswitch-users] How to disable TCP Keepalive on a TLS connection?

[Master Can]

When digging further into the source code, I found in
libs\sofia-sip\libsofia-sip-ua\tport\tport_type_tcp.c:

#if defined(SO_KEEPALIVE)
  setsockopt(socket, SOL_SOCKET, SO_KEEPALIVE, (void *)&val, sizeof val);
#endif
  val = 30;
#if defined(TCP_KEEPIDLE)
  setsockopt(socket, SOL_TCP, TCP_KEEPIDLE, (void *)&val, sizeof val);
#endif
#if defined(TCP_KEEPINTVL)
  setsockopt(socket, SOL_TCP, TCP_KEEPINTVL, (void *)&val, sizeof val);
#endif

The 30 seconds are hardcoded...
Now to turn off keepalive, I'd have to change the header file where
SO_KEEPALIVE is set and to compile freeswitch?

Is there a more straightforward way?

br,
Can
