[Freeswitch-users] using enable_heartbeat to detect network problems in event_socket

[Babak Yakhchali]

no. if socket is closed, an exception is thrown and you can catch it and
handle it. but if for example your connection is lost, socket will be open
till keep alive timer expires. this keep alive is os based and you can not
set it for every socket (may be I'm wrong about this part).
