Hi Yuriy,
the tcp_keepalive_enable() function will send keepalive packets at TCP
level, not at application level (SIP OPTIONS). It can be used to check
if the remote peer connection is still valid, and close the TCP
connection on the server side if it is no more valid. If you enable the
TCP keepalives, you should see these packets using tcpdump or wireshark.
Along with "handle_lost_tcp" option on usrloc, this can be used to
maintain the usrloc table as consistent as possible.
