As clarification, I use rev 4943 with a UDP client (Twinkle) who
doesn't register, but subscribes to presence.

SUBSCRIBE:
   nat_keepalive();
   ...
   t_newtran();
   handle_subscribe();
   t_release();


If I delete "t_newtran()" between "nat_keepalive()" and
"handle_subscribe()" then keepalive works and I see:

# opensipsctl fifo get_statistics nat_traversal:
nat_traversal:keepalive_endpoints = 1
nat_traversal:registered_endpoints = 0
nat_traversal:subscribed_endpoints = 1
nat_traversal:dialog_endpoints = 0


but if I leave that "t_newtran()" call then the subscriber is not keep-alived:

# opensipsctl fifo get_statistics nat_traversal:
nat_traversal:keepalive_endpoints = 0
nat_traversal:registered_endpoints = 0
nat_traversal:subscribed_endpoints = 0
nat_traversal:dialog_endpoints = 0


I've confirmed it right now.
