<p>when using the below script blocks for handling SUBSCRIBE messages, the nat_keepalive does not work as expected.</p>
<pre><code>#!ifdef NAT_TRAVERSAL_ROLE
route[PRESENCE_NAT]
{
force_rport();
if (client_nat_test("3")) {
if(is_first_hop())
set_contact_alias();
nat_keepalive();
}
}
#!endif
route[HANDLE_SUBSCRIBE]
{
if (!is_method("SUBSCRIBE")) {
return;
}
#!ifdef NAT_TRAVERSAL_ROLE
route(PRESENCE_NAT);
#!endif
if (!t_newtran()) {
sl_reply_error();
exit;
}
if(has_totag()) {
route(HANDLE_RESUBSCRIBE);
} else {
route(HANDLE_NEW_SUBSCRIBE);
}
t_release();
exit;
}
</code></pre>
<p>i believe this should be backported to stable branches<br>
Thanks</p>
