Yes they are but the implementation looks for a valid registration record to
initiate pn. The route snippet at the blog post looks for the pn enabled
registrations with return code 2 then pops up the E_UL_CONTACT_REFRESH event,
and waits for a registration from the UA to proxy the call.
# do lookup with method filtering
lookup("location", "m");
$var(rc) = $retcode;
switch ($var(rc)) {
case 1:
# we found at least 1 non-PN contact!
$var(do_relay) = true;
break;
case 2:
# success, but all contacts are PN-enabled, so we're
# sending PNs / awaiting re-registrations from them
$var(do_relay) = false;
break;
default:
xlog("L_INFO", "DBG: no contacts found ($var(rc))\n");
t_reply(404, "Not Found");
exit;
}
...
if ($var(do_relay) && !t_relay())
send_reply(500, "Internal Server Error");
...
So practically, UA should keeps its registered state active, so needs a
registration refresh in regular intervals. That is not the ideal case for a
mobile app I believe. So the main idea is to keep power consumption at minimum.
