I am having an issue handling UN-REGISTERs.
This is my config file:
route{

if (uri==myself) {
if (method=="REGISTER" &&
(!search("expires=0"))) {
if (!www_authorize("", "subscriber")) {
www_challenge("", "0");
exit;
};
save("location");
xlog("L_INFO","mylog: save-location
successful.\n");
exit;
}

# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
sl_send_reply("404", "Not Found");
xlog("L_INFO","mylog: lookup-location failed, sending 404
Not Found. Method: [$rm].\n"); exit;
};
append_hf("P-hint: usrloc applied\r\n");
};
route(1);
}
I added the "&& (!search("expires=0"))" to make sure that
only the REGISTER
requests will be processed by the next lines and the AOR will be saved in
those cases. The X-lite sends "expires=0" in the Contact HF when it is
unregistering. This is how the processing of a REGISTER looks like as per
my code:
Hi Fabian,
somehow the search(..) does not match, so the REGISTER case is not used for
unregistrations. My twinkle e.g. uses uppercase at the beginning in certain
cases, you only match for lower case at the moment. But instead of changing
the match i'd just let the registrar handle this in save(). It should work
just fine.
Unregistration requests are then proceeded by the lookup, and of course no
contact is found for this URI. If you comment the lookup block out, you'll
get a loop, as its visible from the log below.
