Is this a Snom phone by any chance? I know they use NOTIFY messages as a
keep-alive, although a few others do as well. In my config, I have a section
to handle just that:
if((method=="NOTIFY") && search("^Event: keep-alive"))
{
sl_send_reply("200", "OK");
break;

Yes I think it is just a keep-alive.
Thanks also to "Michal Matyska" <michal(a)iptel.org> who wrote:
A UA is trying to send NOTIFY:
U 1.2.3.4:56839 -> 5.6.7.8:5060
NOTIFY sip:machine.foo.com SIP/2.0.
There is no user in this NOTIFY message. So there is nothing that SER
can lookup. This is probably just a keep-alive. Hmmm,
could you tell me from the message dump, which user do you want to lookup?
This is what I don't understand, where is the user name located ?
What alternative action is there be if you have:
if (!lookup("location")) {
sl_send_reply("404", "User Not Found -
lookup_location"); break; };
So, what causes the lookup in userloc db to fail ?
As Michal points out, for a keep-alive message like this one
there is no user in the usrloc dbso it must return a 404 error ?
Is the UA sending the keep-alive doing the wrong thing ?
