Re: [Users] 404 Not found

Hi Kenny,

actually is a routing problem. the NOTIFY hits the lookup("location") and because there is no username in RURI, "404" is returned.

these requests are only ping from the phone, so your proxy should just reply them. Do something like this: if it's notify for my domain and there is no username, send stateless 200 OK.

Hi Kenny,

I think that the 404 User Not Found may be related to the "ping_nated_only" parameter you have set.

I've seen this message in my traces as well. Been too busy over here to track this down as a "real problem" or a "non issue" related to pinging a NATed device. It may be specific to Sipura devices.

Regards, Norm

Hello all, I've registered my SPA 3000 on my openser server. It logs in and everythin works fine. However I was wondering why do I get this 404 Not found when I do ngrep -qt port 5060. What is causing this? And how do I get rid of it?
