Re: [Users] 404 Not found

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?
