It's definitely a NAT issue. The phone is not responding to your 401 and is instead just sending another REGISTER packet. Notice that FS is responding on port 5060. Is that the port your phone is expecting to receive on?<br>

Hi,<br>
<br>
here is pastebin of siptrace (<a href="http://pastebin.freeswitch.org/19029" target="_blank">http://pastebin.freeswitch.org/19029</a>).<br>
<br>
Phone on local network are registered on FS. After I put between local<br>
network and Phone router, phones are unable to registered on FS.<br>
<br>
On other softswitch which is not FS phones are registering (same port,<br>
same scenario, etc.).<br>
<br>
Phones are SPA922.<br>
<br>
What could be causing the problem?<br>
<br>
Thanks!<br>
<br>
Miha<br>
