HI Daniel<div><br></div><div>SCPE - open internet, no NAT in front, nor any firewall. Device is on a simple network with a TP-Link router which means it's behind NAT. What could be the cause of the SCPE not detecting NAT?<br>

<div>Hi Theo,<br>
If SPCE didn't figure out that your client is behind nat, then it
won't perform the nat_sipping.<br>
What are the network of your client,of your NAT device and of your
SCPE ?<span class="HOEnZb"><font color="#888888"><br>

<div>Nope, the problem persists. Been fine for a couple of hours.
Then all of a sudden - local user offline. Will try 2, 3 times,
then the 4th time it's online again, presumably because a
registration came through or whatever.......<br>

Hi Daniel
<div><br>
</div>
<div>I have just tried that - let's see if it does the
trick. I had assumed that a new registration attempt every
30 seconds or so would do the trick. Strange enough, it
DOES sent a registration, but the webinterface on sipwise
shows the last registration as 30 minutes ago. It also
shows, under active registrations NAT = no. But the phone
is behind NAT - is there a setting similar to ASTERISK
where one specifies that or is it meant to just detect it?</div>

<div>Hi,
<div>if the client is behind nat you can try to
set a nat keep alive on the snom. </div>

Hi
<div><br>
</div>
<div>With the help of this list I have upper
registration working and can phone between
extensions. However, at (seemingly)
random, the devices cannot be reached. All
appears fine and they appear registered,
but when I make the call it doesn't work,
until I log into my device and click
"re-register". The proxy log is fairly
clear:</div>

<div>Feb 15 08:13:22 sipwise
/usr/sbin/kamailio[2138]: INFO:
<script>: Local user offline -
<a href="mailto:R=sip:user404@my.domain.com:5060;uuid=c6d7434d-5026-4394-86d5-d3c43d2fd2cc" target="_blank">R=sip:user404@my.domain.com:5060;uuid=c6d7434d-5026-4394-86d5-d3c43d2fd2cc</a></div>
<div><br>
</div>
<div>telling me that the user is offline.
Question of course is - how do I avoid
them going offline. The phones are set to
re-register every 60 seconds, but that
doesn't seem to do the trick. Once this
happens, only a physical "re-register" the
phone by doing it manually gets it back up
again. This is with SNOM 300 phones.</div>
