Hello,<br><br>No, there no NAT in my test network, just simple static routing. <br>also, No. There is no other Error message before that "udp_send" ERROR message.<br><br>One
thing that I would like to ask is, I did not install "pua" modules. Are
they necessary if I am implementing simple presence server i.e.
everyone is allowed to see the presence of each other. <br>
<br>Thank you.<br><br><div class="gmail_quote">On Mon, Nov 5, 2012 at 8:36 PM, Bogdan-Andrei Iancu <span dir="ltr"><<a href="mailto:bogdan@opensips.org" target="_blank">bogdan@opensips.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<tt>Hi,<br>
<br>
Do you have any kind of NAT in your used network (like one of the
clients behind a NAT) ?<br>
<br>
Also, before the "udp_send" ERROR, do you see any other error from
the same process ?<br>
<br>
Regards,<br>

I am trying to set up a lab. I have 2 DHCP servers and a SIP
server.<br>
<br>
My DHCP server ans OpenSIPS are working fine. But, when I register
my clients to SIP server, I can not see there presence, though I
can make call between clients. <br>
<br>
I get these messages, <br>
<br>
