<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>
<br>
"INFO:presence:handle_expired_subs: notify"<br>
