<p>If tcpdump not showing any incoming packets from the phones, then the phones are not communicating with the server. There could be no other reason other than iptables blocking that communication.</p>
<p>Did you check if iptables is blocking anything?<br></p>

there is just no registration coming in. SIP debug shows nothing on the
SIP peers that do not register. TCPdump shows nothing on incoming
registrations. Firewall is down.<br>
<br>
I'm using SIP realtime and I'm starting to think it is a problem with
the MySQL-DB of the MySQL-driver or something...<br>
<br>
The thing that made it all work again (after reloading, restarting
asterisk and the whole CentOS-server) was recompiling asterisk 1.4.30
and addons 1.4.11...<br>
<br>
I'm still looking for an explanation so I can act quicker the next time
this should re-appear.<br>
<br>
<br>
According to you, what logfiles could tell me some more ??<br><font color="#888888">
