As I said earlier, the firewall was down. I'm using LFD&CSF.

If it had anything to do with the firewall, how can the problem be resolved by recompiling asterisk and asterisk-addons ?

Yesterday everything went well, this night something happened I guess, and this morning on some locations some phones (of all types of brand) showed a failed registration and rebooting the phones did not help (neither did reloading/restarting asterisk or the entire server)...

To make an example : some Snom M3 phones were registered, some Snom 320 were not, on my own Cisco SPA942 2 out of 4 SIP-accounts were registered (the other two would not register after several reboots).

It seems as if some SIPaccounts could register and others could not. I don't think a firewall distinguishes between phone brands or SIP accounts.

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.

Did you check if iptables is blocking anything?
