[asterisk-users] Very strange registration problem

[Jonas Kellens]

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.
