21:56:09 <mentax> mc_: Do I need to keep port 5060 open if I use port 7000? There are whole bunch of scanners trying to access this port and I receive an email about any unsuccessful attempt  
21:57:18 <mentax> System Alert: wrong_call_state 10001 to nouser (inbound) on unknown(unknown)
22:00:14 <mentax> over 9 000 emails every month
22:35:03 <brian-> mentax if nothing valid is using 5060 then no
22:36:13 <brian-> leave it open for your FS boxes - they probably are using 5060 to send invites.
22:36:16 <brian-> to the SBCs
22:46:33 <mc_> mentax: as brian- says, leave it open facing FS at least, but if you don't have any customers or carriers sending to 5060, then block it on the public NIC in kam
22:51:43 <mentax> I think carrier send invite to 5060 =(
22:52:56 <mentax> I will try to contact them and change the port to 7000
22:53:11 <mentax> hope it will work
