Hello, Every time fs receives a REGISTER it will look up the user trying to register (if the profile is configured to authenticate) in the directory path. You can register via any profile if configured. You can control what user may register where by enabling multi-domain as per https://wiki.freeswitch.org/wiki/Multiple_Companies. By default, the directory.xml is as follows: <include> <!--the domain or ip (the right hand side of the @ in the addr--> <domain name="$${domain}"> ... <groups> <group name="default"> <users> <X-PRE-PROCESS cmd="include" data="default/*.xml"/> </users> </group> ... So, as you can see, there's only one domain directory ($${domain} which is the ip address of your server) which has only one group called "users" which *includes* any xml in "default/" hope this helps.

I am studying opensips and kamailio, but to be honest, I am a little affraid of them - just because I am not sure if I can figure out every situation in route.
My environment is strictly controlled with iptables drop policy and just friendly traffic is allowed.
What I understood by now is that I must have a profile for every NIC used to route traffic.
What I don't get yet is how directory relates to profiles. In file directory/default/example.com.xml there is a user "joe" which have a gateway defined inside it and that sofia shows in every gateway availble (expect in internal)
Just to make me more confused: https://wiki.freeswitch.org/wiki/SBC_Setup
In which internal and external are binded to the same ip+port but to different vlans. How vlans tags are binded to internatl and external profiles?
Atenciosamente,

At the very least start by looking at Homer (http://sipcapture.org/) which works beautifully with kamailio (i assume also openSIPS) and freeswitch. and it generates by default some nice graphs and alarms.

but that's part of a job for an end-to-end system designer, it's not something specific to a particular piece of software.
For the scenario that Valter has described, FreeSWITCH (or two servers in a cluster) will do the job just fine. But of course it needs to be designed, configured and tested properly, with security in mind.
I would agree, it's good to place Kamailio as the first-hop Internet gateway if you need to process INVITEs from unknown sources in Internet. It has nice features that minimize the impact of various DOS attacks or hacking. Also if you need to scale up, Kamailio will serve nicely as a load-balancer. But there's nothing wrong in placing FreeSWITCH alone in the Internet if you know what you're doing.

The first was the problem, where attacker somehow got login and password (i think they broke thier ATA) from clinet and used it. But for this client there was a limit of one line. I used limit module with local database. What attacker actially did, is that they used REFER attack, where they put their own number as a referrer, and opened unlimited lines to PSTN. So the, solution was - to replace limit functunality to opensips.
The second - it is not actually the FS issue. It is because Freeswitch is not flexible enouph to work at the low level where Kamailio or opensips operates. E.g, we programmed opensips to lookup for UserAgent database, we add useragent for each client manually. And only using client's IP and user-agent we allow this user to call to PSTN. We watch for blacklists of IP adresses, subnets. If it comes from Gaza, Panama, China we block it. And a lot of other things. Most of them is not out-of-box in opensips, but it is not hard to implement. All this functionality is very important. We lost about $10k last time. This is very serious.

I love freeswitch, but frankly I would not recomend to set it as
SBC. I
personally faced two attacks where FS was not good at. And we lost a lot of money. It works perfectly as NAT between internal and extenal networks, actually in everything but it is weak as a firewall. Stanislav knows that, he helped me to resolve the problem first time when it happend. I cannot go into details as this is open forum. You need to put either kamailio or opensips in front of FS.
Strongly agree.
