[Freeswitch-users] Outgoing calls from unknown users

[Frederick Pruneau]

Hi everyone!

I have found in the log files some international calls from unknown 
extensions. These extensions don't exist in my configuration. I tried to 
block them in my firewall (iptables on my freeswitch server) but they 
always use random IP adresses. Here is a short part of my Master.csv:

With my configuration, I need to be registered to make a call. I tried 
to call with an unregistered phone and I was not able to make a call. I 
don't know how they are able to do this but I need to block them. Is 
there something that I am missing in my configuration to block unwanted 
extensions to make calls?

Thanks in advance!
