Hello
I have installed 3cx pbx system on windows 2003 ,and I gave it public IP ,and I want my friends to register on it by xlite, every thing are ok , the can register and ring each other , the problem is they cant hear each other , all of them work behind ADSL router and have a NAT , but if there were 2 phones behind same NAT they can hear each other , I think the problem is NAT ,
How can I fix the problem without doing any configuration on thier routers (I dnt want to make port forwarding or things like that ) and there are some of friends work behind double NAT (1st NAT is router and 2nd is ISP NAT) . I tried STUN.3cx.com .
But I think ISPs blocks port 5060 for out traffic ( out my country , it still open for local traffic).
please help
Thanks
