I am having a dilemma and really would appreciate any help.
I am trying to set up my freepbx on a public IP address with 2 extensions also on public IPs. Both extensions can ring each other but as soon as the other extension answers the call you get the message “server failure”
I know public IPs are a security risk. Don’t worry this is just part of a test we are carrying out.
Thanks for your help in advance.
