I installed FreePbx 2.4.0.0 with asterisk 1.4.20.1
I need to create extension with numbers 3xx.
I can create it, but as soon as I try to call them, I receive an 603 Declined error.
If I just change te extension number (e.g. 4xx) everything works.
Why?
Is the 3xx extensions reserved?
Ho can I change the service that reserve it to another code, so I can use it.
Thanks.
