Hello Everyone,
I am bit new to freepbx , I need help on the below issue:
problem statement: I have configured all my extentions on free PBX for example 301-399 and I am reciving SPAM calls to one or two extensions at this time from some unknown extensions like 701 and 4001 , which are unknown to us
so far I made sure Allow Anonymous Inbound SIP Calls to NO and allow sip Guests. to NO
what else I need to make sure and how can I avoid this issue ?
