Block Anonymous/Uknown callers

[mudasar321]

Hi, is there a way I can block annonymous callers on a domain? I know call block works if we want to block any particular number not to call in. But some people block/hide their caller ID. How can I block those who have blocked/hide their caller ID's? If I go to call block I see call came in from 'Uknown' I blocked but still calls are coming in.

Can i block anonymous (NULL) callers in fusionpbx?

Blocking anonymous is relatively easy to do but you need to adapt to how your carrier(s) send anonymous calls. Use SNGREP to capture the initial INVITE message from the carrier and pastebin it.

If I start an anonymous call, I receive the attached message. But if i insert NULL in block calls, the call is not blocked

Hi, could you help me to block NULL calls? Can i translate NULL to number to block it?
