I use freePBX with a linksys SPA-3000. I get a lot of cold calls with a caller id which equals “INTERNATIONAL”. I Guess this code is used if the exact international caller id is not known or can’t bee determined. Is it possible to Blacklist or re-route these calls to a pre-recorded or voicemail box.
My apologies if this question has already been asked. I’ve searched but, can’t find the answer. I’m probably searching for the wrong thing
