We had a disturbing phone call of a sexual nature come in to a church running a FreePBX system that uses voip.ms and OpenCNAM. The call came through as anonymous on the phone’s caller id, but voip.ms shows the number under Call Detail Records.
How can the number be available coming through voip.ms’ servers, but then be tagged as anonymous at the FreePBX/OpenCNAM lookup stage?
I do plan to set up a call route that drops anonymous calls.
