Sometimes I get calls from withheld numbers. Sometimes they’re sales calls, local authorities, police, the privacy obsessed etc.
These calls come through as ‘1-pstn’ at the moment as that’s the name of the trunk and the userID on the SPA3000 bringing the call into FreePBX
How can I ‘handle’ these calls? How do I go about either preventing the trunkname/UserID being set as the caller ID or replace the 1-pstn with ‘withheld’ or ‘anonymous’ and how do I then direct them within FreePBX?
