BLOCKED caller ID

Is it possible to block an outgoing caller id that has been spoofed? I received two calls within the past two days that came up BLOCKED. I fwd them to trapcall.com and received the number of (614) 738-xxxx. That person claims that they don’t know me, but I find it hard to believe that someone would BLOCK a callerid number which happens to belong to someone who is a friend of a friend. something hokey is going on here. Is there a way to reverse a spoofed caller id to find out what SIP/IAX provider it is coming from?

Turns out that that number belongs to a friend of my new best friend. My ex-wife’s recent ex-husband. :slight_smile:

Thanks in advance,
