Historical Question?

Good Evening all,

Had an issue that came up as a result of the storms in the SE. I went in a box on an ssh and added a CF for a principals extension.

 database put CF 2105 4041234567
However the call when forwarded carried the originating CallerID through the system and the SIP provider rejected the call because the Calling Id was not one of the accounts did numbers.  

The fix was to change the Trunk Setting Cid Options from "Allow Any CID" to "Block Foreign CIDS" 

 My question is when did the Block option appear ? 


since quite a while but it used to be called something that was a little more ambiguous.

If I had to guess, it was maybe 2.1 or 2.2 that it was introduced? (I think it used to be Never Override CallerID.
