Special IVR for calls without caller id

What are you asking -- how to do the transfer, or how to detect there is no caller id, or something else?

The more specific your question, the more likely the answer -- although I find answers are pretty hard to come by in general on this forum. :(

I had to do somethign like that myself, only using contexts instead of the "digital receptionist" IVR.

What I did was
1) have the call come into the first context.
2) at the very beginning of that context, look at the caller id.
3) If no "real" caller id, then jump to another context.

The trick was that here in the US, if caller id is blocked it is still NOT empty -- it might be "blocked" or "anonymous"

So I used a regular expression to "return" the numeric portion of the caller id, and if THAT was empty (or did not match a complete phone number) then I knew there was no caller id.

BTW I found different voip providers would sometimes put a "+" at the beginning of their 'numeric' callerid, so it was a good idea to run the filter below anyway.

The regular expression I used is this:

exten => s,n,set(cid=${CALLERID(num)})
exten => s,n,gosub(stripcidtext,1) ; it's empty if no numeric portion

...
exten => stripcidtext,1,noop()
; the quotes below are important!!!!!
; 0 or more nondigits followed by digits, returns the digits
exten => stripcidtext,n,Set(regx="[^0-9]*([0-9]+)")
; returns first numeric portion of the string
exten => stripcidtext,n,Set(cid=$["${cid}" : ${regx}])
exten => stripcidtext,n,noop(cid=/${cid}/) ; display for debugging
exten => stripcidtext,n,return

Hope that helps. Good luck.

OK,
I found the Privacy Manager,
In the freePBX I just can select Yes/No

Where can i configure Privacy Manager,
for instance in Spain phone number are 9 digits not 10.
Thanks
