Change Caller ID when call forwarding is active

Hey guys.


Number A call number B.
Number B has call forwarding active to number C. When A calls B and the call is forwarded to C, I can see that the caller ID is A in C.

I need to see in C, A’s caller ID.

Is there a function or macro that I can modify to get what I need?

I am using Asterisk 1.2.13.

Thanks for your help.
