[Asterisk-Users] CallerID retain on internal transfer

[Joe]

I was just looking through the Wiki for some info on how to retain the
original caller's callerid when make transfers to internal extensions, and I
came across the parameter below:

useincomingcalleridonzaptransfer=yes

There is nothing in the zapata.conf file from vers. 1.2.7 so I am wondering
if this is still a valid parameter. If not, does anyone know how I can do
this?

Thanks,
Joe
