DISA, Caller-ID override on outbound route is not working

Finally I found it, to get the trunkoverridecid to work under DISA

change from:
exten => 1,n,Set(_KEEPCID=TRUE)

to:
exten => 1,n,Set(_KEEPCID=FALSE)

This should only be done though by copying this entire section to extensions_override_freepbx.conf
