DISA by handle script using CLID authorization

I would like to create a custom DISA using a handle script with Clid authorization.
I'll use two mobiles for this ClID authorization.
fexample: mobile 1 with ID 777
mobile 2 with ID 888

So the script I need sound like that (extensions_custom.conf):

Inbound call from ID 777 or 888) --> goif ID match nr. (if not hangup) ---> hold the line and capture the DTMF tones dialed --> go out thru from-internal --> dialing the capured nr.

I DON'T WANT USE SOMETHIG LIKE : exten => s,N,DISA(no-password|from-internal) it gives me a lot of problems.

I want use a script such as a transfering to the outside.

Thanks a lot.
