asterisk users - Aug 2006 - if command for or missing callerid?

I am looking for a way to make a decission in the dialplan if I have a 
caller id or not.

What I want to do with it:

Call on the PSTN line should either use astcc.agi with the caller-id in 
place as card number, or asking for the calling card number.

How can I make this "gotoif" ???

bye

Ronald

Gotoif($["${ISNULL(${CALLERID(number)})}" =
"1"]?ask4cardnum:doagi_astcc)

:-)
