Condition for adding a leading zero in Incoming Caller ID

Hey everyone …

I have a problem.

I want the asterisk to append a leading ‘0’ if there is no leading zero in the Caller ID. Also, dont append a leading ‘0’ if there is already a ‘0’ in the Caller iD. What should i do or what command does this ?
Please advice.


ExecIf, amongst several options.

Thank you very much for your help.
