What is the implication of adding a '.' to a variable name, for instance 'OutgoingCall.CallerID'?

Hello,

You should always ahead to ECMAScript convention for CCXML variable names, these rules, as I am sure you are aware, are that no variable can start with a numeral, can not contain spaces, can not be a reserved word, and also may not contain any punctuation. I do hope this helps and if there are any other questions please let us know as our team is most certainly standing by to be of service!
