is it possible in CCX to forward the call to a specific DN when no agent is online?
I know it from ANDTEK that there is a field where i can type in to which destination the call should go when no agent in on.
In CCX i guess it will be a script right?
Correct. You want to first determine if there are any agents logged in using a GET REPORTING STATISTIC step. Then you want to use the resulting value (variable) in an IF statement (something like IF (loggedInAgents < 1) THEN ) so that if the statement is True, then use a Call Redirect step to send the call to another number.
You can use also in the "Que to skill group" step the "Consider if" with this formula:
Object type - Skill group
Object - the specific skill group
Variables - Logged on
then add ">0"
Then from the fail branch of the "Que to skill group" go to "Label" with the DN you want to use.
