I have a customer with call waiting configured (IP Phone A, DN = 1000, Busy Trigger = 2).
But he wants that, when a second person rings him (IP Phone B, DN = 2000) he receives some kind of indication of the state of the Phone A, I mean, something like a locution: "Phone A is busy, please wait and you will be soon attended").
He wants to conserve the second call but we need a way to indicate Phone B that he is the second call. Anyone have an idea?
Thank you very much!
