Imagine this, the VM answers and says "press 4 for sales, press 5 to hear a duck quack" the selector codes acomplish the transfers. If sales is a group, you can set SC 4 to transfer to 71, and add all sales exts to calling group 1. Then all the sales exts will ring.
To hear a duck quack, set SC 5 to go to a sub menu, then create an announcement in a sub menu that sounds like a duck quacking. When hey press five, they will hear a duck quack.
You do not always get what you pay for, but you never get what you do not pay for.
