i have a mics with a startalk - 1 business has 7 lines and another division or business has one line that has vm provided by the provider, they do not want it to use the startalk vm - it rings the attendant extension which has a vm box on the system - how can i let it ring at the attendant and the other persons phone without it going to the attendant's vm so that if it is not answered it will go to the provider's vm - right now it goes to the attendant's vm which is setup for 4 rings - i do not want to extend the attendant's rings to forward to vm
