I am trying to forward a phone to another phone and have it go to the VM of where i am forwarding it to and not go to my VM. I have tried every code and can't get it to work?

If you have DID extensions you could external forward it or if there is an unused trunk and extension you could do it that way. The system keeps the number that was first called through forwardings. To change numbers the call has to go out and back in to the new number.
