Hello, I Currently use RocketVoip for my VOIP, with the plan I get 4 numbers for 29.95 including a 800#. All the numbers are tied to the main # so if you dial the 800 # it goes to the main #, however if someone else dials the local # it goes directly to the voice mail. How can I set up my system to allow two calls at once? I have a home office where phone calls are our life, and to be able to make 2 calls at the same time would be great. Please help. Thank you Thank you Thank you
