I installed and obi200 and was going through the E911 and Ring2 setup, and found out I needed the Obi202 which has two ports. I was wondering if I will have any trouble switching out the obi200 with an obi202 once I receive it? What will I need to do in order to delete the info from the obi200 and install the new info from the obi202? Any help would be greatly appreciated.
