Have a customer that has 2 sites(Both Merlin Magix 4.0) that are connected via fiber and RAD t1 modems. Sites are already setup to call back and forth via extension #'s. 3 employee's are moving from site A that has their 3 copper lines on an interm basis and would like to still make and receive their calls when they move to site B. Any help with this would be greatly appreciated!
