We have had some changes in staff and I need the phones to sort of move with them. I need ext. 208 to become ext. 266. I also need it set up so that if someone calls 208 it rings at ext. 217. (There will no longer be a physical extension 208.) What is the best way to handle this? The phones at 208 and 266 are different models. 266 is a hybrid and 208 is a digital phone. Would the swap function work or should I delete the two extensions entirely and add 266 back with the settings of 208?
