Stay where you are if
- Your connection is the weak link. If a video call from your office at two in the afternoon stutters, phone calls will do the same and no provider can fix it from their end.
- A fax machine is part of the work. The tones a fax sends were meant for copper and do not come back together as data. If signed forms reach you that way every day, hold on to a line for them.
- Numbers will move between islands or to the mainland. The address emergency dispatch receives comes from the account, not from where the phone is standing. If nobody will keep it current, do not switch.
- Something else is on that copper. An alarm panel or an older card terminal quietly sharing the line will stop when the line does. Find out what is attached before anybody cancels anything.
