I have a mini-carrier remote setup to one of my remote sites connecting via T1 to my CS1000 4.5 About a year ago we installed all new M3904 phones at this location. Within the last two months, users are complaining that their phones are automatically forwarding to specific extension without call forwarding being set. I have reset all cards, and units to no avail. My gut tells me it's user error, but I can't catch it. Has anyone seen this type of activity?
