When receptionists leave, historically they've pressed Fwd All, then "Answ Svc" (Answ Svc is a phantom extension that redirects to a 1-800 answering service who take messages during our off hours), but when an outside call comes in, the phones just ring through and then ring endlessly. When the call comes in, one of the two reception phones will flash "Invalid fwd destination" for less than a second, then just display the callers name & number, BUT even when manually typing the 1-800 number after pressing Fwd All it doesn't say Invalid Forward Destination, it still just rings through to the office phone forever. The number for the answering service is good, if you pick up the phone and press the "Answ Svc" button it calls them, same as if you manually type that phantom extensions 4-digit number, as well as dialing the entire 1-800 number, the call goes through successfully each of those three ways, those two reception phones just don't seem to want to forward all calls. I've been sniffing around the system admin/DB programming menus but really didn't want to attempt to change anything before inquiring with folks who might have any suggestions first, thanks!
Edit: I'm seeing mentions of hunt group calls not being forwarded, these two phones are part of a hunt group (only two in the group), so if they're BOTH set (all of the phones in the hunt group) to forward all, will it not get forwarded?
