“Line Occupied” and call forwarding
Also one other thing you may hear from customers is that they are getting the “line occupied” string. I was getting this sting a lot and found that enabling call forwarding on the phone lines to forward to another number really helps. It seems that sometimes customers will call the lines back after they hear the message and the server will pick up the incoming call while it’s trying to call out therefore not getting a dial tone and returning the “line occupied” string.
Thanks a lot for sharing this information.
