BCM450, R6, just upgraded. At night, reception hard call forwards her phone to x248, nite bell. They were complaining that it wasn't rining enough times before going to Gen Delivery. I upped the cfna on x248 to 10 rings, but it still goes to GD after 4 rings. I tried changing the cfna on reception, which is 201, to 10 rings. No matter what I do, I cannot get even 201 to ring 10 times when called directly, it always goes after 4 rings. What the?
