That is all they have. If you are using this on the shop floor, then there really isn't much you can do. That is all they have. You can investigate hooking call manager into the loud speakers if you have them so that when a call comes in it is also announced over the speakers.

How are your 7920s working for you?
We run 3 here in our offices. We have spent a lot of time working on them and find them to be very reliable while standing still and somewhat reliable while roaming. 1.8 really helped out, but we get some interferance from neigboring offices who run 802.11b/g and an 802.11 bridge on our roof (not ours).
What is your expereince?
It is what it is!!
