They apparently have issues with Shared Line Apearance so that might become an issue for the enduser. From a May 5th review...."UPDATE (May 05, 2009): Well I finally got my hands on one of these but haven't tested one out yet. The SLA firmware has been out for awhile and there have been several Aastra phone firmware updates since this product first came out. Apparently SLA still has problems which is what I expected to happen. Aastra tells me they are working hard on fixing it so stay tuned."

Aastra's website also has the old "get rid of your telephone service tech" verbage. The old so easy a Caveman could do it analogy kinda goes out the window when in the real world most endusers could not differentiate between a truck and a trunk.
