Hi,

Sorry, I wasn't sufficiently clear.

The phone will register to a third party AP, and it will make calls. I have done that, and there is no special configuration required.

However, when you walk out of range of one AP, during a conversation, the phone may not handover correctly. As I understand the situation, the SMT-R200 AP's have a Samsung protocol running that controls the handover. This protocol is not defined in the 802.11 b/g specification and there is no approved standard for voice handover.

This is the reason Samsung will not guarantee operation with Third party AP's.
(and nor will Cisco, or Avaya or any other manufacturer).
