68xx phones and mx-one obviously do not support overlap-sending, but 68xx supports "Live Dial Pad". Is it the same function with a different name? Background is the problem that SeC does not see the "busy-state" of the 68xx, if the User starts to dial on the dialpad. If then a inbound-call comes to the user via SeC the dialling will be interrupted. User is not happy with this situation...
