Normally, call transfer is completed by pressing the transfer key. Blind transfer on hook
and attended transfer on hook features allow the IP phone to complete the transfer
through on-hook.
When a user performs a semi-attended transfer, semi-attended transfer feature
determines whether to display the prompt "n New Missed Call(s)" ("n" indicates the
number of the missed calls) on the destination party’s phone LCD screen.
