I have a new installation with a UC540, 1 509G and 504Gs. If one inbound call calls the 509G (receptionist phone) it can be transfered to a 504G using an announced / attended transfer; however, if a second call comes in and I place the first call on hold, then I am not able to do an announced / attended transfer, only a blind transfer. In other words, if I have 2 active calls onthe 509G and I try to transfer one to a 504G, the call is transfered as soon as I press [Dial] is does not wait for me to announce and press [transfer].
I spoke to Cisco support and they told me that the reason this was happening was that each line of the phone could only handle 2 active calls. When my client decides to transfer, it would require a third line to do an announced transfer and this is not supported by the 504G phones.
Can anyone confirm / deny this logic?
Would there be any work aronds to give them similar functionality? We suggested that they park and un park calls to get around this limitation.
