I am trying to replace an Avaya setup, but owing to the way the client operates and some user hostile features of the phones/3cx, I am facing pulling this. Can anyone suggest a configuration that will work simply. My client likes to put all calls on park; call the user; ask if they want the call; have them pickup call from park - OR - transfer call to VM. I tried to get them into attended transfer, but they insist on their way and to be honest the Cisco's and 3CX are clumsy. I have 504g's with sidecars at the front desk and everyone else has 504g's. Is there a phone that works better with shared parking? Cisco just display a keypad icon - useless. Is there a simple way to transfer to voicemail - no *4<ext> when i have a sidecar in place. Any and all help appreciated.
