I want a voicemail box to show messages waiting on three phone sets(DKT3214-SDL)in addition to the vm-box already programmed to these extensions.
I have three users at extensions 103, 104 and 105 who have voicemail already and it points to there extensions. We have a new voicemail box at extension 599. My users would like any messages in the 599 box to flash a button on there phone to prompt them to check the messages.
Please Note: They do not want to use the strategy forwarding feature where the voicemail is forwarded to one other voicemail box and then deleted from the original VM-box(599 for example)
Is this possible?
They know that they will have to dial into the 599 vm-box manually without using there Msg buttion on there phones. They just want a visual indicator that a message is waiting in the 599 vm-box.
The forwarding feature was originally used but they could not keep track of who checked the voicemail. And they all want a visual indicator that 599 has a voicemail to be checked.
Any help will be appreciated.
