Hi Jay,
There are quite a few ways to handle this request so I'll just
give you one take on this
Let's get some example DN's to work with here. We'll say the manager is @ 5555 and the
admin is @ 4444. You can set the Call Forward Busy settings on the 5555 DN page
to go to 4444 or you could actually put an appearance of 5555 on the 4444 spare
line button. Make sure to set the Busy Trigger on 5555 to 1 if you want all secondary
calls to go directly to the admin.
You will also want to set Call Forward Override
Cisco Unified CallManager provides a service parameter (CFA Destination Override) that allows the administrator to override Call Forward All (CFA) when the target of the CFA calls the initiator of the CFA, so the CFA target can reach the initiator for important calls. In other words, when the user to whom calls are being forwarded (the target) calls the user whose calls are being forwarded (the initiator), the phone of the initiator rings instead of call forwarding back to the target. The override works whether the CFA target phone number is internal or external.
When the CFA Destination Override service parameter is set to False (the default value), no override occurs. Ensure the service parameter is set to True for CFA override to work. See Service Parameters Configuration in the Cisco Unified CallManager Administration Guide
I'm going to assume you are running Unity Connection for
your Voicemail set up. Here is a nice thing to have for the Transfer
directly to VM. This will allow the admin to take a call for the manager
@ 5555 and send the caller directly to the manager mailbox if requested.
