Query about auto answer


I have a following system: UCM6202 with GRP2614 phones.
What I need is: enable auto answer on all phones when called from specific extension (CEO extension). One solution as i think. creating paging group for every extension and CEO will call group extension for every extension. but thats mean any extension will call paging group will be answered. We need extension answers only if dialled from CEO extension


Make IVR with Whitelist
Set Alert-info there.

Boss call IVR (whitelist) then he dial desired extension with alert-info.
