When Officer A is absent, and Officer B is assigned to act in A's absence, they will expect callers and their messages to go to B.
I imagine this expectation relates to how their old digital system worked.
I don't want to spend ages configuring stuff every time they are in this situation (which is frequently). And then un-doing it.
(I will try adding A's extn. to Bs mailbox as an alternate extension to see if that provides the desired effect).
At this stage, my best answer is that B should have access to A's email (for the same reason they want to be getting their calls) and that voicemail messages for A will be going to that email account (thanks to the magic of NuPoint), therefore B will have access to them without me having to do anything at all (which is how I like it).
The default behaviour has often been questioned by this particular organisation - they *really* don't understand why somebody who isn't taking the calls still gets the voicemails.
Longer term, I really need to get them to work on an agreed extension range of "public, published" numbers. Then when they need to expose a number to the public for a particular service or project, we can create a ring group or something and not have all these problems.
And maybe a bit more Call Director. I created a Call Director for one of the sections and sent them instructions for recording the prompts. They thought it was too complciated, which was annoying, because they'd have loved it once it was up and running.
