When you click on the Play&Record button it brings up the Media Master Tool Bar from there you can upload a pre-existing .wav audio file (this i understand by 'input') or you can use the phone to record the Greeting.
Call Handlers have the advantage that do not use up licenses therefore you can create as many as you like.
Based on your description i understand you would like the people part of the Hunt Pilot to receive the voicemail, my suggestion would be to add the intended users to a System Distribution list and then assign it as the message recipient in the Call handler. This call handler would need to have the extension of the hunt pilot.
The first red box is the path, so i selected my call handler in this case named mosi mosi mosi> Edit> Message Settings.
On the second box under Message Recipient i selected my test123 distribution list.
In this particular example no, the idea is that the members of the Hunt Group should receive the voice mail if none of them pick up the phone; due to the configuration design what we can do is asign the amount of users that you wish to include to the SDL (System Distribution List) so that they can all receive an exact copy of the message basically those "are users who need the same information on a regular basis". This is a more decentralized solution as everyone gets a copy of the message.
For further clarification the pilot members are just that within the CUCM side, CUC does not know about this therefore when we add the users to the SDL (System Distribution List) i would presume you want to add those who are part of the pilot members and you can add any additional members without being necessarily part of the pilot, let's say for example a main frontline receptionist.
