We have 9 phone numbers configured on our T1 from our provider. Currently they are all in the same hunt group and calling in on any of the numbers delivers the caller to our main call queue, which just rings the office. I would like to take one of those phone numbers on our line and dedicate it to a support phone number, which will ask the user to leave a voicemail. I already have an extension and voicemail set up which will automatically send a page to all the on duty support agents and I can successfully call from inside the office to leave a voicemail. I now need to allow external callers to call in and leave voicemails in the same VM box.
I am new to the asterisk system we have installed, as I have taken over for someone who has left the company without training me first. I have only basic knowledge of the system.
Can anyone give me ideas on what files I will need to edit to accomplish my goal? I am hoping this will not be too complicated a task for my basic skillset.
