But you are wanting the STN Group (already ringing) to overflow after x seconds to a voice mailbox, right?
If you create a MBX for that STN Group, you can overflow to the MBX by pointing 'Next Port' to the VM Group. We called it the company's general mailbox - that's what the primary/no answer message says, while the recorded name still says "Operator" so that's the name heard when AA transfers to the STN Group.
Then we have only a couple of users that pick up the general messages and we put a MW 500 button on their keyset.
Is this making sense?
