I'm setting up a new Asterisk PBX, and I'm on the process of buying IP phones. I plan to add phones as needed, as we can't afford to buy them all at once. However, I do want to create a single extension for each person in the company, so we can start distributing them to clients.
My plan is to create multiple extensions, one for each person in the company, but have about half the phones. The phones support a single line. On Asterisk (using FreePBX), I would configure something like this:
Extensions 2001 -> Phone connected 2002 -> Phone connected 2003 2004 Routes 2001 -> Rings extension 2001 2002 -> Rings extension 2002 2003 -> Rings extension 2001 2004 -> Rings extension 2002
After we buy more phones, I will unfold the routes, so each number goes to its actual extension.
Will this work in practice? Does anyone have experiences doing something similar to this?
